Heya, the official description of Blood Surge is this:
What is Blood Surge?
Blood Surge is an effect that procs after you utilize your Bloodborn Spell
so what exactly counts as “utilizing”? Do i have to click the UI element below my generals portrait? What about a spell I got from Alcuin Loremaster or Twilight Sorcerer? If these work, does it also proc from opponent’s BBS?
