There's a lot of things to say about all those "larian's gimmick" but this thread is great and you explain well why one of them is a problem.
We could probably also mention that those un-avoidable (not sure it's a real EN word) surfaces damages has very huge and bad consequences on the concentration mechanic.
It's way too easy to break a character's concentration and this is very frustrating.
A huge +1 for this thread.
Thanks! And yeah, the Concentration system is especially negatively affected by Larian's invasive species, to the point that the use of Concentration spells are on the brink of extinction.
