it will work for a while, since the Greater Heal likely can sustain many injuries in one go, so she'll likely be able to switch to Magic Attacks after a Heal, but they will soon hit the wall, especially when they encounter some sorta physical resistance/immunity enemy and dear Sage won't be able to do both roles at the same time.
guess they will still rather stick to it not trying to get MC back and by the time they realise they require him, he's gonna be a One-Man-Show himself, not requiring their roles at all.
i at least hope these 3 idiots won't loose one..
Lol we don't need to wait for long as the goddess and kaito San(extra member join for fun) said...
They can replace hero with martial arts or grand mage but they can't survive without a priest or saint in higher level...
Also sage is mixture of little saint magic and more great mage so basically she is cutting her own strength if she continue down healer...
As it not only cost huge mana for a single spell it also need timing to cast..!
While mc have 2 role one saint where his heal is op and he have magic power as compensation for not having any other skills...
And other one is great dark mage who have offensive power...
Combine it both he is unstoppable...!!
It's like the God of that world didn't have other skill for healers as they level up dead slow so they gave magic compensation so they can heal more...
But it's become advantage to mc now...
Black kite saint sama nice name
