Ok so my idea would be setting DW4
solo content as /dnc
thaumas body shetal dw earrings
These would let u be capped on att speed considering in solo content erratic+samba
(1-dual wield)(1024-gear haste-magic haste-ja haste)
(1-0,43)x(1024-256-307-50)= ~%22.8 so ~%77.2 reduction
If you had 50 total DW, it would be;
1-[(1-0,50)x(1024-256-307-50)] = %80 reduction
So you need 7 more DW on top of shetal and DW earring set.
edit: I was told that haste2 is 307/1024, not 300 and double checked on bgwiki, so fixed the math.
suppa, shetal, haverton ring and the new Su1 dw+4 legs would take it from 30 to 50 but then 10 stp from rajas+iuitl legs would be lost >.<
