Nyght's tale competition 1

My first entry to toboisgreat's [link] Design a Boss for Nyght's tale contest.

Meet Klaus the Mountain Troll

Name: Klaus
Brief Description: Klaus is an ancient mountain troll known for his grumpy temper and colossal tantrums. He likes nothing better than to be left alone and hates nothing more than intruders in his mountain home. It is unfortunate that Nyght has to cross his backyard (the mountain range) on his way...
Size: Big
Elements: Earth
Main Colors: Grey/Brown/Yellow
Main attack: Stomp (Jumps and stomps the ground sending a shockwave travelling along its surface)
Secondary attack: Stone Rain (Strikes the ground sending around a shower of shrapnel)
Weapon: -

Misc: Fighting Klaus is both a question of endurance and agility; He's slow, really slow, but all his attacks are area attacks, he knows how to take a hit and he has a buttload of hitpoints.
