I know Vlad is not terribly useful. But because he was the first seasonal Hero I received, I leveled him anyway and sometimes use him in wars.
And tonight I discovered that when Field Assist heals someone he’s bitten, HE GETS HEALED TOO!
This would likely work with Valeria too, but I don’t have her. Not sure about Victor.
The highlight of my evening.
ETA: He’s slightly less useless in cleanup because of his Very Fast mana. One purple match down an empty column and he bites again. Go Vlad!!!
