Ascension Points
From Grimhaven Wiki
Ascension Points can be obtained by killing the bosses: Grolnak the Bonechewer and Razhkul the Frozen in Tavros.
The points are then used in the talent tree in the magical system module to gain permanent buffs on your character.
The first point spent cost 200,000 gp and then each next point will cost 10% then the previous one.
Points spent can be resetted by clicking the 'Respec' button in module but a Respec Scroll is needed for it.
