I havent gotten quite that far, What I did was install the mod using it's built in injector, then used Meta Injector to check what files got patched. Then I extracted them all with paz_browser_1.4b, put them into files_to_patch folder, restore backup with meta injector (back to stock) and use meta injector to inject the files manually (let the program decide where to put them.
The files injected are:
Damage does show up, and the radar works normally, you can see other players' HP *after* they take some damage, and you can see enemy health bars above the enemies even without knowledge, but the main health bar at the top of the screen works normally (no knowledge = full hp bar with color change). Also player and monster levels both show.
It also breaks some UI parts, though they're pretty minor/rarely used
It works, I mainly want just damage, but I'm still experimenting what I can remove to have *only* health bars and damage. I'd even take *just* damage display with nothing else: being able to see when and how often I'm missing, how often I get critical hits is absolutely helpful.
