Red dragon (summon)

Red dragons are the most covetous of all dragons. Exceptionally vain, they are forever seeking ways of making other creatures pay them tribute.

Special abilities
This red dragon has 30/+3 damage reduction and 100% immunity to fire damage, but a 10% vulnerability to cold damage. It is immune to fear, mind-affecting spells, paralysis, and sneak attacks, as well as having a spell resistance of 22 and permanent true seeing.

This creature can use its aura of dragon fear once per day and its fire dragon breath three times per day. In addition, it can cast dispel magic, flame arrow, and Isaac's lesser missile storm each once per day as a spell-like ability at caster level 15.
