Storm Brand is a spell which creates a brand on the ground. While attached, the brand sends beams of lightning damage to the attached target and enemies nearby it. This skill may chain.

Skill functions and interactions

Maximum Active Brands: All brands share a limit of three (3) active brand limit. This can be split between the two brand skills (2-1) or all of one type. Passive skills can increase the number of active brands that are allowed to be active at a time.

Maximum Brand Attachment: By default, you may only have one brand of any kind attached to a single target at any time. Taking the Keystone Runebinder allows you to place a second brand on a single target. Like the Active Brand limit these brands may either be split (1-1) or both the same type of brand.
