0017c9b8 - 0017cac8
Parameters : r4 = Acting unit's data pointer
Returns : r2 = 0x00 If Ability is used (and updated)
-- All cases bellow abort action -- (Attacker 0x16e to 0x181 are cleared)
r2 = 0x08 if Unit is in deep water
r2 = 0x07 if unit can't act
r2 = 0x06 If Hamedo is triggered (no action)
r2 = 0x05 if unit is a frog attempting to do non frog things
r2 = 0x03 if unit does not have enough MP (And action menu = default)
r2 = 0x02 if unit is silenced and [Action menu = default or monster] and [Ability is silencable]
Store some ability data (See Notes)

Notes
Set 0x8018f5f0 to 0x00 (not reacting)
Set 0x8018f8c8 to 0x00 if Action is not taken (r2 <> 0x00)
to Acting unit raw ID (Unit 0x18a) if Action is taken (r2 = 0x00)
If Action is taken (ability used)
Store Acting unit used ability (0x170) at 0x80193d44
Clear Every unit 0x189 (Target's event ?)
Clear Every unit 0x19a (Reaction ID)
