Lyra

Overview
Unique Naga. Lyra can be found in cave portal events.

Combat
Lyra has decent Stats with no downsides, with a focus on Magic and seduction. Her skill set is sorely lacking however, with HolyLight to support, Constrict and Entice to seduce, and ExtractMana.

Events
You're given the choice to avoid her, but if you wish to recruit her you'll need to approach her and play along with her attempt to hypnotize you. Doing so will completely drain the Main Character's Mana. Eventually she notices that you're pretending and requests to join your party on your 5th meeting.

You can reject her however, which will land you in a battle against Lyra and her party of Light Spirits. It's a tough fight, but it will get you 5 uses of LightShards that gives +1 to Max Level and 1000 exp as well as full Health and Mana each. The LightShards are significant, as they work on the Main Character. They are extremely rare and cannot be crafted, so this is a great opportunity to get some.
