What are trigger spells?: Trigger spells are spells you used to trigger an action other than the spell itself. For example, you might use Fire V to equip PDT. Since hitting Fire V equips PDT rather than casting Fire V, we would consider that a trigger spell.
Why use a trigger spell rather than /sc equip SetNameHere?: Trigger spells, unlike manual equip (/sc equip), prevent all other actions from occurring unless the action was a predetermined command action. Think of the following example to clarify that point:
- I hit my macro that makes me cast an ancient magic
- Under normal circumstances, this would mean Precast (Fast Cast) > Midcast (Nuke gear) > Aftercast (Idle)
- During the cast, I need to equip PDT for a TP move the mob starts up
- Scenario 1: I use a trigger spell to equip PDT => Precast > Midcast > PDT > PDT until I determine the PDT is no longer necessary
- Scenario 2: I use manual equip for PDT => Precast > Midcast > PDT > Idle
- In the first scenario, I keep PDT on until I'm ready to unequip the PDT; in the second scenario, Idle will automatically equip at the point when you would have ended the spell
- Scenario 2, therefore, may not be desired because if the TP move has not initiated or you wish to maintain PDT gear for a subsequent TP move (Multiple TP moves in a row), you would be unable to do so
How do I macro trigger spells?: For sets you want to use on-the-spot, you macro them the same way you would normal spells. If, for example, your idle spell is Thunder V, you would simply type " /magic Thunder V" within your macro. Upon hitting that macro, you will equip your Idle set.
There are too many trigger spells to macro: Remember, you only need to macro trigger spells relating to stuff you wish to use immediately. Thus, you would typically macro Idle/PDT/MDT/FullEvasion sets. For other trigger spells that allow you to rotate options (EX: Change between using a higher tier of resist gear or change the maximum distance before cancelling WS), you want to bind them (See "Binding Trigger Spells").
Where do I find a list of trigger for my particular spellcast?: Typically, the author will write out the trigger spells and their function within the rules section of the spellcast (Do a search for "Rules"). If not, they may opt to write out the trigger spells on a separate post or file that is easily located.
