This spell must be cast over the course of seven hours in a single night. In that time, you concentrate on an ancient, nightmarish ritual that fuses shadows and flesh into a banderhobb, a monster resembling a vile, bipedal toad. The flesh can come from either a single large creature, four medium creatures, or 12 small creatures.
The banderhobb is friendly to you but indifferent to everyone else. It obeys your spoken commands, moving and acting in accordance with your wishes and acting on your turn in combat. It cannot be healed. The creature may be sent on a mission--such as “attack my enemies” or “bring me the queen.” If it completes the activity before the spell duration expires, it returns to you.
This spell is rare and not freely taught by those who know it. You cannot learn it through normal means. It must be taught to you by an evil spellcaster or found in some other way. If you cast this spell again, any banderhobb you previously brought into existence with this spell instantly melts into a putrid mass of green slime.
* - (flesh from creatures killed within the last 24 hours in quantities sufficient to make a large creature; powdered obsidian worth 1,500 gp, sprinkled over the flesh and consumed by the spell)
