I have a sneaking suspicion this passive doesn't work. It is supposed to give 1 additional ultimate when activating any earthen heart ability. I haven't run any thorough tests, but I'm pretty sure that this does not enable you to generate ultimate out of combat by simply spamming Igneous Weapons or one of the other non targeted earthen heart skills. So does this mean it only affects earthen heart abilities that deal damage and therefore already generate ultimate? I'm not to clear on what the basic rules for generating ultimate are, other than you can do it in combat by "playing well."
