Issue Description:

Casting Flame Burst does nothing. No DC, no attack roll. Doesn't even get the "Plink casts Flame Burst" message.

Depends on the CL (duration). This is an illegal (unless you're a member of the Tower, and even then there are rules about the legality) and immoral summon theme that can cause your PC social suicide if they're found to be using it.

The RP consequences allow for it to be a stronger theme mechanically.
