Dark Lance

The Dark Lance is a purple, spear like weapon seen in demilogic's new video. It's subject to release in the 1.05 update.

From what the video is showing, the Dark Lance does 24 Damage, and has a 4-6 block attack range and pierces multiple enemies/strikes one multiple times.

This is most likely an item of the demonite tier, due to its mid damage.
