Already used the ingame report feature but why not post it here too.
The skill Runebolt is a 0 mana cost skill. This does work as intendet but in the skilltree if i take the Keynote “Ice Shard” or “Jolting Spark” the skill changes. It cost 3 mana because… well, it shoundt. The descriptive effect works fine but it does not say that it increases the mana cost. The Keynotes that changes all to fire do not increase the mana cost so. Pretty sure thats a bug or you guys forget to write that in the description.
Thanks
