You can see “Overload” as follow: X charge cost per cast per target
We will investigate if we need to change anything regarding that mechanic
It seem the ability description isn’t accurate indeed.
Overload cast the ability “Zap” at the cost of 10 charges. Zap itself cost 0 charge, it is the Overload ability that cost charges to activate.
Description does need to be corrected. Thank you for noticing this issue
Either unstable should cause multiple lightning blasts + cost increase, or say that it isn’t compatible.
If you can provide a short clip of what you see, it would help greatly. Testing did not show the issue you are describing. I’ve tested with a cold conversion and was able to see multiple casts of “Cold” blast.
Important note:
In the future, please create an individual post per bug. It is much easier for us to track and investigate.
