Crimson Desert Abyss Gear effect that recovers stamina on every successful weapon hit, with no cooldown and no input. Lv 1 comes from Stamina Transference; Lv 2 comes from Celestial Transference, which is exclusive to the Sword of Starlight as of Patch 1.04.00.
The Stamina Siphon is an Abyss Gear effect in Crimson Desert that recovers a portion of stamina on every successful weapon hit. The recovery is passive: it requires no input, has no cooldown, and does not consume Spirit. As of Patch 1.04.00, the effect appears in two tiers: Lv 1 from Stamina Transference and Lv 2 from the new Celestial Transference gear pre-applied to the Sword of Starlight.
Each landed weapon attack credits a portion of the stamina bar back to the player. The siphon happens passively - the player does not press a button to trigger it - and there is no internal cooldown between activations, so a long combo string accumulates stamina back across every connecting hit. This makes it one of the only ways in the game to recover stamina while continuing to attack: ordinary stamina regeneration is suppressed during weapon use, so even slow regen does not apply during a combo without a Siphon source.
Why it Matters
It is the only standard way to recover stamina mid-attack. Most stamina-recovery items and stations require the player to be idle. Siphon is the exception that lets dodge-heavy and parry-heavy builds keep cycling without resting.
It scales with hit count, not with damage. Builds that connect many small hits benefit more than builds that connect a small number of large hits.
It pairs naturally with stamina-thirsty skills. Skills that consume stamina per cast (rolls, parries, charged attacks) become more affordable when the underlying combo is feeding stamina back.
Both gears can be extracted at a Witch and re-socketed onto a different weapon, so the underlying Stamina Siphon effect is portable. Common patterns:
Move Lv 1 to a preferred Kliff or Oongka weapon early in the game. The Lioncrest Manor Hwando is one of the earliest reliable sources of any Siphon effect.
Move Lv 2 onto a build's main weapon late-game. Damiane builds that already use the Sword of Starlight can leave it in place; builds on Kliff or Oongka can extract Celestial Transference and apply it to a one-handed sword they actually use.
Do not stack Lv 1 and Lv 2 on the same weapon. The two gears occupy the same effect family and only the higher tier is reported to apply when both are socketed at once.
