The "You Will Die" Mod

Changes:
Updated to 1.6.4. All world gen items are slightly less common by default. Added mystery mushrooms which gen naturally and are used to craft mystery potions. Added obsidian sceptres which allow you to deconstruct and move pillars. Slightly changed tower design to force player to fight through. Towers have a small chance to spawn made of obsidian, and will have better loot. Towers now correctly spawn in the nether. Added two commands, /weaponKnowledge, and /creatureKnowledge, which allow you to keep track of the new weapon/mob kills system, which provide bonuses based off kills with/again specific weapons/mobs. Added two new achievements involving kill tracking. Added a couple active blessing abilities, which can be used with k by default. Tweaked and added a few blessings. Added quite a few new option in the config. Mob health by level is now % based, rather than a flat 5 per level. Bugfixes!
