Latest revision as of 21:21, 14 March 2022

Counter, Counter Tackle, Counter Magic, Counter Flood, Brave Up, Dragon Spirit,  Sunken State, and Caution Usability:

Parameters : r4 = Target Reaction Ability ID (determined from Target reaction set)
             r5 = Ability flag to check (0x80 = Counterflood flag - 0x40 = counter Magic flag / 0x10 = Counter Grasp flag)

If Used skillset ( 0x801938d4 ) is Math skill : skip the routine (no reaction)
Checks if Used Ability has desired flag enable (using 0x801938f6) if not, skip the routine (no reaction)
Test Unit Brave% as chance to react : skip the routine if failed

If Targeted Unit react :
- Store Reaction Ability ID in Target Data 0x19e (= current action 0x0e)
- Store Used Ability ID (from 0x801938d6) in Target data 0x1b2 (current action 0x26) - last attack received ?
