So at 1:28 Jabber gives poision to Myz, it says it is memorised. The video shows that Myz has that ailment.
He uses his special and at 1:44 I check the opponent hero (a paladin) and he has been given Bera’s poision and not Jabber’s poision.
I assume that Myz had both poisions applied to him, and they overwrite each other. But should the most recent poision that was memorised not be the poision that is cast? Am I missing something obvious?
