Lexi alone was enough to deal with the horde of goblins and small hydras. Unless she runs out of mana, those monsters won't be able to break through her barrier or surpass her in martial skill and spellcraft.
In this world, while classes and roles existed, no one was actually dedicated to a single one. Fighters, rogues, wizards, barbarians, clerics, paladins, and more, some are damage dealers, some casters, and some specialize in healing or scouting. Still, it was generally known that it was bad to focus on only one thing.
Many monsters are intelligent and capable of picking targets, so in fights, a dragon would prefer to kill the healer first, then the wizard, and lastly deal with the damage dealers. A healer or wizard who can't run, fight, and hold their own won't survive for long in this world, and neither will the damage dealers who can't heal or support themselves with their own spells or items.
