The AI animated a Druidic staff. It became a 2/7 creature which still heals 5 HP each turn. Then the AI puts Adrenaline on the animated druidic staff.
No problem, I deal 30 HP of damage each turn. He's at 70 HP already. Three turns and it's over... But it's not: For each Adrenaline hit the Druidic Staff makes, he heals 5 HP.
And I guess that shouldn't be.
Thank Fake God I have a Dusk Mantle.
