Question about Xandro Bloodrinker

The wiki is of no use because they still haven't updated info on the newer batch of exiles. I saw him the other day in a gorge map and he was making daggers come up out of the ground! Not in a circle like Brutus but ahead of him. What the hell is he doing? It's a miracle I didn't die.

Must be the Ground Slam effect. It shows spikes coming out of the earth with every hit.

Thanks

Xandeo isn't an old exile and he is listed on the wiki.
It was just his ground slam attack that looks the same as the player version
