A workshop is not for you - you prefer to provide logical and technological support on the front lines. You gain 10 hit points, reduce arcane spell failure from armor by 10%, and have a +2 to both confirm critical hits and critical damage (before multipliers). Any weapon you wield in your main hand gains a +2 enhancement bonus
(which stacks with the Enchant Weapon spell), and you gain the ability to enchant your crossbow to instantly reload itself, allowing you to lay down incredible amounts of fire for a short period of time.
The 10% reduction to arcane spell failure from armor does not appear to affect the arcane spell failure from warforged plating.
