Sculk Stabber/Sculk thorns

Is a sculk-related block that can be found in sculk biomes. Catalysts have a 3% chance of spawning them

Appereance

 * Stabber: is a bone-colored block with several holes on it, simiar to the earlier concepts of sculk (the trypophobia one), with some sculk peeking out of them, it also has sculk patches around it, similar to the evoker.
 * Sculk thorns: they look like small brownish white stalagmites with some sculk on them

Sculk stabber:
Whenever the receive a vibration/redstone signal, they activate, lightning the holes on them and summoning 3-5 spikes on sculk blocks in a 5x5x5 area centered around it. has a 2 second cooldown.

Sculk Thorns
if they are activated, they will pop up and doing 3-5 damage to any entity above them (except the warden of course), they deactivate 1 second later. they can spawn in random sculk blocks the sculk stabber detects.

Obtaining

 * Use an iron pickaxe to harvest the sculk stabber and use it as your personal home defense, they are the only sculk-related blocks that can be mined better with a pickaxe
