Version history

Version	Changes
0.3.0	The base damage scaling of all player spell and secondary damage skills has been tweaked to scale better in the late game. Frostbolt: Now has a minimum level of 5. Base Projectile Speed has been lowered by 20%. No longer leaves Chilled Ground as it travels. Instead, it Chills as though dealing 120-195%% more Damage at Gem levels 5-20. Projectile now deals 15-23 Cold Damage at Gem level 5 (previously 24-36), scaling up to 144-216 Cold Damage at Gem level 20 (previously 201-302). This change does not affect the explosion.
0.2.1	Added "Barrageable" gem tag.[Undocumented]
0.2.0e	Frostbolt's Explosion radius is now 2.4 metres (previously 1.6).
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.
0.1.0	Introduced to the game.
