These are all easier once you have healed all of the corrupted lands.
Why? No enemies, by this time you will also know the route, no annoying pieces of corrupted slime on walls that will make wallrunning harder, you will also have shortcuts thanks to Elika's unlocked abilities.
There’s no need to freak out on these achievements since they are all easy, just make sure you use Elika’s compass ability () to pick the shortest route. Warp to the starting point, place a marker on the end and go for it.
