-Herbalist/Servant-
Was called servant in other Elminage, but herbalist are basically the same, they have a bags and you can brings quite a few potion,antidote and other items in it. At the end of each turn, they'll use items to recover the party hp/ailement. What's new though is you can find herb in dungeon and mix them to make potion. They have other items like black tea or those wooden/silver bank they can use but I haven't played them much. I think they have the 'special resistance up %' too, which increase their ailement resist
