To the winged slime,
Rather than bash him, I suggest you spam your electricity magic on that damn idiot healer. Because that's the only way to kill him.
Sincerely,
An annoying reader.
The main strong point of a healer is their abilities to heal, not their abilities to dodge roll any incoming attack. If he say, "I'm a healer, a good and decent one.", he may already got many invitations to the party. Especially, he also had a shield magic and it's pretty OP. Of course, many party will want him.
