Not sure if anyone tested Hachimonji, it seems to only consume 50
STP in exchange for a Multi Strike.
Tested on NIN/WHM with only STP gear and zero Multi hit:
TP/Hit =127 without any gear.[Zero STP]
TP/Hit =171 with 35 STP in gear.[No proc]
TP/Hit =127 with 50 STP in gear.[Procs DA, OAT, or Follow Up]making total TP return 254.
TP/Hit =190 with 50 STP in gear.[No proc]
TP/Hit =198 with 56 STP in gear.[No proc]
TP/Hit =205 with 62 STP in gear.[No proc]
TP/Hit =127 with 83 STP in gear.[Procs DA, OAT, or Follow Up]making total TP return 254.
DA, OAT Proc [or follow up attack] happens post 50 STP in gear, still working on the rate of consumption but from the samples I did its very high, almost 80% or something.[Need more samples, did around 1k Total hits]
Conclusion:
Unless....
Personally I haven't seen any upgrades with more STP added because I couldn't reach 100 STP in gear on NIN and no COR was around.
