Commander O’Neil

Commander O’Neil stands in the middle of the Swamp of Aeonia in Caelid, still waving his flag on a battlefield his lord left long ago. He is a veteran of the battle that turned the swamp into a lake of scarlet rot, and the rot has not been kind to him.

He fights with a heavy standard, scarlet rot attacks and a war cry that calls spirit soldiers to help him. For many players he is the first boss that really tests how well they deal with rot.

Drops
Commander’s Standard
Unalloyed Gold Needle
Weaknesses
Fighting from the edges of the swamp, or on Torrent, keeps the rot in check
Resistances & immunities
Many attacks build up scarlet rot

How to beat it

Bring cures for scarlet rot, such as Preserving Boluses, before you go in. The swamp water itself causes rot, so fight close to the edges if you can, or stay on Torrent.

O’Neil swings his standard in wide arcs and plants it to summon spirit soldiers. When he raises his flag and lets out a war cry, back off and deal with the spirits or wait them out. His rot slam leaves a red cloud, so step away from it.

Lore

O’Neil wears the same armor as Commander Niall of Castle Sol. He fought in the battle between Malenia and Radahn and stayed long after his side had left.
