Lost exp (in General)

I unlearned a low AS & received a little over 8000 exp in turn, then I picked CoC to replace it. But when I clicked the initial train to learn the spell it took all 8000+ exp & only trained CoC to 25. LOL what a ripe

Duh.

Fireball
Range 4
Targets 5
Training cost 8
Powerful ranged spell, but beware: unprotected friendly Minions will take half damage during melee rounds
Magic missile
Range 3
Targets 1
Training cost 8
Total damage is less than CoC, but MM concentrates all its damage on the lead opposing minion.
Cone of cold
Range 1
Targets 5
Training cost 8
The canonical direct damage spell. Damage is spread equally among its targets; if less than 5 targets are present, damage is correspondingly greater.
Decay
Range 1
Targets 1
Training cost 6226
Both the strongest and weakest direct damage spell in the game, Decay halves enemy HP and is unaffected by armor but will never kill an opponent unaided--Decay cast on an opponent with 1 HP will do 0 damage. (A Decay mage may still be the last Minion standing if BL or GA is involved, however.)

Clarification: PEBKC.

Oy, I have not heard of a PEBKAC error in a couple of years. Reminds me of when I use to see ID ten T errors all the time.
