Thanks a lot for making this, it does make everything that much easier; being able to kill a level 40 dragon at level 1 is pretty funny.
But the Inifinite Health option does indeed make the PC and all NPC's almost immortal to everything, the only exception I've seen so far is when I'm at a high level advantage, such as being 30+ and killing level 15 or lower enemies. Although, the upside to that issue is that you can never fail any escort quests because your allies/escortees will never take any damage.
I just wish that this had more options to it, such as; more xp gain, more gold drops from enemies, free attribute/skill points or being able to set to specific numbers, and things like increased movement speed.
Honestly, having increased movement speed would be the biggest improvement to this trainer, if it can be done, because of the size of this game and how slow the player character moves for the first 50 levels or so.
