I think this was reported before, though I don’t see it.
Character talents obtained from shrines on Holseher’s Map don’t seem to work at all but do work when obtained from random divine boon shrines in a map.
I don’t think I ever had a talent work when I bought it from a shrine on Holseher’s map.
Even worse, ledges. Pushing is such a survival related reflex I can’t avoid it, and it made me die. This talent should get a rework if only for the fact that it can kill a run if you get it as a random boon. Lots of ledges in the citadel of eternity
