History of Headstone

Headstone is a weapon trait that spawns a Stasis crystal at the target's location after a precision final blow. It debuted in Season 15, Season of the Lost (2021), as the first Stasis perk on Legendary weapons, and works without running a Stasis Subclass.

Details

• Crystals are full size against major combatants; minor and weaker enemies produce a medium crystal.
• Crystals can freeze nearby targets and be shattered, so they combine with Stasis Aspects and Fragments such as Whisper of Shards and Whisper of Chains.
• Creating five crystals in a short window triggers a brief cooldown (about five seconds, per light.gg search data).
• Fractethyst cannot roll it, since pellet shotguns rarely land precision kills.
• Example weapons: Vulpecula, Peacebond, Reed's Regret; it also appears on Exuviae.

The Silver Contrail article calls the freeze range limited and unreliable for crowd control.
