The weapon's in-game name is Rope and Grapnel, also written Rope & Grapnel. Its upgrade recipe is Rope & Grapnel + White Dwarf = Ghost of Rhea.
Identify Lyssa's hook weapon
Lyssa Revenya starts with Rope and Grapnel. Hooks enter from random edges of the screen, strike points on the battlefield, damage enemies and drag surviving targets. Weaker enemies can be killed by the initial attack.
That means the base weapon already offers control. An enemy being pulled does not indicate that Ghost of Rhea has appeared; the evolved form has a different effect.
Evolve into Ghost of Rhea
| Part | Required item |
|---|---|
| Base weapon | Rope & Grapnel |
| Passive | White Dwarf |
| Evolution | Ghost of Rhea |
- Start as Lyssa or obtain Rope and Grapnel in your run.
- Equip White Dwarf.
- Upgrade Rope and Grapnel until its base form is maxed.
- Open a boss-dropped chest with both ingredients equipped.
The recipe is tied to the weapon and passive, not to reversing the words “rope” and “grapnel” in a search. Check the item shown in the game if you encounter those different name orders.
Recognize the evolved effect
Ghost of Rhea sends Lyssa's former mentor's spirit across the battlefield. The ghost bursts into a cloud of damaging fog.
This is different from the base hooks' dragging effect. Identify the transformation by the evolved weapon name and ghost effect rather than by the presence of any enemy movement.
Check a stalled upgrade
White Dwarf must be equipped in the current run. Its appearance in an unlock list is insufficient, and a high character level does not prove the hook weapon is maxed.
Once both ingredients and the weapon state are correct, pursue a boss chest. A normal level-up offer and a boss chest are separate reward sources; do not expect the evolution simply because your champion gains a level.
