The Rotten Crystal Spear is a Spear in Elden Ring. It only turns up late in a run, in Elphael, Brace of the Haligtree.

The Rotten Crystal Spear is fashioned from pure crystal and festers with scarlet rot, while the magic wreathing it keeps its attack scaling with Intelligence. Putrid Crystalians in Elphael, Brace of the Haligtree drop it at an 8% base rate, with a pair in the room next to the Elphael Inner Wall Site of Grace. It deals physical and magic damage and builds scarlet rot with every hit. It cannot be infused or buffed, and dual-wielded as a pair it attacks faster than many other weapons' light attacks, so it suits a Dexterity build focused on rot.

Skill

Charge Forth costs 16 FP. The wielder lowers the weapon to the hip and charges forward, carrying the momentum into a powerful piercing thrust. Holding the button extends the charge to cover more ground before the thrust lands. Only the final thrust can be parried, and the long reach makes it a fast way to close distance on a distant target.

"Quickly charge forward with the armament at the hip, carrying the momentum into a thrust. Hold to cover a greater distance."
