Mobile Benefits of an artificial crimson biome

[M_Lucario_EX]

Hey guys, I made an artificial crimson biome in my world on Terraria mobile, and my world originally had corruption. Even if I keep the crimson from spreading, is there any real benefits of having an artificial crimson biome in a world that originally had corruption? I really don't feel like taking it down.

It's not necessary to keep a crimson biome around but the crimson exclusives can sometimes be useful. Notably, the Vampire Knives, Heartreach and Rage potions and Ichor.
If you're not into fishing and/or potion brewing, there's not much the crimson can offer in the late-game — you can farm the Vampire Knives in another world if you don't already have it.
