Artificer subclass
Armorer
Custom arcane armor with Guardian and Infiltrator configurations.
Armorer starts by changing the normal Artificer play pattern through Tools of the Trade; Armorer Spells; Arcane Armor; Armor Model, giving the subclass its first clear mechanical identity.
Later features such as Extra Attack, Armor Modifications, Perfected Armor expand that identity at higher levels, so the subclass has a clearer role in combat, exploration, utility, or support.
