Ryx thinks for moment… “he might’ve stolen it from another guard as well. Maybe we should check if anyone is missing one.”

Aruzhal slowly nods his head in agreement. “Mayhaps. I art ready to return and ask Ronaldo about the weapons, if thou art as well.”

Yes, I think we have learnt all we can here. Let’s go back to Ronaldo. 

Bokshir, from the top, it appears to be roughly a 40 foot drop onto the tallest gold pile visible. Also, if you agree, then the party will call the King to bring them down, and head back through the door to the main room of the Golders Guild to meet with Ronaldo

"If give time, can see magic here", Bokshir suggests. "Ten minutes only".

If the others agree he will ritually cast detect magic and focus on the area around the footprints, and the guards in case something was cast on them. If the others decline, he is ready to go and see Ronaldo.

While waiting, Ryx just goes around and casts prestidigitation to clean himself, his allies, and the guards.

Aruzhal crosses his arms and waits, rigid and frozen in place.

The Magic that Bokshir Detects is from the Hoard, there is SO much magical energy coming from the hoard that its hard to detect anything else.

Bokshir tries his best to focus away from the hoard and onto the guards present, wondering if the hooded guard has maybe cast some kind of spell on them. Even if that means asking one of the ones that saw the hooded guard to move away from the skylight for a moment.

roll a wisdom saving throw

Bokshir Wis Save: 3+5=8

the harder you focus, the more it starts to hurt, take 1d4 psychic damage, and the spell ends

Bokshir whimpers in pain, and sighs.

"Hoard magic too strong", he says holding his head. "Best go".

Psychic Damage: 3

This is the point where the party goes down to see Ronaldo, where he looks up at you "Can I... help you?"

Yes, we learned there was an unknown guard wearing a hood and wielding a standard guard spear. Do you know of anyone let up there besides the regular rotation? Also, do you know if all weapons are accounted for?

"Umm... All weapons are accounted for... what post was this supposed guard at?"

“The skylight of his majesty’s hoard.” Aruzhal answers.

Well, Last Night, and right now, I have 4 guards sectioned to the Skylight. Based on what you're asking, Was there apparently a 5th guard there last night? Or now?

There were only 4 now, but they said another joined them earlier and didn’t say much. 

Hmm, did they say weather this guard had a spear? because all weapons should be accounted for. If this mystery guard had a spear, I'll have to question my guards to see who wasn't at their proper post... not to mention who apparently has a hood.
