Which Sacrifice?

[Daemon]

People use Apamajas for stun because it is a Thunder spell, yes, but it is classed under dark magic. Blind and Dispel are classed under Enfeebling, not Dark, thus Dark magic skill has 0 effect on them, however they are dark element. Really if you wanted you could call 'Dark' magic Arcane magic, since its what they use as a name in other games. If you go by that, its a little easier to understand. Stun is an Arcane spell, Blind and Dispel are Enfeebling spells, while Blind and Dispel are dark based spells, they are not effected by Arcane skill, and Stun is wind based, which is why a wind staff works for it.

Eh I'm not understanding you on this. Spells are classified by Element and Magic Skill. No where did I see stun classified as Wind element. Although Gravity is wind element.

Gravity
Spell cost: 24
Spell element: Wind
Magic skill: Enfeebling Magic

Even White mage spells follow the same.

Addle
Spell cost: 36 MP
Spell element: Fire
Magic skill: Enfeebling Magic

I've played in WoE many times to say that when certain spells did not land, combining gear to increase magic skill and element have shown to work vs only following the magic skill of the spell, with of course INT or MND and Magic Accuracy.

Even equipping Zammzummin staff with Kaikias Cape has made my Gravity land to a very noticeable difference in Delve.

No where did I see stun classified as Wind element.

Sorry, that was a mistake, I meant Thunder.

Spells are classified by Element and Magic Skill.

This is what I was trying to explain. There is a Dark element, and a Dark skill, they are not in any way related to one another. If you renamed the Dark skill, Arcane Magic, it makes things easier to understand. Stun is a Dark(Arcane) Magic, but is of the Thunder element. Blind and Dispel are Enfeebling Magic, but are Dark element. Dark Magic skill has no relation to Dark element magic, the only thing it correlates to are the spells in its category, in this case, stun, while as you see, some spells in said category can have different elements than dark as well. Think of it like Divine, though it is a much weaker example, Divine is the same as White Magic Skill, like Dark Magic Skill is the same as Arcane. Just because a spell if Light based, does not mean Divine enhances it, likewise, just because a spell is dark based, it does not mean Dark skill enhances it. Because they are simply categories for spells, not effecting a certain element in any way.

You are pointing out their elements, but their elements have nothing to do with it. If you read Dark Magic Skill as Arcane Magic Skill, everything would look as it should, and as it is, and becomes easier to understand.
