Your favorite biome mod is getting an upgrade!
While playing Biomes O' Plenty, have you ever noticed that some biomes just... need some more life? Well, I have! And you too apparently since you're here! This mod adds in a couple of mobs (with useful resources) that fit into the more magical environments of BOP that lack fitting vanilla mobs.
Mobs So Far:
Crystalline Chasm (BOP) -
- Crystalline Slime - This fella hops around the crystal caverns, and with its rose quartz spikes, it has good protection from the elements. Don't worry, as these slimy foes don't split on death, although the tradeoff for such a convenience is increased health and thorns damage to anything that hits it. On death it drops Rose Quartz Shards and Rose Gelballs, craftable into a Rose Gel Block, which functions as another slime block type, but one that deals damage when you move on top of it.
Visceral Heap (BOP) -
- Jawbreaker - This gargantuan set of dentures is mad and out to chew you up and spit you out if you come onto its fleshy turf. With chomping hops and a deadly charge attack (you can stun it when it charges by using a shield) this beast is not to be messed around with. Its teeth, however, are a good reward for their challenging defeat, as they can be crafted into a number of items. Who knows, a jawbreaker may even drop something that isn't a tooth every once and a while ;)
More mobs to come in the future!
