Replica Duskdawn - 10% base crit 1.25 APS, interesting for CoC? Let's theorycraft!

Hi,

I was checking all the replica items to see if I could find a fun new item to build around and I saw the new replica Duskdawn. It's identical to the original, but instead of criticial chance for spells it has base crit chance, bringing it to a respectable ~10%, with 1.25 APS.

I was building around it on PoB, using a trickster and stacking block, and ended up with something interesting without using insane gear or cluster jewels:

• 4.4k Life, but...
• 59/17 attack/spell block
• Phase Acrobatics
• The new Arctic Armour that freezes everyone that hits you, for 0% mana reserved (chest piece)
• Ghost Shrouds
• Respectable Shaper damage (~8 aps, 200k arc average hit), nothing too fancy but can probably be improved upon.

I was wondering if anyone else tried something with this weapon, because it looks kind of OP!

Id love to hear your opinions on this, any theorycrafting is welcome! Very basic PoB is here: https://pastebin.com/AK2hYm4Q

Cheers!
