# [Refraction of Ilvaash](Rules\Source\bestiary\aberration/refraction-of-ilvaash-pabtso.md) *Source: Phandelver and Below: The Shattered Obelisk p. 197* Ilvaash was formed from the remains of the mind flayer god Ilsensine, the God-Brain. When Ilsensine left the Far Realm to establish a divine domain elsewhere, pieces of the God-Brain sloughed away and awoke to sentience. This is Ilvaash, the Dissonant Psyche. The refraction of Ilvaash wields only a sliver of the godlet's power but is nevertheless a formidable foe. ```statblock "name": "Refraction of Ilvaash (PaBTSO)" "size": "Huge" "type": "aberration" "subtype": "mind flayer" "alignment": "Lawful Evil" "ac": !!int "11" "ac_class": "natural armor" "hp": !!int "199" "hit_dice": "21d12 + 63" "modifier": !!int "0" "stats": - !!int "17" - !!int "10" - !!int "17" - !!int "23" - !!int "20" - !!int "22" "speed": "10 ft., fly 30 ft.
