But you're getting rewarded Draconium.

You get to be your very own reserve feat!

Draconium reserve feat.

Prerequisites One metabreath spell of 2nd level or higher, and a breath weapon that deals damage.
Benefit As long as you have a metabreath spell of 2nd level or higher, you may choose to use your breath weapon as a full round action, instead of a standard action. Doing this, increases the damage of your breath weapon by 1d6 per spell level, and makes half of the damage, arcane damage, and thus bypass resistance and immunity.
