now you have their attention

step 2:

Read this spell out loud, walking around the Pentagram you've made with the candles

Pay close attention to all the details.

This is enough to summon 3 Exogenous Demons and 2 Endogenous ones.

now...

Please pay close attention my friends...

To summon the first Exogenous Demon, use this spell:
