Version history

Version	Changes
0.2.0	Archmage now causes Non-Channelling Spells to Gain 3% of Damage as extra Lightning damage for each 100 maximum Mana you have at all Gem levels (previously 5-6% at Gem levels 14-20). Non-Channelling Spells now cost an additional 6.7-6.1% of your maximum Mana at gem levels 14-20 (previously 5.35-5.05%). Quality now provides 0-10% reduced Reservation, instead of granting Non-Channelling Spells Gain 0-2% of Damage as extra Lightning Damage for each 100 maximum Mana you have.
0.1.0	Introduced to the game.
