CUBES
Resilience cube for faster reload.
OL GEAR
Basic DPS build: Elemental DMG, ATK and max ammo capacity. Crit can be used as filler lines since she works pretty well with units like Miranda (Treasure).

Pros & Cons
- If paired with Arcana she is a strong shotgun DPS to use on elemental raids. Since most of the damage is coming from Arcana buffs, you can also keep her skills at level 7 and still fully benefit from them.
- Isabel, on her own, it's trash. She only works because they introduced a buffer specifically made for her (Arcana).
- Low damage multipliers for Marked Target and marking system are only beneficial over long fights
- Reducing Full Burst duration for a majority of units is a downside and lowers DPS (this does not apply if using units like Arcana)
