Starting to play the Quartermaster, these questions came up:

1. Can I use Scroll of Recall to refresh a Stamina Potion, and the immediately use the refreshed Stamina Potion to get back Scroll of Recall and another card?
2. Can Reforge retrieve itself?
3. Can I play Sharpening Kit for its active bottom, use its effect on my turn to boost my attack, and then at the end of my turn send it to the discard pile and retrieve it with a Stamina Potion?
4. What kinds of items can I use to trigger Proficiency? Could I use, for example Pendant of the Plague or Moon Earring or Stamina Potion, even if those items don't affect my attack directly?
5. If I use a Power Potion to buff Catastrophic Bomb and turn up the "Refresh" modifier, can I immediately refresh my Power Potion and use it again to apply to this same Catastrophic bomb, effectively using it twice on the same attack?
6. Can I use a Moon Earring or Pendant of the Plague or Stamina Potion between two Catastrophic Bomb attacks, if I'm trying to get multiple item refresh modifiers?
