Mindreading is not really an issue in the base game, as the EXP is scaled to your level, so if you fall behind the curve by mindreading too much, the enemies will just start giving more EXP to get you caught up. However, in the expansion pack (Flames of Vengeance aka the Aleroth chapter) the mindreading costs get absolutely ridiculous at 7.5-22k per NPC, so you quickly find yourself 200k+ in debt and enemies only give 3-4k EXP. Unlike the base game, the enemies DO respawn in the expansion, so you're not permanently screwed, but it quickly becomes a huge grind, and I got sick of it and decided to hack the game instead.

- Open bin\Divinity2.exe in a hex editor (such as HxD[mh-nexus.de]).
- Search for 8B 44 24 04 01 81 90 and replace it with 31 C0 90 90 89 81 90. In HxD specifically, it's Search -> Replace -> Hex-values.

This does two things:
- While mindreading will still show an EXP cost, no EXP debt will be incurred anymore.
- If there's already any EXP debt, it will be reset to 0 upon reading anyone's mind.

Also, while you're at it, you might as well apply the 4GB patch[ntcore.com] because the expansion pack is quite crash happy otherwise.
