Test basis:
1. Team consists of: Hercules/Nike/Oceanus/Ganges/Kushinada, Sub: Undinde/Rusalka
2. Nike and Oceanus had accessories equipped in first few battles (leftover from tower event, no DA/TA), which were later removed.
3. Weapons equipped: 7x Frost Bow Nahalzanab (Assault(M), Rush(S)), 1x Cannon Ilul Lore (Defender (M), Rush(S))
4. All bows were LB 0 lvl 1 slvl 1, gun was MLB, lvl 125, slvl 1.
5. Eidolons equipped: Meng Huo (main eidolon), Illuyanka, Yam.
6. All eidolons were max lvl.
7. Support eidolons chosen by preference in order: Meng Huo > Diabolos > Jormungandr > Jack Frost > Vlad.
8. All battles were done againts "Cave of Conflagration" Expert level.
9. Maiden's Prayer taken as ex skill.
10. Only heal and cleanse skills were used (aside from one Herc's defensive buff misclick).
11. It is assumed that poison, scorch and blind debuffs have no impact on DATA.
12. It is assumed that RNG is decent (tbh I am starting to think it's not).
13. No Kamihime died in course of test.
14. All battles used for test were recorded, data was taken from recordings.
Results ([Total number of attacks]/SA/DA/TA):
Hercules: [953]/832/84/37
Nike: [906]/800/82/24
Oceanus: [876]/785/72/19
Ganges: [843]/747/72/24
Kushinada: [811]/726/70/15
Total: [4389]/3890/380/119
Probabilistic results (SA/DA/TA):
Hercules: 87.30/8.81/3.88
Nike: 88.30/9.05/2.65
Oceanus: 89.61/8.22/2.17
Ganges: 88.61/8.54/2.85
Kushinada: 89.52/8.63/1.85
Total: 88.63/8.66/2.71
Conclusions:
Pretty much none. Few things one can derive from results (they are not certain though):
1. Rush(S) base percentage is 0%.
2. Rush(S) increase per slvl is probably either 0.05% or 0.1%.
3. Base chance for DA we know (8%) is probably right.
4. Base chance for TA we know (3%) couldn't be confirmed.
