Been able to recreate 3 instances of ooze AoE damage continuing after the skill is disabled through lack of mana. I can't pinpoint the cause exactly but it seems to happen when you're using other skills/stunned when your mana runs out.
When it happens the ooze button shows the un-activated icon and there is no mana drain so mana regenerates normally back up to full whilst the damage continues. I haven't been able to catch if the attack speed debuff is still applied to enemies yet though. Anybody else had this happen and got any insight into exact causes?
