Soul Scream [>>] (auditory, concentrate, emotion, enchantment, mental, occult) Frequency once per day; Effect The irnakurse unleashes an alien shriek of nightmarish horror and pain. All non-evil creatures within a 10-foot emanation must attempt a DC 28 Will save. The irnakurse can.

Critical Success The creature is unaffected, and is temporarily immune to Soul Scream for 24 hours.Success The creature is stupefied 1 for 1 round.Failure The creature is stupefied 1. Further failed saves against Soul Scream increase the condition value by 1, to a maximum of stupefied 4. Each time the character gets a full night's rest, the stupefied condition gained from Soul Scream decreases by 1.Critical Failure As failure, except the stupefied value increases by 2 instead of by 1.

Storm of Tentacles [>>] The irnakurse makes up to four tentacle Strikes, each against a different target. These attacks count toward the irnakurse's multiple attack penalty, but the multiple attack penalty doesn't increase until after it makes all of its attacks.
