The real power of these is in the added affect and not so much from the base damage. It is worth it to buy a stack (12) of these just to throw around for fun, even if only once.
Oh yeah, desynthing one of these would be fun, wouldn't it. Using a highly powerful electric charge on something to rip it into it's basic pieces... on an explosive device?
Use lightning crystal. Throw in grenade...
BOOOM.
(heh, just funny. I'm almost scared to try though.)
I am the proud buyer of the only stack I have ever seen for sale on Fairy. I bought the stack w/ my mule Domime in San'Doria for 4K. I was really just bidding to see where the person set the price ^^.
Now- the big question in my mind is whether the the seller crafted them- or was reselling from an NPC after deciding he/she didn't want them...
