Star Sabre

The Star Sabre is a weapon that was created by Isaac for unknown purposes, and replaces the Diamond's Edge in season 3 of Adventures in Necrosis. It does less raw damage than other primary weapons from earlier seasons, but is capable of recovering health whenever an attack lands.

History
The blade's history is currently unknown; it was first seen in Season 3 of Adventures in Necrosis, when it was wielded by Isaac. It was first used to battle a group of Witches, although this was mostly unseen; it was later, more visibly, used to fight off a group of Skeletons that had taken over Wizardscape.
