"No one deserves this. Its this place Elsa, everything is warped, dead things live." MIra replies, looking with her eyes for a large branch, something to use as a club. "I wish I would have gone up there now."

Lowering Pyros down again, Jerry seraches for secret or concealed doors, including looking for seams, buttons, joins or rotational marks.
If that shows up nothing, she'll use the vantage point to look for possible remote entrances, perhaps a cave in the canyon wall..

Not sure if Observation helps.

Whispering, "Do you have anything like a saw or something to cut this damned thing open?"

[observation does help, Jerry still does not find anything]
[a hole in the clay statue could probably be made with a blunt melee weapon. it would be noisy, though]

Mira searches, but everything nearby is made of crumbly red adobe. Elsa notes Mira casting about for something. What are you looking for, maybe I can help?
[elsa has a spare club or would loan mira one of her 2 maces if the bard mentions it]

(Would Pyros think that maybe its possible to break through further down, rather than breaking through up here? Or is it only the statue?)

[at this point it seems only the statue is hollow. the ziggurat may indeed have an interior, but if so the walls are thick enough that it doesn't seem hollow from outside, but there is no way to know for sure without trying]

"Swords and crossbow bolts arent going to do much against a skeleton. I was looking for something to bash them with." Mira explains as she gives up, "I'm feeling a little useless down here, I hate that."

Jerry whispers, "Don't you?"

======
Would scraping the bird to check it's hardness count as an attack? Or pushing the thing?

Wanting to br quiet, Pyros will first prod the statue with his dagger.

[scraping or digging at a stationary object wouldn't count as an attack for the purposes of the spell. bashing it with a mace would]

Pyros prods at the statue with his dagger, and finds it much like poking a ceramic bowl or brick wall. Scraping would probably result in a sharp screeching sound.

Elsa unhooks her mace and hands it to Mira. Try this. I'm better with my sling anyway, and i have the silver mace if i need it.

The bard takes the heavy weapon gingerly, turning it gently trying to find a suitable place to rest the weapon while adjusting to the heavy weight. "Damn Elsa, no wonder you are so damn strong. This thing is ... It's bloody heavy!"

Jerry tries to assess whether the rope, if looped with the grappling hook around the statue, would reach to the party on the ground.

If so, she tries to do so (or get the much nimbler Pyros to do so, communicated via whispers) with the objective of the bird being toppled (or preferably 'walked' aside) by the party below tugging on the ropes but still preserving the duo's Invisibility spells.

Pyros stops mid swing at the statue when Jerry starts to whisper. "Do you have any rope also?"

She whispers back apologetically, "Sorry, no."

[Pyros' rope is about 50 feet long. wrapping the wide base of the statue would use about 22 ft of it. even if pulled fully taut, it would take another 56+ feet just to reach the ground, and that doesn't include room for people to pull. with 100 feet of rope you could attempt it though. However, the massive size of the statue and the way it is secured in the ruts on the base make it seem very unlikely that the party would be able to topple or slide it in this manner]
