Noctis is an Earth bruiser limited-time unit from FFXV collaboration. With the power of the kings, he has a wide arsenal of weapons that provides him with a lot of utilities, which makes him a pretty complicated unit to work with due to having so many options.
In terms of damage, he doesn't have any form of penetration from his kit, but he can still reliably deal damage since he can reduce DEF and 3 attack type resistances, as well as having 3 different attack type options (including a typeless + elementless attack from Power of True King that scales with MAG). Main job as sub job also provides a Strike attack, while Ninja has Shuriken for Elementless, and Doton for typeless.
He's also surprisingly tanky since he has decent HP and gets a good amount of resistances through 2 passives and another +20 magic resist from Oath of Salvation, but his main job skills also give him DEF and Protect.
