Tinman is a lvl 6 artificer currently, which means the following:
Meet the "Caster Level" requirement up to 8th lvl.
Can Craft: Armor/weapon, wondrous, potions, scrolls, wands.
Craft Rate: 1000 gp/craft day OR 3000 gp/real day.
Note: While I don't mind making 'cheaper' items like a scroll of true strike, in general, due to how crafting works, I'd prefer to work on more expensive items.
Rates:
75% of the market cost.
