Imperial Knights Lea
Route 1 alchemy companion who joins after the Protea cathedral sequence.
Lea (レア) is a Route 1 companion who joins after the Protea cathedral sequence. She uses alchemy to craft potions and provides offensive support during her brief time in the party. Players often overlook her because her join timing puts her between two major dungeon clusters, but her Poison Through skill is one of the most powerful early-game poison effects available.
Profile
- Japanese name: レア
- Voice actress: 乙倉ゅい (Otsukura Yui)
- Role: Alchemy / flex attacker
- Join timing: After clearing the Protea cathedral underground

- Route availability: Route 1 only
Skills
Poison Through (調合術：毒通過)
Lea’s signature skill. Requires poison grass and an empty bottle from inventory. Creates a poison-based attack that deals damage over time. This is one of the few sources of sustained poison damage in Route 1.
Poison grass can be obtained from:
- Herb gathering in the plant colony forest
- Purchase from herb shops in later towns
- Enemy drops
Combat performance
Lea functions as a flex attacker during her time in the party. She does not have healing abilities, so she cannot replace Lysithea as the party healer. Her value comes from:
- Consistent poison damage application
- Reasonable magic attack stat
- The ability to use alcohol-based items for stat debuffs
Equipment recommendations
When Lea joins, prioritize the following:
- Equippable weapons — Check what she can equip. Her stat distribution favors magic attack.
- Accessories — Poison Rings complement her poison-focused kit.
- Cards — The card tier list notes that generic stat-boost cards work well on flex party members.
Unequipping before departure
Important: Lea leaves with Lysithea after the catacombs. Unequip her gear before the catacomb exit scene. This is a common mistake — players forget and lose mithril-grade equipment.
The checklist tracks equipment on departing party members.
After departure: mercenary access
Once Lea leaves, she registers as a guild mercenary. You can hire her back for approximately level × 100G. She is useful for:
- Filling the fourth party slot after Tear leaves
- Providing poison support for late-game bosses
- Card carrier for status-null effects
