Rakshasas speak Common, Infernal, and Undercommon.
Detect Thoughts (Su): A rakshasa can continuously detect
thoughts as the spell cast by an 18th-level sorcerer (save DC
15). It can suppress or resume this ability as a free action.
Spells: A rakshasa casts spells as a 7th-level sorcerer, and
can also cast 1st-level cleric spells as arcane spells.
Alternate Form (Su): A rakshasa can assume any humanoid form,
or revert to its own form, as a standard action. This ability is
similar to the alter self spell cast by an 18th-level sorcerer,
but the rakshasa can remain in the new form indefinitely.
Spell Immunity (Su): Rakshasas ignore the effects of spells
and spell-like abilities of 8th level or less, just as if the
spellcaster had failed to overcome spell resistance.
Vulnerable to Blessed Crossbow Bolts (Ex): Any hit scored with
a blessed crossbow bolt instantly slays a rakshasa.
Skills: A rakshasa receives a +4 racial bonus to Bluff and
Disguise checks. *When using alternate form, it gains an
additional +10 circumstance bonus to Disguise checks. If reading
an opponent's mind, its circumstance bonus to Bluff and
Disguise checks increases by a further +4.
