Lol I was wondering that myself, would've thought there would be a cap on it, it would be good if there was a unit that could protect them for a while in a normal game
You're talking Avalon. Though I primarily run Flameborn, three units come to mind.
Penitent Warden
Lord Paladin Cadogan
And yes, Royal Alchemist.
Though I generally wouldn't recommend boosting more than once or twice, as you could spend that time attacking and accomplish the same amount of damage with less chance of being ruined by a graze.
