She mainly casts spells like Blizzaga and can inflict status ailments like Silence. She has a weak water-based melee attack, but she rarely uses it. Defeating her and Rolan rewards the player with the Storytellercrown, and 3-4 Diamonds.
Since Rekoteh and Rolan mainly cast spells, it is a good idea to have someone with the Mirror, Magic Thwart, or Mystro ability. If the party has already obtained Lux, it's recommended to use it since it will increase the party's max health for the battle. Once the party has have Lux and Mirror, Magic Thwart or Mystro up, they should focus on dealing damage and renew the buffs when the effect expire.
