This what i would consider the optimal multi hit spell set up for the big 3.
- FFXIAH.com
Acc +35/40 (latent on perdu) dex+31 str+41
Its a nice solid mix of acc/str/dex/skill which with sushi should have you fine for any merit level mob. (anything you wouldnt land multi hits on like gods you should be /thf anyways and using single hit spells). You'll notice i favor using PCC and optical hat over other pieces like morrigan's/chain/etc. Reason is on a per slot bases you get the least str/dex returns to acc returns compared to other slots. The only really 2 hard pieces to get out of this set would be Koggelmander (MMM drop), and Cuchulain's Mantle (Campaign ops drop). You could buy the mantle if you camped long enough though and with a steady group should be able to get the sword eventually. Though if you cant get the mantle smiloden+1 and potent's belt works as a nice filler combo (2 str gain lost 9 dex and net gain gain of 3.5 acc)
Anyways as a general rule frenetic rip and disservement are stronger/more reliable then hysteric barrage simply due to less hit (3 FR) or a acc boost under CA (disservement).
A 5 hitter with no acc boost naturally takes more work to consitant returns. Though even with capped acc (95%) youll still only connect all 5 hits 77% the time. Just like ws you should stack acc to land hits reliable then work on str/dex. (however to hit 4/5 hits with capped acc is 81% the time so essentially a 4 or 5 hit is almost the same chance meaning capped acc is the #1 way to get consitant reliable dmg) As a nice bonus disservement and i think FR have dex as mods which is another way to get a dmg boost (double dipping into mod+acc boost from dex)
(btw with the worst dex rating you can get for this (elvan 60) you get a net acc of 470 with this set up almost capping you on thf mammol ja)
As after though ideally you would use ancient torque for 4 more dex and 1 more total acc gain but i didn't think about it as its outside most players attainability.
