Item	Description

Version history

Version	Changes
0.3.0	Volcanic Fissure: Now creates two branches that emerge from either side of the main fissure. The length of the fissure is now affected by area modifiers. Now has a minimum Gem level of 7 (previously 9). Now has 80% of Physical Damage converted to Fire Damage (previously 60%), and now deals 88-145% Attack Damage at Gem levels 9-20 (previously 84-163%). Aftershocks cannot trigger more than once every 0.2 seconds. Quality now provides 0-20% chance to cause an Aftershock, instead of +0-4 seconds to Fissure Duration. Allied Slams now trigger Volcanic Fissures. Re-triggers are now treated as Aftershocks and will scale with Aftershock specific effects.
0.2.0	Many Skills have had their base damage and/or damage growth per level rebalanced. Most of these changes are not specifically mentioned below as the changes are too widespread. The mana cost for all Attacks, Marks and Warcries has been reduced, most notably at higher Gem levels. Volcanic Fissure now has a limit of eight concurrent fissures on the ground, and the aftershocks no longer erupt other fissures.
0.1.0	Introduced to the game.
