I manage to save spam my way through most of the battles of Act 2 and have come across a battle that appears to be impossible for me to beat even with save spam.
The gith ambush after defeating Ketheric.
Current situation:
*No Shadowheart. Had to ditch her. Won't explain due to spoilers.
*Currently a pure Cleric.
*Party is level 7 right now.
*Did not go through the Underdark because I wanted to roleplay as somebody who didn't want to deal with puzzles even though I know that you can gain access with high perception. At the time wanted to see how far I could go under-leveled and got my answer.
I made a cleric because I found out what would happen to Shadowheart in a previous playthrough but was thinking maybe I should make a wizard.
