A question or two:

Might I ask for your reasoning for dropping halfies exp penalty to 0? It kinda feels they should have a bit more (like the old 100) than humans...

If I understood correctly, you can now have two (or more) same protections cumulatively, e.g. while wearing a 'resist fire' item you could now quaff a potion of 'resist fire' and have them stack? Or do the additional effects have to be of a different type (like prot from heat)?
