Extra Upgrade

^{Mistveil → Feats → Extra Upgrade}
Prerequisite: Dragonfire Cannon class feature

Benefit: After spending extra time with your Dragonfire Cannon you’ve discovered how to further upgrade it. When you select this feat you can choose to add one additional Cannon Upgrade to your Dragonfire Cannon. In addition to the normal amount of time it takes to apply an upgrade, it also costs the wielder raw materials that are worth an amount of gold equal to 100 times the number of upgrades the weapon already has.
