For th first question, I meant what is defined as "ability cost"? The Arch Mage's special ability says:
"Nullify the effect of a normal ability that has an ability cost"
What qualifies as ability cost when you are deciding what the Arch Mage can target?
According to page 13 and page 22: an ability cost includes fatigue, action forfeit, gold, AND once per round. So any ability which has a symbol next to it.
