To begin: I asked support and they didn't help (who would expect that, huh), so maybe I'll have more luck with the player community, which is apparently the only reliable source of info about the game... Now, the issue / question:I can see absolutely no difference in damage with and without Forceful Persistence train on Herald. Thre is no notification icon for it (like Hardening Presence or Steadfast Rejuvenation have), and the damage values of attacks remain unchanged with an upkeep skill (Embrace the Darkness, Vengeful Hammers, or anything else) activated. The description is absolutely terrible: there's no skill that has type Upkeep, so I have to assume that these are the ones that deplete Herald's energy (like the ones I mentioned above). But... What are Herald Skills??? Facets? These, as described on wiki, provide no boost at all... So, does anyone have any clue how this trait works, or rather - if it works at all???
