Typo on “on fire” effect from fire arrows.
13m was meant to be 13s also the description.
Its also on most debuffs on foes. its on slow effect it shows “m” instead of seconds.
It is 13 because 2 already passed. And it is m (minutes) and not s (seconds) because it is about in-game time, not real time. It would not make any sense to damage the enemy every 5 minutes real time, it usually takes just a few seconds to kill one
ooooo thanks for letting me know. i’m so used to other games.
It make more sense that the buffs/debuffs reflect real-time, not Hearthstone time.
