That's neither a critique nor an idea so I'm leaning towards deeming this a Bug.
Cave Hermit credo repeatedly asks me to study Dark Effigy that is unobtainable solo without purchasing the Rage skill that in w16.1 prohibits passing throuh gates while in combat and therefore is quite undesirable.
There can be arguments:
1. Drop the quest;
2. Trade for an Effigy;
Counter-arguments:
1. The quest appeared several times so it's really unfair compared to all the other credos in their relation to required actions NOT being locked behind such a dividing skill as Rage;
2. Trading would require interaction with a player that, inherent to the trade subject, would most likely have Rage; Cave Hermit credo has "hermit" in it's name; so no, trading is an unfair option as well.
TL;DR
Cave Hermit credo sets up unfair requirement to either acquire Rage or to interact with people with Rage contrary to the very nature of a Cave Hermit.
please fix.
