Is there a guideline for creating creature abilities. I want to convert a sand giant's "sand blast" ability from 4e to BBF.
Actually - there is in fact a system for balancing special abilities. It's called the Effects Factory - a process for creating special abilities, poisons, traps, etc. It derives a rank value. Unfortunately, it hasn't been shared yet. Look for it in the pages of Decahedron Magazine in issues to come.
For now, all I can suggest is to re-skin an ability belonging to another creature whose rank is similar to the creature you're creating.
