1. A general problem I'm having is without any perks that augment damage, my newly created spells inflict less damage on creatures than what's listed in the magnitude with auto-calculate off. I check the health values in-game with the console. Same issue with spell cost, although I understand there is a skill multiplier that decreases spell costs at higher skill. What can be causing this disparity?

2. Is it possible to remove or negate the skill multiplier when it comes to reducing spell costs?

3. I've been at this particular task for hours and I'm unable to get what I want, at least inside the Creation Kit. I haven't attempted any scripting on this yet.

My intent is to create a new Firebolt spell that when the Dragonborn is able to dual cast and has another perk, Firebolt will use the Incinerate projectile. What I've done is make 2 magic effects, one as regular Firebolt and the second as Firebolt with dual casting art set for FireboltExpertProjectile01, and set both effects to a single spell. Each magic effect has target conditions like the following (not on the Effect Item window of the spell, on the actual effect):

Firebolt (this one is setup like this so it would be usable for dual casting but you would see no Incinerate projectile)

1) Run On: Target, Has Perk: Incinerate40 (my perk) == 0 AND

Firebolt Incinerate (the one with the Incinerate projectile dual casting art)

1) Run On: Target, EffectWasDualCast == 0 AND

2) Run On: Target, HasPerk: Incinerate40 == 0 AND

The problem I can't get around is that as soon as the Dragonborn is able to dual cast, the dual casting art is used. The HasPerk condition doesn't seem to effect when this is used. The idea is that when able to dual cast and has the Incinerate perk, then you would see the Incinerate projectile on dual casting. I've been fiddling with the target conditions for many hours now and I can't seem to make it behave. I also tried setting the second magic effect to use the Incinerate projectile when it was cast, dual or no, and it produces only the regular Firebolt projectile. I've also tried Run On: Player, Subject... No luck at all.
