Pro Mode

Pro mode is an alternative to expert mode. With different reasons for being harder and different boss drops, along with an entirely exclusive boss. Fighter AI enemies now will go into "shield mode" where they have insanely high defense(9999), and regenerate a third of it's health. Flying AI, bat AI, and demon eye AI will go through blocks. Slime AI will hop much faster and are immune to knockback. Caster AI projectiles are homing. Plant AI enemies have 5 x their original reach, and can attach to any block in their range. Swimming and jellyfish AIs are much faster. Hovering AI enemies have double their original stats(except for defense, only increased by half). Tortoise AI enemies have 9999 defense while spinning. Spider AI inflict poison pre-hardmode, venom hardmode. Mothron eggs have 30 defense. Old one's army enemies have greatly increased speed. Defense, lunar pillar, and lifesteal are the same as expert.(note to self: finish later)
