Thanks , there are a lot of other useful Features to edit in this file , like FOW Uncover range etc.
what does the FOW Uncover range do?
Found an easier way to hack experience from monsters, change to:
MP_experience = {1000000,1000000,1000000,1000000,1000000},
My 11 lvl got 2000 xp from killing one 6 lvl, and 4k xp from killing 8 lvl.
your game did not crash as a result, are you still playing with this changed?
