Number? Eh... not really sure. 2 per try, 20% chance/ 20% completion, so... bleh... uh... 50-ish I think?
1/5 x 1/5 = 1/25 x (2 per attempt) = 50. Hopefully that'll be enough to do it fully... Once I get the barbarian enchant I'm commissioned for I'll set to work rafting for the iron to make it.
As for urgency, it's your shield, so your pace. If you want it quick, gather quick, if it's not a big concern, feel free to take your time. It'll probably take me a few days to get the ES anyway.
Go away, Fracture.
