<SC_ReleasedDamage: (State ID)>
Assigns a (State ID) when released by damage.
<SC_ReleasedEndBattle: (State ID)>
Assigns a (State ID) when released at the end of battle.
<SC_AutoReleaseTiming: (State ID)>
Assigns a (State ID) when automatically released due to the passage of turns,
etc.

#Example:
<SC_ReleasedItem:3>
<SC_ReleasedSteps:\v[1]>

<SC_UnlockTriggerSwitch:(Switch ID)>
Turns the switch ON when the state is unlocked.
Example:
<SC_UnlockTriggerSwitch:10>
