Iron Brute Engineer, Engineer

You tinker with a suit of state-of-the-art powered armor for use in your adventures. Your armor is a size larger than you (Large for a Medium engineer, Medium for a Small one), with an engine to power it, and hydraulics and gears to lift the weight of the armor as well as enhance your own strength. The arms feature mount-points for your favorite weapons, and as you increase your engineer level and tinker with your creation, you add more potent defensive and offensive features.
Tool Proficiency: You gain proficiency with mechanic's tools. If you're already proficient with them, you may choose another tool proficiency from the engineer class options, above.
You also add the gadgets from the Iron Brute list to the gadgets that you may choose from, any time you gain a new gadget or trade one of your existing gadgets for a new one.
Features:
Powered Armor

Powered Armor

3rd-Level Engineer Feature
You complete the first prototype of a suit of powered armor. This suit acts as heavy armor, using the stats on p. 51, though you are proficient with it even if you lack Heavy Armor proficiency. While wearing it, you have Armor Class 16 (your Dexterity modifier provides no benefit). As long as the suit has power, its weight doesn't count as encumbrance, and there is no minimum Strength requirement – though it does impose disadvantage on Dexterity (Stealth) rolls. Instead, your Strength is increased by 2 (more at higher levels) while wearing the armor.
You can mount weapons (gadgets or ordinary) to the arms, removing the Heavy property and giving advantage on rolls to resist disarming. It takes a short rest to switch mounted weapons, and as long to don or doff as other heavy armor. If the DM allows layering armor (p. 50), you can wear a single suit of light armor under your powered armor, for a +1 to AC – and the further benefit of having some kind of armor on when you don't feel like clomping around in your Iron Brute.
If the unit loses power (enters a dead magic area or antimagic field, or is successfully targeted with a dispel magic spell against DC 10 + your Gadget Effect Level), the armor becomes inert – it still provides the same AC, but it no longer grants a bonus to strength, and its full 100 lb. weight is added to your encumbrance. Like your other gadgets, your armor doesn't work for other users.
As you increase your engineer level, you make various upgrades to your armor, giving it the following improved stats at the levels specified.
Engineer Level Strength Increase Armor Class Walking Speed
3rd +2 16  +0 ft
7th +3 17 +0 ft
10th +4 18 +5 ft
14th +5 19 +5 ft
17th +6 20 +10 ft
Toxin Filters

Toxin Filters

7th-Level Engineer Feature
You have filtered your powered armor against airborne and other toxins. As long as you are wearing your armor, you have advantage on all saving throws against inhaled and contact poisons, including spells such as stinking cloud, cloudkill, green dragon breath, etc. You also have resistance to poison damage from these sources, as long as you have your armor on.
Energy Shielding

Energy Shielding

10th-Level Engineer Feature
Your armor gives you resistance to one of the following kinds of damage, chosen when you gain this ability: acid, cold, fire, force, lightning, or thunder. You can choose to change the kind of damage that you are protected from, whenever you complete a short or long rest. Upon reaching 14th level, any time you change your energy shielding, you may choose two of the above damage types to shield yourself from.
Damage Control

Damage Control

14th-Level Engineer Feature
You finish an overhaul of your armor which helps to dissipate and absorb damage when you are hit. While wearing your armor, you have resistance to all bludgeoning, piercing, and slashing damage.
Heavy Weapon Mount

Heavy Weapon Mount

17th-Level Engineer Feature
Your powered armor is strong enough to mount one of the exotic firearms in Chapter 6, even if your Strength isn't sufficient. This weapon takes up one of your weapon gadget slots, and benefits from any relevant weapon enhancements. You also gain proficiency with such weapons at this level.
