Demon Altar question

[0carus]

I read that breaking these altars with the pwnhammer causes a random block in the world to be corrupted. My question is do the first 3 demon altars broken do not corrupt a random block? Will it only start corrupting after the 3rd broken altar?

Each time you break one, it has a 66% random chance to spawn a Hallow or Crimson/Corruption block in the world. It doesn't matter if it's your first altar, first 3 altars, or your 100th that you've broken, it's always that same chance. So you could get lucky and not have them spawn any corrupted blocks.

Sucks then. Thanks for the info. I'll probably just destroy 3 cause I hate corruption. Made 5 hellevators just to contain pre-hardmode corrupted biomes which took me 5-10 hrs. Gotta worry about the V after wof and now these random corrupted blocks, great! I still love the game tho!

you could also just not break any of them if you are worried.
the three/six hardmode metals can be gotten from crates as well, without having to worry about creating any impurity in the world. you can even fish up crates prehardmode and them open them in hardmode to still get the metals.

Pre-hard mode the Corruption/Crimson Don't Spread, and once you defeat the wall of flesh a diagonal line of Corruption/Crimson & Hallow Spawn intersecting at/near the spawn of the world. After you kill a MecBoss you can for a 2 platinum buy a Clentaminator from the Steam Punk. if you didn't already know, So just to let you know you kinda wasted hours Containing the Pre-Hard mode Evil Biomes. The ore alters you Break the more Ore you get making your time Mining altogether less
