How do I make this into a BBEG?

Here's your "ugh".

Make it a lich's phylactery
It becomes a golem when threatened

Put googly eyes on top of it.

Also, Ugh.

>BBEG

No, thank you.

Make it permanently on fire (yet doesn't burn itself) and shoot lightning in random direction every d6 rounds.

>No, thank you

Ugh.

>Gazebo golem
Some jackass player says "I attack the gazebo"
it animates and kills the entire party

>Immunity to arrows
>Immunity to melee weapons
>Immunity to parlay or any kind of charm/enchantment
>Immobile, unmovable.
>Infinite HP

It's already a BBEG, user. A very tough one.

It's haunted by a charming and knowledgeable spirit. Placed in the palace park, it advises leaders and kings, and ultimately the players, with great wisdom. Many great men rise to fame started with a calm talk with the gentle spirit. But while doing it, it actually manipulates everyone to destruction, so that everyone will follow him into the tomb.
