Chromatic Destroyer Heritage
You can have multiple breath weapon spells active at the same time. You don't gain extra actions, so if you succeed with multiple breath weapon spells, you'll generally have to choose which one to use.
You gain a +2 attack bonus with empowered breath weapon spells.
Once per day, turn a failed breath weapon re-use roll into a success.
One battle per day, gain resist dragon attack 16+ (all attacks made by dragons; dragon must roll natural 16+ with the attack or it deals only half damage).
