I do have Seraph Tracers, but only 3 heart statues
Do you mean something like making a stretch of hallowed grass all across the world?
Because I think that would work.
I also have the Otherworldly Rune from the Thorium Mod, which means infinite flight time.
Or just use a Clentaminator with Cyan Solution (purchased to the Steampunker in a Hallowed Biome).
3 heart statues can work. Of course, the more you have the easier it is.
