Magitech Hero

Martial Archetype
Comments from the Finger: The Magitech Update begins! Easily my favorite homebrew to come out of GiantITP, the Magitech Templar (original here) is touted (rightfully, I might add) as Iron Man for D&D. Infinitely modular and with the right balance of magic and tech, this class was both flavorful and mechanically sound, despite having a mostly non-linear class feature selection system. It's this very system of non-linear upgrades we wanted to preserve as closely as possible at the core of the Magitech classes we've written to accompany the Hero.

     Another thing of note is that the Hero is the single longest sub-class we've written for 5e, of which the vast majority is the Magitech Upgrades.

    Finally, a note on balance. The Magitech Hero can be many things, and as such runs the gambit from weakly to strongly optimized. A character which chases the main tracks of prerequisite upgrades will likely achieve the most power in terms of sheer number of abilities, but will sacrifice the customization that makes this class so powerful. At higher levels, its damage per round doesn't quite stack up to the Eldritch Knight, though it will probably out-muscle the Champion.

Magitech Hero

The archetypal Magitech Hero is a warrior who possesses a sophisticated suit of magical armor which can be upgraded and modified, making them extremely versatile and dangerous combatants. Some upgrades make the Hero a towering machine of war, others a craven shadow on the wall, and others still a flying mechanical wonder, capable of firing beams of energy from his eyes and palms. No matter the configuration, Magitech Heroes are a formidable force.

Magitech Armor

At 3rd level you gain a suit of magic armor from your church (or family, clan, king, or other organization as appropriate for your character). You may choose any type of armor that you are proficient with. It is of masterwork quality, but is otherwise typical of armor of that type. At any time you may return to any church of your order, and they will provide you with the facilities needed for you to repair, improve, or enchant it, though you must still pay for materials and other associated costs.

     Magitech Armor is more powerful than a regular magic item. Only an antimagic field and areas of "dead magic" suppress it's abilities, rendering it mundane masterwork armor until the magic suppression ends. When suppressed by an Anti-Magic Field or similar effect, you also lose any abilities gained from Magitech Upgrades.

Magitech Upgrade

At 3rd level, you may select any two Magitech Upgrades for which you meet the prerequisites. You may not use one of the Upgrades selected at 3rd level as a prerequisite for the other. You may select an additional upgrade at 7th, 10th, 15th, and 18th level.

     Magitech Upgrades apply only while you wear your Magitech Armor. Upgrades that cast a spell require no verbal or somatic components. If an Upgrade calls for a saving throw, the DC is equal to 8 + your proficiency bonus + your Intelligence modifier. Your magitech level is equal to your fighter level.

Magitech Upgrades

If a magitech upgrade has prerequisites, you must meet them to learn it.

Armored Mind

You have advantage on saving throws against being charmed and saving throws against being frightened.

Armor Sentience

Prerequisite: Energy Shield and Armored Sense

Your armor gains a more complete sentience and gains the ability to transfer some if its magical power into spells. Your armor has 6 charges. You can use an action and expend 1 or more charges to cast one of the following spells from it: lightning bolt (4 charges), magic missile (1 charge), protection from energy (2 charges), or thunderwave (1 charge). If you expend the armor's last charge, you may take no actions and can't move for 1d4 rounds, after which the armor regains 1 charge. Your armor regains 1d4 + 2 expended charges daily at dawn.

Armored Sense

Prerequisite: Energy Shield

Your armor gains a limited sentience and may alert you early to threats. You gain darkvision and the effects of see invisibility with a range of 30 feet while you wear your armor. You may add double your proficiency bonus to Investigation and Perception checks (including Passive Perception checks.)

Armored Stability

While you wear your armor, you have advantage on ability checks and saving throws against being moved or knocked prone, such as from a Shove action or Trip Attack maneuver.

Burrow

While you wear your armor, you gain a burrow speed equal to half your base movement speed.

Damage Reduction

Prerequisite: Energy Shield

You may cast protection from energy. You must complete a short or long rest before using this feature again.

Dauntless

Prerequisite: Armored Mind

While you wear your armor, you longer need to eat or sleep and are immune to magical sleep effects. You are also immune to being poisoned.

Dive Attack

Prerequisite: Speed, Propulsion

If you move at least 10 feet downward before making a melee attack against a creature, you have advantage on your first attack against that creature and may add your proficiency bonus to that attack's damage.

Energy Shield

You can cast shield. You can use this ability again after taking a short or long rest.

Evasion

Prerequisite: Speed and Stealth

You gain the Rogue Evasion and Uncanny Dodge features.

Explosive Energy

Prerequisite: Power Fist, Repulsor Rays

As an action, you can channel all of the energy of your Magitech Armor into an explosive electrical attack. Each creature within a 30 feet of you must make a Dexterity save. On a failed save a creature takes 3d6 points of lightning damage for each point of your proficiency bonus, or half as much on a successful one. After you use this ability you can take no actions and can't move for 1d4 rounds. You must complete a short or long rest before using this feature again.

Flame Thower

You can fire a stream of flame at your foes as an action. Each creature in a 15-foot cone must make Dexterity saving throw. A creature takes 4d6 fire damage on a failed save, and half as much damage on a successful one. You must complete a short or long rest before using this feature again.

Frost Missile

As an action, you may fire a Frost Missile. The missile has a range of 5 feet times your magitech level. Make a ranged attack. If it hits, the missile deals 2d8 points of Cold damage, and the target is can move only half its maximum speed until the beginning of your next turn.

Great Strength

Your armor assists you in physical exertion. While you are wearing your armor, increase your Strength score by 1, to a maximum of 20. In addition, your lifting and carrying capacity is doubled.

Interpose

Your armor is so imposing that enemies cannot ignore your presence. Any space that you occupy blocks the line of sight and line of effect of any enemy attack on the same or lower level of elevation as you. Thus this gives objects and creatures total cover from effects that require a straight line of effect through your square. Friendly creatures that are familiar with your presence may target others through your square normally. Enemies on higher elevation then you ignore this effect, as do enemies that are larger then you.

Light Beams

As a bonus action, you may fire beams of light from your eyes. The light beams have a range of 5 times your magitech level (max 60 feet). Make a ranged attack. If it hits, it deals 2d4 points of Fire damage. After you use this ability you may not use it again for 1d4+1 rounds.

Mecha Transformation

Prerequisite: Power Fist, Transmutation

Your armor can become a towering machine of war. As an action, for 1 minute, your size triples in all dimensions, and your weight is multiplied by 27. This growth increases your size by two categories—from Medium to Huge, for example. You also has advantage on Strength checks and Strength saving throws. Your weapons do not grow to match your new size, but your Power Fist does. While the Power Fist is enlarged, your attacks with it deal double damage. In addition, your armor is Fortified as per the Transmutation feature while you are enlarged. You must complete a long rest before using this feature again.

Planar Adaption

Choose a plane of existence other than the Material Plane. You may move and act on that plane as if you were a native, and do not take penalties associated with being a non-native to this plane. This upgrade requires DM approval, as the cosmology of various game worlds vary dramatically.

Power Fist

Your armor has a Power Fist built into one of its arms, which is a one handed melee weapon that deals 1d8 bludgeoning damage, and cannot be disarmed. You are proficient with the Power Fist. You may hold or otherwise manipulate a weapon, shield, or other object on the same arm as your Power Fist, though you may not attack with your Power Fist and use an object or weapon held in that hand on the same turn.

Propulsion

Prerequisite: Speed

While you wear your armor, you gain a fly speed equal to your base movement speed. You may not take the Dash or Disengage actions while flying. Flying for more than 1 minute at a time drains your suit of power, after which you fall and can take no actions nor move for 1d4 rounds.

Repair

Prerequisite: Energy Shield, Damage Reduction

At the beginning of your turn, you heal a number of health points equal to your proficiency bonus if you have no more than half of your hit points left. You don’t gain this benefit if you have 0 hit points.

Repeating Crossbow

Your armor has a special masterwork repeating hand crossbow built into one of its arms, which is a ranged weapon that deals 1d6 piercing damage, has range 30/120 feet, cannot be disarmed, and possesses the Light weapon property. You are proficient with this weapon. You may hold or otherwise manipulate a weapon, shield, or other object on the same arm as your Repeating Crossbow (including a Power Fist). Your armor contains an extradimensional space which can store up to 100 bolts, and the repeating crossbow automatically loads any stored bolt of your choice automatically requiring no action.

Repulsor Rays

Prerequisite: Power Fist

You fire a number of rays equal to your proficiency bonus. Make a ranged attack for each ray. These rays each have a range equal to 5 feet times you magitech level. If hit, a creature takes 1d6 plus your Intelligence modifier force damage. In addition, creatures hit by rays must make a Strength saving throw with a DC equal to 5 times the number of rays that hit them. Each creature hit makes only 1 saving throw. On a failed save, a creature is pushed back 10 feet.

Speed

Your base speed increases by 10 feet.

Spider Climb

While you are in your armor, you gain the effects of spider climb.

Stealth

Prerequisite: Speed

While you wear your armor, suffer no disadvantage on stealth checks due to it and you may add double your proficiency bonus to Dexterity (Stealth) checks. You may also cast invisibility. After using this, you cannot cast invisibility again until you complete a long rest.

Transmutation

Prerequisite: Power Fist

As an action, you can change the shape and form of your armor to assume the appearance of a normal set of clothing. You can also take an action to Fortify your armor for 1 minute. During this duration, you move at half speed in your armor, and have resistance to Bludgeoning, Piercing, and Slashing damage. After using this, you cannot Fortify your armor again until you complete a long rest.

Webbing

You can cast web. You cannot use this feature again until you take a short or long rest.
