|This high-investment set seeks to make Xander as impenetrable an enemy-phase fortress as possible.
Siegfried is a must, as the ability to counterattack at any range makes Xander excellent at tanking and killing all manner of threats.
Swap or Reposition gets more fragile allies out of harm's way. Swap is best used in tighter spaces.
Bonfire and Ignis both scale off of Xander's incredibly high DEF stat, supplying an inordinate amount of damage whenever they activate. Bonfire is best used for enemy phase killing, while Ignis gives Xander nuking capability on player phase.
Steady Stance 4 grants him a blisteringly high DEF stat on enemy phase as well as preventing enemies from charging their specials- a very important thing to do when it is almost guaranteed that Xander will be doubled.
Quick Riposte 3 allows Xander to fire off Bonfire whenever he is doubled and has high enough HP, making him exceedingly dangerous. At higher merges, Bonfire can easily do 20+ damage whenever it activates.
Though Xander wants to receive buffs, it is also wise to make sure he gives them to his allies. Any nature of Cavalry buffs works, but Hone is best used to make player phase allies all the more dangerous. Panic Ploy can be used instead to give enemies who rely on buffs a very hard time.
Finally, the Warding Stance seal makes it so that Xander can patch his mediocre RES against both mages and dragons- a very important factor in a meta that is still driven by Bold Fighter dragons such as Duma and Legendary Tiki.
