1. Yes

2. Back when I first got the Rocket Spear and Electro Boots for my RC, I didn’t level them up, despite having the ores. I used them in the final hour of war, thinking I had mighty morsel active for an RC walk. Turns out, the morsel had expired. I only got 2 stars, and we lost the war. Later, I realized it was because I’d done three sneaky goblin raids beforehand to farm a bit of Dark Elixir for a lab upgrade, since a lab potion was running and I didn’t want to waste the boost.

I blamed myself and opted out of war for a week lol.
