So, Abyssea has been around for a while now. Many players have much experience hunting Abyssea NMs and triggering the colored !! weaknesses.
And yet, I hear myth statements quite often still.
Here's some of the gems I've heard of late:
Cure spells are yellow !! trigger spells of the NM is undead.
Treasure Hunter doesn't matter in Abyssea. Only !! weakness triggers affect drops.
If the NM's name "turns yellow" due to its target disengaging (NM is still aggressive towards the party), then all the !! "procs" are lost.
If you use a trigger WS and it creates a Skillchain, it won't trigger the !!.
Elemental DoT spells (Burn, Frost, etc.) are yellow !! spells.
Ichi-level ninja spells work the same as Ni-level ninja spells for yellow !! triggering.
Tier I and II elemental magic nukes are yellow !! trigger spells.
Unless anyone has some hard evidence that I've overlooked, none of the above statements is factual ... they're all myths.
Remember when players used to think Divine Seal on a Raise shortened the Weakened Status timer? Or when the THF needed to killshot the mob to get the best Treasure Hunter effect?
