I did manage to get the 2nd leve's reward in the 3rd try, and 3rd leve's in the 1st (I consider myself very lucky there)
Also, Magnesium: You mention "Jellies" in your strat for the 2nd one, and that made me think i'd meet Flan-type enemies, not Jellyfish-type enemies. I did understand it was jellyfishes as soon as I made it through but it is weirdly confusing (it shouldn't be, not sure why it confused me)
As a further note for that leve, as long as you have Hallowed Ground: As soon as you get past the two ghosts, get as close as possible to the jellyfishes, give it a moment to see if you did not grabbed ghost aggro (it's very important, they'll leash back before they hit you but you cannot have aggro on them).
If you don't have aggro, pop Hallowed Ground, immediately get on your bird and run, it'll give you just sufficient time to get all the way up to the target up there, you'll have a huge amount of stuff trailing behind you so don't get stuck on terrain.
