I am experiencing the same issue, Offline Tools won't open. I tried reinstalling the latest version, but the result is the same. Everything worked fine until a couple of weeks ago. Offline Tolls version: 0.6.4 Mod version: 2.3.3 Windows 10
How do you manage to kill Xazax and Astrogha with this setup? The minions just hit Astrogha's totems so it heals every time. As for Xazax, I have tried with Rathma and VK. They damage Xazax over time but the screen gets too crowded with penitents and they eventually kill me.
