Xenoblade Chronicles 2 brings back KOS-MOS from Xenosaga Episode 1 (2002), this time as a rare blade!
She is an incredibly effective, user-friendly unit that has plenty of passives to keep the driver healthy and safe. Most importantly: her Lv.2 Special is an incredibly potent team heal, letting you turn the tide of battle in her favour!
In my mind, KOS-MOS is one of the "Big Three" Ether Cannon blades. She fits in a comfortable middle-ground, letting her adapt to every situation, in comparison to Sheba and Herald, who shine in particular scenarios.
