Cone of Poisonous Gas:
Lasts a full round this 20-foot cone of poisonous gas can be used once every 1d4+1 rounds as a free action. It deals an initial 1d6 con followed by 3d4 con 1d4 rounds later. A DC 39 fort save will negate it. Can also cause blindness if the character is caught within the cloud of poison for the round. For the poision to effect the character, the character must breath it in.

Cone of Stone Gas:
This 60-foot cone of petrifying gas can be used once every 1d4 rounds, as a free action, however it can not be used any more than 10 times per day. This gas can cause the target/s to turn permently to stone. A DC 40 Fort save can prevent the gas from working for the round. This gas lasts for 1 round. This gas effects you regardless of whether or not your breath it in.

Cone of Fire Breath:
This 60-foot cone of fire breath deals massive damage at 22d10, the same as a wyrm Red Dragon. It can be used once every 1d6+1 rounds and requires a DC 38 reflex save for half damage. This breath is used as a standard action and therefore can be used after the other breath weapons, however if it is used, the other breath weapons lasting effects will be destroyed due to the extreme heat.

Cone of Chaotic Element Breath
This 60-foot cone of elemental breath shifts the type of damage every 1d4 rounds, if it is fire, re-roll. It can vary from Ice, Lightning, Sonic, Acid, and Force.

Rule of Breaths:
Since this beast has 3 different breath weapons I have come up with a special rule for them. The 2 that are free action, share a cool down and cannot be used while the other is on cool down. While the cone can be used after the others if the others are still stagnent in the air their airborne effects are destroyed.

Appearence: (imagine a DM's voice in the backround describing it)
A giant greenish blue monster looms before the party. It stands over 80 feet tall, this golem used to be the personal body guard to a powerful Arch Mage before the mage succummed to his natual life span. It took that Arch Mage over 5 years to create and gather the materials to build and animate this golem. With the body of an Iron Golem made of pure adamantine, it has the head of a dragon with the wings and tail to match it. The head also has a pair of horns adorning it. Embbeded into the right and left arms are two huge shields. The right is on the forearm and acts as a bracer while the left is closer to where the shoulder would be if the beast had shoulders. It holds in its left hand a huge great axe that glistens with powerful magic and in the right a blade appears to be melded onto the arm itself. Both weapons look to be extermely dangerous.

As you enter the room with it, a hollow voice bellows out echoing
"Who dares challenge the might of The Destroyer?"
(party's response)
"Then you shall pay with your lives!"

Alteritivly if there is silence, simply have the Omega Golem do the same and have the players roll their initives.
