Belashyrra

Belashyrra: "Welcome, pawns! I was just about get started, now that I have created a suitably impressive avatar for this world. Do you like it?"

Orlassk: "Belashyrra! You can't escape your stone prison in Khyber that easily. The power of stone is mine, after all. Feel the presence of Khyber in my creations!"

Belashyrra: "I SEE .. THIS IS YOUR MOVE THEN, IS IT?"

Orlassk: "YES. MY PAWNS AND STONE TO YOUR AVATAR. CHECKMATE IN TWENTY THREE..."

Belashyrra: "HAHA! LET US SEE HOW THIS ROUND GOES FIRST! LET'S BEGIN!"

Description: As the fight progresses, Belashyrra will summon various minions to aid him, including Evil Eyes, Greater Evil Eyes, and Armored Beholders. Note the room where the end fight takes place has a dimensional anchor, so Teleport and Dimension Door will not work there.

Orlassk's gargoyles help reducing Belashyrra's power while they are alive. If they die, his powers start to grow, allowing him to summon more powerful Beholders, getting stronger DR, and dealing more damage with his attacks.
