•Her 1st skill strips.
•Her 2nd skill Cleanses and grants a shield on any ally. 
•Her passive heals every turn and reduces harmful effect time on your team!
•She has good base speed.

•She has the lowest base HP of all the Mermaids. 
•Monsters like Tesarion can oblivion her, dropping her usefulness drastically. 



GB12 (6/10): Tetra is good for keeping your team alive awhile also stripping the ATK buff in Giants B12.

DB12 (7/10): She serves a similiar role in Dragons B12 as she does in GB12. 

NB12 (4/10): She can be used here to heal your team and tank the damage in Necro B12 if your team is struggling to survive.

SF10 (0/10): She is not recommended in Steel Fortress B12. 

PC10 (0/10): She's not really useful here since you want DoTs team or nuke the boss as fast as possible in Punisher Crypt B12.

ToA (2/10): She isn't recommended here since you want CC teams to farm ToA. 

Rift of Worlds (8/10): She is a great front line tank that heals every turn in R5. Make sure she has high resistance to reduce the odds of being oblivioned. 

Labyrinth (3/10): Tetra can be used in stages if your team is struggling to survive.

Dimensional Hole (6/10): She can be used the star limit or elemental limit stages.

Arena (7/10): She is an excellent monster for sustaining defense teams. She isn't recommended for offense as you need AoE cleave teams to farm arena. 

Guild Wars (9/10): Tetra is amazing in both offense and defense. She overall just makes your team hard to kill. Pair her with Theomars and a reviver, and that's a tough team to beat!

RTA (8/10): She shines in RTA since she is difficult to kill. She heals every turn, grants shield protection, and strips allowing you to defense break when possible to deal big damage.
