terraria
I want, for aesthetic and security reasons, to keep the Hallowed biome out of my village. Problem is, before I managed to stop it, it had already spread quite a bit, so I'm searching for a way to quickly remove it.
I don't want to have to go trough each patch of grass and to remove the hallowed grass, and the purification powder don't work on it. Is there another way?
Baseline answer: A mob (evil NPC) must be standing on the same level as the door to open the door.
Mobs can jump but will generally only do a large jump if the player is near by. So while it may be possible for them to do so, it is not entirely likely. The thing I would be concerned about is when the monsters spawn on the ledges because you just happen to be standing at the right spot to make it a valid spawn location. Putting in good NPCs will help with this a bit, but its still a concern.
Here is a picture of my last base (well, two towers out of it, it expands more to the left with a couple more buildings). All the doors seen in the picture are mob safe, they are up one block from the standing level the mob will be on, and there is nothing for the mob to jump to as long as the door is closed. There is one weak spot on the right hand tower, if you look at the internal doors on the right side of it, they are on the level with the flooring.. So if a mob can get through the lower right hand door (which is offset properly mind you) then they can jump to to any level and start running havoc!
Hope this helps!
I'm going to be cataloguing my findings here, don't hesitate to post your own answers.
Letting the ocean become hallowed/corrupted will make corrupt/hallow desert enemies spawn instead of ocean enemies, making the following items unobtainable: Shark Fin, Diving Helmet, Coral; their products will also be unobtainable: Megashark, Neptune's shell, waterwalking potion, hunter potion, diving gear, gills potion.

Sprinkling vile powder or throwing unholy water will remove hallow. You can make vile powder from vile mushrooms at an alchemy station or purchase it from the dryad during a blood moon. Unholy water is crafted from a bottled water, an ebonsand block, and corrupt seeds. Note that unholy water will not just remove the hallow but replace it with corruption.
