Ritual Site

Ritual Site is the second stage in Episode 6: Laharl's Challenge in Disgaea: Hour of Darkness.

Story
Laharl and the group meet Sardia, the demonslayer. She claims to have killed over 2000 demons... or was it under 2000? Her sword can split earth asunder... perhaps. Laharl gets upset and fights her.

Strategy
She's alone. She's level 24. One of these things will matter more than the other. (Spoilers: it's her level.) She has a bevy of spells (even if most of them are buffs) and some decently-leveled Sword skills. Clustering up will result in spells to the face. (Spoilers: not her face.) Gang up on her and utilize chain attacks for the bonus; whomever gets the kill will get a nice pile of exp.
