Zaltys is a reasonably strong foe to overcome when encountered early, but confrontations with it later on become trivial despite its increased damage output and HP from Day 6 onward. If Lightning is within close range it uses physical attacks and Tail Hammer. When it turns to attack with its tail, it is possible to attack the tail and chop it off. It uses Stampede to knock Lightning back and interrupt her current action, and Blaze Burst is its ranged attack, blowing a burst of fire at Lightning.
It can be staggered with magic attacks, and the head can be staggered by striking it with physical attacks. The head droops when the body is staggered to bring it to Lightning's normal attacks' reach. Zaltys doesn't absorb fire, but is immune to it.
Beat Down attacks from a schema equipped with a spear will automatically target the head, resulting in a stagger that causes Ice-elemental attacks to deal double damage. The player can also target the head manually by blocking or evading its Bite attack, and countering with a hard-hitting strike of their own. Its Tail-strike can be blocked and followed up with Beat Downs to sever the tail causing the monster to recoil, allowing around ten seconds of free time to attack its prone back, which will also deal double damage or even more with the auto-ability Blindside.
