I've done a bit of testing with the Bully trait with a new character (an Enchantress) on the latest release. Despite applying the 'slowed' condition on an opponent I cannot generate any additional damage when using 'Staff of Magus' or 'Headvice' skills (actually once did the minimum possible damage listed for the weapon in the tooltip). Is anyone aware of this trait working with spell damage? Perhaps the Bully trait is meant for Melee characters only?
