Help with CR

Is there anyone on that could answer a question or two about writing a CR for me? Trying to edit Kupo to my tastes and help learn a bit about writing CRs at the same time.

Now the only part I edited is blow

Code:

                        //Need to check for insta procs first and foremost
						Spell.Cast("Thunder II", r => Core.Player.HasAura("Thundercloud") && Core.Player.ClassLevel >= 28),
                        Spell.Cast("Thunder III", r => Core.Player.HasAura("Thundercloud") && Core.Player.ClassLevel >= 46),
                        Spell.Cast("Fire III", r => Core.Player.HasAura("Firestarter")),
						
						//Thunder on targets at the start who don't have it
						Spell.Apply("Thunder II", r => Core.Player.ClassLevel >= 22 && !Core.Target.HasAura("Thunder")),
						
						Spell.Cast("Transpose", r => Core.Player.HasAura("Umbral Ice II") && Core.Player.CurrentManaPercent >= 90),
						Spell.Cast("Transpose", r => Core.Player.HasAura("Umbral Ice") && Core.Player.CurrentManaPercent >= 90),
						Spell.Cast("Transpose", r => Core.Player.HasAura("Astral Fire II") && Core.Player.CurrentManaPercent <= 20),
						Spell.Cast("Transpose", r => Core.Player.HasAura("Astral Fire") && Core.Player.CurrentManaPercent <= 20),
						Spell.Cast("Blizzard", r => Core.Player.HasAura("Umbral Ice II")),
						Spell.Cast("Blizzard", r => Core.Player.HasAura("Umbral Ice")),
						Spell.Cast("Fire")

The first mob it pulls it does fine to begin with. Attacks the mob with Thunder, then fire spams till it runs out of mana, but never transposes when it gets to low mana. And then from then on out, it just spams Blizzard, even when it's still at max mana, it never transposes back to fire. Any ideas?

 

I tried using Spell.Apply instead of cast, since it appeared that that didn't need a target.

I was working with LostCoder to test his version of Kupo and it did the same thing with his code. No matter what he did it didn't seem to detect the aura and cast transpose.

I'm posting this from my phone now, but tomorrow I'll post a log of it doing it.

 

You sir, are a scholar among men. Thank you. passing to the player worked perfectly.
