Fighting Style
You adopt a particular style of fighting as your specialty. Choose one of the following options. You can’t take a Fighting Style option more than once, even if you later get to choose again.
Archery
You gain a +2 bonus to attack rolls you make with ranged weapons.
Defense
While wearing armor, you gain a +1 bonus to AC.
Dueling
When you are wielding a melee weapon in one hand and no other weapons, you gain a +2 bonus to damage rolls with that weapon.
Great Weapon Fighting
When you roll a 1 or a 2 on a damage die for an attack you make with a melee weapon that you are wielding with two hands, you can reroll the die and must use the new roll, even if the new roll is a 1 or a 2. The weapon must have the two-handed or versatile property for you to gain this benefit.
Protection
When a creature you can see attacks a target other than you that is within 5 feet of you, you can use your reaction to impose disadvantage on the attack roll. You must be wielding a shield.
Two-Weapon Fighting
When you engage in two-weapon fighting, you can add your ability modifier to the damage of the second attack.

Mechanist Ingenuity
Through the use of your superior intellect and cunning, you have learned unique ways to increase your chance of success when subject to certain attacks. Whenever you are the target of an attack or spell that requires you to roll a saving throw, you can choose to add your Intelligence modifier in addition to any other modifiers on the saving throw. You can use this ability before or after your roll but before you know the result. At first level, you have one charge on this ability. At 10th level, the number of charges of this ability increases to three. You regain all expended charges on a long rest.

Spark of Opportunity
Starting at 2nd level, because of your scientific mind, you are able to recognize momentary weaknesses in your enemies defenses. Once per use of this feature, you can give yourself advantage on a single attack roll. You have a number of uses of this feature equal to half your Intelligence modifier (rounded up) and all expended uses are regained after a short or long rest. At 14th level in this class the total number of uses of this feature increases to your Intelligence modifier per rest.

Mechanist DC
Some of your class and archetype features require your target to make a saving throw to resist the feature’s effects. The saving throw DC is calculated as follows:
Feature save DC = 8 + your proficiency bonus + your Intelligence modifier

Augmentation Archetype
At 3rd level, you choose an archetype that you strive to emulate, in addition you alter your physical form in a significant way. Choose either Juggernaut, Deadeye or Spark Smith, all detailed at the end of the class description. Your choice grants you features at 3rd level and again at 7th, 11th and 15th level.

Ability Score Improvement
When you reach 4th level, and again at 6th, 8th, 12th, 16th, and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can’t increase an ability score above 20 using this feature.

Extra Attack
Beginning at 5th level, you can attack twice, instead of once, whenever you take the Attack action on your turn. The number of attacks increases to three when you reach 11th level in this class.

Minor Modification
Beginning at 5th level, you further mechanize and/or augment your physical form for different purposes and with different effects. Choose one of the following minor modifications. You make one additional choice at 10th, 13th and (2) at 17th level in this class. Some options may be chosen more than once.
You can attempt to change your modifications after a long rest, doing so requires a tinkerer’s tools (intelligence) check, the DC for this check is equal to 13 plus twice the number of modifications you are attempting to change. On a failed check, you are unsuccessful in your efforts and must make an additional check to attempt to fix your original modifications.
The DC to fix a modification is 15, if this check is also failed, you no longer benefit from it as it is non-functional. You may repeat the repair check after a short rest.

Flamethrower
As an action you can now release a 20-foot by 5-foot line of flames in front of you. Each creature in the line must make a Dexterity saving throw. A creature takes 2d4 + your intelligence modifier fire damage on a failed save, or half as much damage on a successful one. The fire ignites any flammable objects in the area that aren’t being worn or carried. You have two uses of this ability, all expended uses recharge on a short or long rest. Can be chosen a maximum of one time.

H.A.R.M.
You implant yourself with the Huge Adrenaline Release Mechanism. As a bonus action you may trigger this mechanism for a specialized effect. The mechanism comes in two varieties, you may choose only one.
H.A.R.M. Ω When you are wielding a ranged weapon this allows you as your action this turn to attack any number of creatures within a 15-foot radius of a point you can see within your weapons range. You must have ammunition for each target, as normal, you make a separate attack roll for each target
H.A.R.M. ß When you are wielding a melee weapon you can add half your Intelligence modifier (rounded up) to all your attack rolls this turn, in addition, you can use your action to move up to half your speed and make a melee attack against any number of creatures that came within 5 feet of you during this movement. You must make a separate attack roll for each target, and this movement provokes attacks of opportunity as normal.
Whichever variety you choose, at the end of your turn, until the beginning of your next turn, enemies have advantage on attack rolls made against you and you have disadvantage on saving throws you make as you are briefly worn out from the sheer intensity of your efforts.
Armor Plating
You graft layers of metallic plates beneath your skin, as a result you gain +2 to your AC and develop resistance to cold damage and fire damage.
Augmented Targeting System

Mechanical Twitch
You replace the tendons in your body with alchemically enhanced metallic strands and as a result, whenever you score a critical hit with a weapon attack, you may perform an additional attack as part of your attack action with that weapon. This effect can only trigger from your standard attack actions and not from the bonus attacks granted by this ability.

Mechanical Perfection
At 17th level, a wondrous merging of the biological and the mechanical, you become greater than the sum of your parts. You no longer suffer any of the frailty of old age, and you can’t be aged magically. You can still die of old age, however. In addition, you no longer need food or water.

Static Overload
At 20th level, you gain the ability to temporarily short circuit all the modifications on and in your body to produce a powerful release of energy. Each creature in a 60-foot cone in front of you must make a Dexterity saving throw.
On a failed save, a creature takes 15D8 lightning damage, 15D8 force damage and is pushed away from you by 15 feet. On a successful save the creature takes half as much damage and isn’t pushed. In addition, you take 10D8 fire damage from the overload and suffer one level of exhaustion. This ability is only usable once and recharges after a long rest.

Augmentation Archetypes

Different mechanists choose different approaches to executing their combat superiority on the battlefield. The augmentation archetype you choose to emulate reflects your approach.

Juggernaut
Those mechanists who are after superior melee combat tactics pursue the Juggernaut archetype. Juggernaut’s unique self modifications offer both offensive and defensive capabilities that are hard to match. As a Juggernaut you are not only a brutal force to be reckoned with on the battlefield but also an intelligent and tactical combatant.

Quadribrachial
When you choose this path at 3rd level you attach and fuse two mechanical arms to your spine just below your existing biological arms. Your new arms can perform any normal task that your biological arms can but are not proficient with any weapons or shields, they are however proficient in unarmed strikes. Your new arms can be used to make two unarmed strikes as a bonus action when you take the attack action on your turn. The attack rolls for these strikes can use either your Strength or Dexterity modifier, the bludgeoning damage for each strike is 1d4 plus your Intelligence modifier.
Your new arms also give you advantage on any grapple checks you make. You count as one size larger when determining your carrying capacity and the weight you can push, drag , or lift.
At 6th level the unarmed strikes from your mechanical arms are considered magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Deflective Defense
At 7th level, you have further strengthened the link between your mind and your mechanical arms. When you are the target of a weapon attack, you can use your reaction to engage your arms defensively and attempt to deflect the strike. Roll 1D4+1 and add the result to your AC until the start of your next turn, the triggering attack is also subject to this increase in AC. You can use this ability a number times equal to half your Intelligence modifier (rounded up), you regain all expended uses after a short or long rest.

Spark Bot
At 11th level, your studies of the mechanical and the biological allow you to merge the two into the creation of a construct which you control via telepathic link. Discuss the cost and time required for this task with your DM. You can only control a single construct at any one time. The statistics of the spark bot are detailed under “Mechanist’s Creations” below. On each of your turns you can command your creation telepathically (no action required). You decide what action the construct will take and where it will move during your turn, or you can issue a general command, such as to guard a particular chamber or corridor. If you issue no commands, the construct only defends itself against hostile creatures. Once given an order, the construct continues to follow it until its task is complete. Certain actions have a “Limited Use”, these have a number of charges equal to your Intelligence modifier. The construct regains all expended charges on a short or long rest.

Charged Up
At 15th level, you have learned to push your mechanical arms to their limits. Your unarmed strikes with your mechanical arms now use a D8 for their damage die, you have also have discoverednfow to concentrate electrical energy on them and discharge it. Once per turn on a hit with one of your unarmed strikes you can choose to do an additional 2D8 lightning damage.
You also gain the ability, once per turn, to instead of dealing this additional lightning damage, attempt to stun the target. On a successful unarmed strike the target must roll a Constitution saving throw, on a failed save the target suffers the stunned condition.
You have a limited number of charges on the second part of this feature, equal to half your Intelligence modifier (rounded up). All expended uses recharge after you have taken a short or long rest.

Deadeye
Those mechanists who are after superior ranged combat tactics pursue the Deadeye archetype. A Deadeye’s self modifications offer both offensive and defensive advantages. As a Deadeye your preferred style of combat is to stealthily move between long distance vantage points, peppering your enemies with ranged projectiles or patiently waiting for a single high value target to present itself.

Mechanical Advantage
When you choose this path at 3rd level, in the pursuit of ranged combat superiority, you use a combination of devices and enchantments to augment your existing biological arms and eyes. These augmentations grant you several benefits:
- Your arms augmented strength allow you to deal an additional 1D4 damage on your weapon attacks.
- Your arms augmented speed allow you to make one additional ranged attack as a bonus action when you take the attack action on your turn.
- Your augmented vision gives you advantage on all investigation and perception checks that rely on sight.
At 6th level the ranged attacks from your mechanically enhanced arms are considered magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Defense Drones
At 7th level, you have developed a network of defense drones that can be easily rebuilt or replaced on a short or long rest. As a reaction when a creature you can see within 60 ft. of you makes an attack roll, you can telepathically command one of your drones to distract that creature. This imposes disadvantage on all attacks made by that creature this turn, including the triggering attack, until the start of your next turn. The drone is destroyed in the process. You can have a maximum number of drones equal to half your Intelligence modifier (rounded up).

Clockwork Spotter
At 11th level, your studies of the mechanical and the biological allow you to merge the two into the creation of a construct which you control via telepathic link. Discuss the cost and time required for this task with your DM. You can only control a single construct at any one time.The statistics of the construct spotter are detailed under “Mechanist’s Creations” below.
On each of your turns you can command your creation telepathically (no action required). You decide what action the construct will take and where it will move during your turn, or you can issue a general command, such as to guard a particular chamber or corridor. If you issue no commands, the construct only defends itself against hostile creatures. Once given an order, the construct continues to follow it until its task is complete. Certain actions have a “Limited Use”, these have a number of charges equal to your Intelligence modifier. The construct regains all expended charges on a short or long rest.

Charged Ammunition
At 15th level, you have learned to impart electrical energy into ammunition as you fire it. Your ranged attacks now do an additional 1D6 lightning damage.
In additon you gain the ability, once per turn, to choose to add a massive amount of charge to the ammunition instead. In doing so, your ranged attack does 1d8 plus Intelligence modifier lightining damage and explodes just before hitting the target in a shaped charge. If the attack roll hits, the target must make a Constitution saving throw. On a failed save the target is blinded until the beginning of your next turn and pushed back 10-feet away from you. On a successful save, the target is not blinded and is not pushed back.
You have a limited number of charges on the second part of this feature, equal to half your Intelligence modifier (rounded up). All expended uses recharge after you have taken a short or long rest.
