1) I got Destruction spell and had quest to "Kill one Dragon". Can I complete the quest by using spell to dragon and discard it or do I have to kill it in battle?

2) Quest says "Lose one life" Can I just discard one life immediately at the start of the game or do I have to lose it as the game goes along (E.g. at battle, through some event/encounter etc.)

3) Quest says "Discard 3 Gold" Can I immediately discard 1 gold and only have to discard 2 more. Or do I have to wait to get 3 gold and discard them all at the same time?

4) Same question as above but replace gold with Followers

5) Same question as above but replace Followers as Objects/Magic Objects

#1: No, Destruction doesn't help, have to do a combat, though could use a spell like Fireball in that.

#2: Yes, you can just discard one life.

#3: Have to wait until you have 3 gold at once.

#4-5: Same.
