Defeat Eleonora, Violet Bloody Finger

To complete this square you need to defeat Eleonora, Violet Bloody Finger, the NPC who invades you at the Second Church of Marika, in Altus Plateau. Wait until the "ENEMY DEFEATED" or equivalent screen appears to mark the square.

This enemy only invades if Yura is dead or if his quest is advanced enough, so the fastest way to get Eleonora to invade is killing Yura – which leads to good synergy with Kill 3 friendly NPCs. This square also has synergy with Defeat 3 NPC invaders.

DANGER

Eleonora does not count as a boss.
