The buff to Frightened makes Menacing Attack really OP. They should only get a debuff but now they are fleeing, losing actions and drawing AoOs from everyone.
Prone also ends concentration in BG3 on top of taking away your action unless they fixed that. Doubt it.
They really need to get this stuff right. These are basic things that they should have right at this stage, a full year into EA.
The new homebrew conditions they just added are making my head spin. It's way too much clutter.
