[Buying] Steel spikes at 20k!!!

For the moment I am paying a ridiculous 20k per spike.

Also buying charged steel spikes at no price difference.

You get them from enraged silverfish. Enraged spawns must be on in player settings (/ps). They spawn from any kind of natural spawned ore in the over-world at any y below sea level. Use fire potions and melee to avoid low risk detection.

I am also convinced you need to be using a non-silk pick. I see no need to test this because I wont risk wasted effort.
Not sure it must be below sea level but I can confirm that I have spawned one just below that.

There is another method but I have not had much luck doing it myself. They can spawn from monster blocks which are in end portal dungeons.(non-silk definitely required)

I'm convinced spawners do not spawn them.
