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.
