Demon Hide

You touch your minion or familer with your holy symbol
and invoke the horrid words of the lower planes. A fiery glow
spreads across your servant's skin, leaving it with a deep red
luster
The creature gains fire immunity and cold resistance for
the duration. As well it can make a ranged spell attack against
creatures within 120 feet using your spell attack bonus
dealing 2d10 fire damage.
If the minion has a melee attack it adds 2d6 fire damage to
that attack.
