Ragnarok fire raid boss isn't a real challenge for a water team.

The strongest bosses in the futures are thunder, who triple hit you on spell and not normal hit. Due to type-disadvantage you won't able to survive with a full SSR water team, if you don't own a debuff team with 40+/40+ down at least. If debuff misses, then have fun.


So you need at least a 2. team to cover the weakness-type.
