Homebrewed equipment is listed below. Some of these can be crafted, but only after being invented, as listed on the page. The most likely skill to be required is listed, but other skills can be substituted if applicable.
Additionally, at GM discretion, you can attempt to craft a higher quality version of the equipment. You can increase the DC by 5 to increase the bonuses granted by the item by 2 – this must be declared before making the check. If this check is unsuccessful, it counts as a failure, even if you would normally meet the DC of the item.
This would mean that an item that normally grants a +4 bonus would grant a +6 bonus if successful.
