Xander

Xander’s Sword: The Murasama. A blade with the essence of the chaos god of Calamity empowering the weapon
Xander’s Shield: The Lord’s Grace Shield. An unbreakable shield gifted down upon Xander by the Lords.

Xander’s armor: Solar Flare Armor, yeah, I can’t sugarcoat it, Xander’s armor is quite literally just Solar Flare Armor, Armor made materials capable of absorbing power from the most violent of celestial bodies.

I used fanart of Terraria’s Solar Flare Armor since I think that best shows Solar Flare armor.

(BTW neither of the Solar flare armor images are mine and I have no idea where they came from. I saved them both from Pinterest.)
