Alright, this is an interesting ask. It borders on being something we wouldn't sell, but given the right limitations and a high enough price, I think we can work out a deal.

I wouldn't feel right pricing this out of anything but our top tier materials, so we won't bother with option 2. Options 1 and 3 will have the same cost, as those materials have the same base price.

The total price for this item would be 3150 GP, but with the following limitations:
-the blade takes 5 seconds to power up
-while activated, the weapon emits a soft sound (you can choose what this is)
-the weapon can only remain activated for 2 posts (1 minute) before needing a cooldown period of 3 posts (1.5 minutes).

What do you say? You'll be able to cut through some pretty tough stuff, but you'll have to time it well and use it strategically.
