pathfinder synthesist weight.

[Ryulin18]

Would you rule it that a synthesist summoners eidolon, an image surrounding him, has a weight? I thought it was a weightless being?

Asking because my friend is trying to climb down a rope and the dm said the rope snapped.

It provides you with ability scores, armor, extra HP, natural attacks, wing-powered flight, stability, and much more. Unless otherwise stated, I would say it has Mass, and therefore weight. I've seen it as a transformation or a sort of exoskeleton, not an "Image"
