no idea if its an error but it would be possible for him to have the skill to protect himself, while carrying the enchantment of the same name in his body slot which he can use on another hero of his choice.
so either he simply has the skill (no misprint then) or he starts with the enchantment in hand, then its a misprint.
and I took it as the second option. starting with that at blue is just too OP.. so we decided that he started with the spell; like the goat lady start with hellgoat
(though thematically I can see that they would make him just have that ability. After all have you seen that guy? lol)
