Shaula is faced in over two phases with different strategies in each. During the first phase, Shaula focuses on inflicting status ailments or other secondary effects on all its attacks, while on the second phase it focuses on higher damage output. Consistently between both phases, Shaula employs both Physical and Magic Damage, single target and to all units.

During the first phase, Shaula uses these abilities:
*Poisonous Hex: Inflict poison (100%) on one unit. Physical damage (4x) to one unit. Decrease DEF (30%) for 3 turns to one unit.

*Blood Feed: Magic damage (10x) as HP drain (100%) to one unit. Magic damage (0.8x) as MP drain (80%) to one unit.
Shaula begins the battle with a preemptive strike using Poisonous Hex, Kodoku and ending her turn.

==Strategy==
The battle is not too difficult but the player should come prepared with immunity to status ailments, including Charm and also Tanks that can both provoke damage and Cover the party.
Due to the preemptive strike it is likely that 2 units will be killed at the start (or one if they target the same unit), as such it is recommended to place non-relevant units at the main party (mostly damage units) and keep the tanks, healers, support units on reserve. A good idea could also have a unit with 100% chance of targeting so that casualties are minimal and setting up is much easier.
Since Shaula uses both Physical and Magic attacks in single target and all target forms, it is theoretically impossible to Cover all damage, however, the way her abilities work like in a turn basis make it possible to swap between Covers and be able to tank the damage for most turns at least, as there will be a few turns (divisible by 12, but displayed as 11, 23, etc. due to preemptive strike) where both will coincide. This is especially true in 2nd Phase where she will use both at once. 
Therefore offensive stat breaks and defensive buffs are a priority to survive. If possible 50% ATK/MAG breaks and above are recommended, as are stat buffs of 100% and above and if possible with some Damage Mitigation.
Offensive-wise most damage units will do the job, although Wind damage for first phase and Fire damage for second phase is the most optimal. For the former Magic users of Tornado and Aeroja will do the job fine, although Malphasie can also work just fine. For the latter phase, Fire damage is fairly common so most physical chainers should be doable, notoriously Raegen, Hyoh or the like, otherwise the likes of Emperor or Dragonlord can deal massive damage anyway.
For second phase it is ideal that the player one-turn kills Shaula to avoid problems with her multitude of attacks that will be tougher to Cover. Also as a priority her buffs should be dispelled and stat debuffs should be reapplied. ATK/MAG debuffs to all enemies should be prioritized since Shaula is immune to DEF/SPR debuffs and the Arms will most likely remain alive afterwards.
Charm can be difficult to deal with but the likes of Mercenary Ramza (enhanced) have Charm immunity, otherwise Lakshmi at 3★ provides a Charm immunity buff.
Perhaps the toughest part of the battle is delaying the kill in order to use 5 Limit Burst for missions which is better achieved on first phase, or during second phase when only the Arms are alive. Regardless by the time the trial is released there is ample repertoire for damage users that can defeat her quick, but it is the defensive preparation that is of most concern.
