Demonic traits

Demons include devils, fiends, daemons, succubi, and more. Demons are usually unique.

Demons have the Evil virtue and can automatically sense Good within 5' per point of INT. They also have truesight.

Demons are ancient and immortal and cannot be killed. Destroying a demon banishes it from that realm for 99 years.

Demons are immune to fire and heat damage. Demons are immune to weapons which do not do holy damage or which are not made of silver.

A demon can use all its actions for the turn to possess a victim within 5' per point of WIL; to do so, it makes a MAG mental attack.

Demons can cause seeming accidents which do their natural damage. This is a LOG attack with a range of line-of-sight.

Any sentient or super-sentient creature can sell its soul in the presence of a demon. Doing so merely requires the creature to make a clear, non-coerced agreement, either verbal or written. Selling one’s soul to a demon is an irreversible diabolical pact and gives the seller the Evil virtue.
