Shove, pig heads, dipping, highground advantage, backstab, disengage as a bonus action before patch 5, OP consummables, hide exploit, eventually stealing merchants, throwing ennemies... This doesn't require any rest.
How often you rest just change a the difficulty a bit and nothing more.
Well granted but if you want to do , let's say, the entire goblin camp without resting it might prove a bit difficult. Not impossible, but it will be tedious to deal with certain fights without your spells/abilities. Or rather borderline silly to the point you will realize you're cheesing the game way to much.( For those who didn't watch the LARPG thing, the first thing they do is open a chest with A LOT of cheese ;P ).
Also I'm replaying BG2 :TOB and it's kinda insane how often they made encounters where you can't sleep in between the fights. Announcing explicitely beforehand : Hey, you won't be able to rest. So becareful.
And all those " no rest" encounters were borderline easy cause they didn't want you to get stuck forever.
I can't wait to play this patch and see how this plays out. Would be huge to see Larian succeed where bioware failed.
