There is some bugs here, various creatures react differently on this invisibility, eg: bees find me anyway wherever I stelth or visible, they smell me? - I don't know, wander why dogs don't smell me :) Moose & Goose boss got dodge chance like 100% so I loose 50 sanaty every attack. Didn't test all creatures but I think some of them get asskick with success backstab even if they moving or in combat like spiders but it seems contrary to a playguid.
