Several SFX involve taking a die from the Doom Pool and adding it to your pool, then steping it up and returning it to the Doom Pool.
SFX: Berserk. Add a die from the doom pool to one or more attack actions. Step up the doom pool die by +1 for each action; return it to the doom pool when you’re done.
SFX: Eye of Agamotto. Add a doom die to your next action including an Arsenal of the Herald or Master of the Druidic Ways power. After your action, step up the doom die and return it to the doom pool.
What if that Doom die is a d12? Does it mean the character gets a free d12 to his actions as long as there is one in the Doom Pool?
On one hand I can understand the logic of "those characters shine when the situation is really dire".
On the other hand, a free d12 on all actions seems a bit broken, and unfair to the other characters.
How to handle those situations?
