Commander Niall
Commander Niall rules the frozen battlements of Castle Sol in the Mountaintops of the Giants. He is the veteran leader of an army without a nation, an old man with a prosthetic leg who calls up the spirits of fallen knights to fight beside him.
He is one of the tougher optional bosses in the base game, and he guards something you need if you want to reach Miquella’s Haligtree: the left half of its secret medallion.

How to beat it
Phase 1. Niall calls two spectral knights, one with a sword and one with a halberd. Killing one of them early makes the fight much easier. Use a spirit ash or summon to keep Niall busy while you deal with the knights.
Phase 2. When the knights are gone or Niall gets low, he starts using his prosthetic leg: lightning kicks and frosty stomps that create big blasts around him. Keep your distance when his leg glows, then go back in after the blast.
Lore
Niall traded his leg for a prosthesis to save imprisoned knights, and those knights became his army. He has no nation left, but he still guards what his master left behind.
