Mecha Leash

Your Arcanomech (mech) can collect AP and Twilight Materials as if a pet. Each time you create your mech its this mech no matter which form you choose it to be. Additional AP earned becomes Twilight Materials. The mech can spend TMs on boons but cannot take the pet awakening boon. All other rules apply for boon purchases including spending twice amount to replace a boon. The pet counts as Warforged and may take the Warforged racial boon. The mech counts as a fighter for class boons and learns the fighter features referenced and changed by the class boon. You can cast mending as a bonus action which heals for an additional 10 hp per boon the mech has (only boons from twilight material purchases, epic, class, racial) The mech can receive healing as if a humanoid creature. Overhealing becomes temporary hit points which disappear at the end of combat.

(Your mech still counts as your mech for your abilities.)
