Trool Academy (LV81) on Ga Ga Island.
Each Trool starts with a LV4 Warming Up buff. They will not take any damage until Warming Up is removed. Takes 3 hits to remove it, use low costing attacks to get rid of it quickly.
Trools have another buff called Trool Rage. everything time they take a hit, they swing out with a short-range cross-pattern AoE damage.
Trools tend to throw sand into people eyes, reducing range to minimum.

Celestial Strich Dungeon in Pabong Field, Brakmar.
All striches have very high resist, high dodge and a 20% chance to completely dodge an attack. To remove the resist, a person must lock them first, then on the strich's turn, it must move a space away. Striches have an egg-laying ability that will automatically move them 1 space away, this will not count as a lock-break. The resist removal won't happen there.
Successfully attacking a strich will increase a person's lock stat.
