Version history

Version	Changes
0.3.0	Cluster Grenade: Primary Grenade Attack Damage is now 299-490% at Gem levels 13-20 (previously 199-327%). Mini Grenade Attack Damage is now 174-286% (from 137-225%). Now Fires exactly 18 Mini Grenades in a nova (previously 14), and Mini grenades are fired over a ~17% increased radius.

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. Cluster Grenade's Mini Grenades Explosion Radius is now 1.4 metres (previously 1.2 metres).
0.1.0	Introduced to the game.
