The developers of the isometric Action RPG December have published another trailer dedicated to active abilities. This time, you can see two electrical skills: Lightning Spark Shot and Charge Release.
Like other abilities, they can be modified using runes. Some of them give not only positive effects, but also negative ones. For example, one reduces the number of projectiles fired, while reducing the damage from each of them.
