Jainus highly resistant to all types of damage. Only Clara (Ally), Dagus (Ally) (appears turns 2 & 3), and Senala (Ally) (appears turns 4 & 5) will deal significant damage to him. All allies have 0% skill boost and pincer-only skills, so always include them in the pincer and save a few powered points for this battle. Characters with Frequency boosting skills may also help increase the chance of activating their skills, but are not necessary.
Trivia[]
The non-boss version of Janius that appears in Battle 12D is a unique "enemy". He cannot be pincered or harmed by the player and his attacks only deal damage to other enemies.
