Rise of the khltchlands: Dawn Of Death [Parasite Infection]

every armor has been buffed and obtaining them is easier
khltchnite and plutonium can be obtained in many new ways
many recipes have been tweaked
khltchified mobs are more common overall

but most importantly... the mod has a radiation poisoning system now! (dont worry, its not super annoying) basically certain blocks, plants, items, and mob abilities can cause different levels of radiation poisoning that cause minor debuffs. new craftable pills and the 3 armor sets within the mod cure/prevent radiation poisoning, the level armor prevents is based on strength of the armor: ie, chitin armor only prevents acute radiation poisoning, whilst hivemind prevents all levels.
