Summon/Portal Effect Table

When you cast a spell that is marked as being a Summoning or Portal spell roll d100 plus the spell level squared on the effects table. Any effect on the table is considered hostile. Most will attack anything they can. They likely kill the weakest creatures first. If they cannot tell they attack the closest creature. According to Demon Lore, every time a demon kills a creature, they become more powerful. 

Note: I also created and use a tableSmith table
