OOC:
Yeah, that might be tricky. I was hoping I'd be able to consider it a trap, and therefore disable it using thieves' tools (normally a Dexterity check, though his Intelligence is the same bonus).
As far as the bugs, I was hoping to do it from outside the room, using Mage Hand. Using your Mage Hand to disarm traps at range is one of the abilities expressly granted by the Arcane Trickster feature Mage Hand Legerdemain.
Even if all that's allowed, it would still only be a +7 to the check, which makes a DC 20 a big risk. Nirion could Help ("Wait! Don't cut that string yet!" etc) for Advantage, which makes success more likely, but an unlucky roll could see them both sucked into the Astral Plane and blow a big hole in the ship.
In comparison, throwing it overboard is completely safe. So do we roll the dice and gamble, or just abandon the items safely? Personally I want to risk it, but I think it's a decision that everyone should be involved in since it has potentially catastrophic consequences.
