Old silver dragon

Silver Dragons are regal and statuesque. They cheerfully assist good creatures in genuine need, often taking human or elven form to maintain their anonymity.

Special abilities
An old silver dragon has the usual dragon immunities to paralysis, mind-affecting, and sneak attack, and it has permanent true seeing.

This creature can use its cold dragon breath and paralysis dragon breath each thrice per day and its aura of dragon fear once per day. Additionally it can cast, as a spell-like ability, dispel magic, dominate person, fireball, Melf's acid arrow, phantasmal killer, and slow each twice per day with a caster level of 11.
