Excalipurr
Excalipurr is a high level grotto boss and a member of the Beast family. He attacks twice per turn. When defeated, he yields 70000 EXP. His arsenal of moves includes:
Basic Attack: Nothing special.
Quick upward slash: If it connects, knocks the target off their feet.
Disruptive Wave: Dispells all magical effects on the party and returns their tension to normal.
Multislash: Hits multiple targets, chosen at random. Each hit is less powerful than his basic attack, but if all 4 attacks hit the same character, they could be in trouble.
Feel the Burn: For several turns, attacks that hit Excalipurr will raise his tension.
Battle strategies:
An important thing to note is that Excalipurr is weak against lightning attacks. If you have a character who uses an ax, use Parallax every turn to inflict extra damage.
When Excalipurr uses Feel the burn, only attack him twice a turn to avoid raising his tension to 50. Like most later bosses, Excalipurr already has a very high attack rating.
