The Giant Stone Coatl is the mini-boss in Otami Ruins. It sits on the left of the throne room, guarded by Masks of Death and Rebirth. All of the Animated in the room take the CL of the highest person in the group, so it helps to have a crew who is either all the same level, or caps to the same level. Whenever you defeat a section of the warriors they send out, a Mask of Death and Rebirth will battle you, and if you defeat it, a fire will go out.
The Stone Coatl has a lot of health points, and is immune to the rings Quicksand and Scaredy Cat. It will shoot lasers at you that do a lot of damage, but it will take a little bit of time in between to shoot again. It will also deflect some of your attacks, so hit it with everything you've got. The fireballs and lasers it shoots are short-range, so it is thought that it can't hit you if you use long ranged attacks and are standing at a distance, however you'll get attacked by minions. After the Coatl dies, all the minions die, so it helps if you just go for the Coatl...unless you're close to dying that is...
Stamina is a big problem. Buff up a lot.
