maybe bags of potential could be a drop from the thorium bosses, like the grand thunder bird and the queen jellyfish instead of dropping from normal mobs, because if I used all the bags of potential I got I would have well over a full stack of thorium by now.
also, some thoughts on terrarium items:
first, awesome job making it craftable.
the terrarium sword projectile can go through blocks, I understand that's intentional but do you think the range could be lowered somewhat? it's annoying having it weird up your minimap and break pots you didn't even know were there. maybe it could have the range lowered but the damage/critical strike chance increased to balance it out.
the terrarium hyper discs are too big, if I'm standing next to a block(even if it's BEHIND me) I can't throw them, and I also think they should bounce like the light discs.
terrarium items should give enemies the debuffs longer, maybe for a minimum of 10 seconds. alternatively they could give a new debuff called "Terrarium's Bane" which would lower defense by 20 and deal 20 damage per second(and last 10 seconds at least), because the debuffs aren't really that good IMO.
you should be able to craft terrarium items back down into less terrarium than was used to craft them, so if you craft the hyper discs they could be crafted back down into 4 terrarium or so, because I accidentally crafted 2 hyper discs instead of the cores.
the terrarium pulse rifle should have a chance to not consume ammo.
terrarium(and other) wings should have horizontal speed bonuses so you don't move like a snail.
water walking boots should be able to be crafted or bought from the diver.
could you make the frozen turtle shell craftable? because it's stupidly hard to get it.
the holy aegis is unequipable.
You were correct, though I almost died once. Even with rapid healing the cog lord still saws through your HP.
try the daggers of the bloodlord from pumpking's mod. you will annihilate the cog lord. also, what armor/accessories were you using?
