We've released the Hotfix 0.2.1a - this fixes 2 major issues found by community members:
Fixed Decrease Charge Runes
Now, decrease charge runes work much better together - 2 epic runes will be more effective than 1 epic and one rare, like it is expected.
Additionally, we've fixed an issue that caused multiple Decrease Charge Runes to actually increae the charge costs at some point.
Fixed Orb Overflow Glitch
We fixed an issue that caused a possible overflow of Chargecosts, causing them to go negative, enabling unlimited charging.
Big thanks to Ryan is not amused for finding these issues!
