Version history

Version	Changes
3.17.0	Removed the Prophecy mechanic from the game, and moved many of its rewards to other content. '''Iron Heart''' has been renamed to '''The Iron Fortress'''. It no longer has "8-12% Chance to Block Attack Damage" or "Cannot Block Spells". It now has "+1% Chance to Block Attack Damage per 50 Strength", "Chance to Block Spell Damage is Unlucky", and "+60-120 to Strength". Existing items are unaffected by these changes. The old, fated version of page=The Iron Fortress (fated) can no longer be acquired.
3.5.0	Added 3D art.
3.2.0	Iron Heart can now able to be fated into page=The Iron Fortress (fated).
3.1.0	Iron Heart is introduced to the game.
