Parasol Field is the fifth stage in Low Tide Beach.
Teacher Bears are normally weak, but his massive strength magnification gives him an attack power of SIXTY THOUSAND. Twice the health of a max level Bahamut.
While Teacher Bear has pretty much the highest damage out of any enemy encounter in SoL thus far, he only has 180,000 health on 1-star difficulty. A fairly leveled Bahamut can take him out in just a couple of hits. Keep him well-protected, and you will breeze through this level.
