Why people still use arka4 :\, tef wand and shield combo is better. Cure casting speed is very important, specially on voidwatch. i also notice most of the sets posted on this thread have no casting speed at all
I use Arka IV when idling in Terra's Staff, and Tefnut when idling in Owleyes, so I don't run into issues of gear swap clashes when trying to equip the shield or grip.
My precast sets for staff and club (still lots of room for improvement):
56% in gear (62% with Genbu's Shield) and 20% in merits puts me at 76%-82% before accounting for subjob. /sch should put me at ~78% when using a staff. I have no intention of getting a -cast time magian staff since that would remove a huge chunk of cure potency when quick cast procs (or if spellcast lags).
Ideal precast set (I think):
Genbu's: 5% potency/8% cast time augment
Swith +1: 4% fast cast
Total fast cast: 79% cast time before subjob. Could get another 1% easily enough, but kind of pointless since subjob should push it to 80% regardless, and even if it's possible to go higher than 80%, it's impractical to take advantage of it given that 80% cast time reduction means 0.5 seconds between start and end of cast. Putting potency/skill everywhere else in case of quick cast.
Totals:
Fast cast: 79%
Potency: 50%
Skill: +58
Mnd: +57
Vit: +3
Numbers for hume whm/sch with capped healing magic skill, in case of quick cast:
Code
Cure 1 Cure 2 Cure 3 Cure 4 Cure 5 Cure 6
Skill 482
Mnd 148
Vit 86
Power: 577 63 138 315 590 743 936
Potency: 50% 94 207 472 885 1114 1404
Cureskin 25% 23 51 118 221 278 300
Total: 117 258 590 1106 1392 1704
Doesn't look like it's possible to improve on that with staff. Staff adds 4% cure potency, but the only other items with cure potency that might potentially get swapped (orison head, heka body, roundel earring) leave you at a net power potency deficit.
Totals:
Fast cast: 81%
Potency: 50%
Skill: +49
Mnd: +47
Vit: -1
So you lose 9 skill, 10 mnd and 4 vit for 2% quick cast and 1%-2% fast cast. (suppose you could drop Loq to put it at the same fast cast as club, and replace with 3-4 mnd from earring to close the power gap a smidge, but doesn't seem worthwhile)
edit:
why my sets no show up? Thanks Aleste
edit2: goofed on the numbers; fixed.
