I want to make a spell that will cause my enemies to be 100% weak to Fire and do Fire Damage at the same time, but with the weakness accounted for. In which order would I add the spell effects in the Spellmaking menu to create such a spell? Thanks!
You can't do both at exactly the same time, since the game is coded to not apply weaknesses to any damage done in the same cast of a spell or strike of a weapon. It only applies on subsequent hits.
And in order for it to work right, you
have to list the weakness effect after the damage effect.
Spell effects go off in the order in which they're listed, and if a new cast of a spell goes off while the duration on a previous one is still running, the new one simply replaces the previous one.
So-- on the first cast, you do the base damage and start the clock on a weakness effect (make it at least a second or two longer than the duration on the damage effect-- I like 1 second of damage and 3 seconds of weakness).
On the second cast (if it's within 3 seconds, or whatever duration you've set), the damage goes off first and is modified by the weakness that's still running from the previous cast. Then the new weakness effect goes off, resetting the clock on weakness to fire.
And so on.
If you list the weakness effect first, then every time you cast it, the first thing that happens is the clock is restarted for the weakness effect, then it doesn't do anything to the damage, since it's in the same cast of the spell.
