Hecaton calculations

Hecatonchier

According to game mechanics, the chain bonus for RAV and SAB are scaled the same way in eidolon fights, so just calculating the chain bonus increase for each string.

Chain Resist: 90%

These both assume all debuffs are inflicted (Deprotect/Deshell/Imperil)

SAB

Deprotect:
[(4.0)*0.1 + (0.5)]*1 = 0.9
(re-inflict +0.5)
(Conditional: SAB/First stock/3 debuffs)

Deshell:
[(4.0)*0.1 + (0.2)]*1 = 0.6
(re-inflict +0.5)
(Conditional: All/Different)

Imperil:
[(4.0)*0.1 + (0.2)]*1 = 0.6
(re-inflict +0.5)
(Conditional: All/Different)

Total: 0.9+0.6+0.6 = 2.1 (+1.5 = 3.6 max)

RAV (spell choice is arbitrary as long as alternates and not aero)

Fire:
[(10.0+1.5)*0.1+(0.1)] = 1.25
(Conditional: Weakness)

Thunder:
[(10.0+1.5)*0.1+(0.2+0.7+0.1+0.5)] = 2.65
(Conditional: Difference+Weakness+RAV/3 debuffs)

Fire:
[(10.0+1.5)*0.1+(0.2+0.7+0.1+0.5)] = 2.65
(Conditional: Difference+Weakness+RAV/3 debuffs)

Total: 1.25+2.65+2.65 = 6.45
