*whitelists for frocewrench*It's about as tough as Bedrock. I saw about, since Bedrock is hardcoded to be unbreakable for in MC(not that a creative mode player obeys that rule), and it's very hard(if not impossible) to make something as unbreakable as bedrock.
...That being said, one can find ways to move it without breaking it if one is clever.
HAAAAAAAAAAAAAAAAAAAAAAXIt may be fixed but about a month ago I ran a Mekanism digital miner and got a water spring block. It freaked me out because I thought the miner had drilled up some bedrock. So there's a thought.
Awakened ichorium?It's easy to make blocks as unbreakable as bedrock - anything with a negative hardness is unbreakable, the end.
Actually, the Awakened Ichorium pickaxe doesn't destroy bedrock the way you would think. Thaumic Tinkerer makes bedrock breakable by it, not the other way around. In reality, the Ichorium pick is about the strength of a diamond pick in that there are blocks it can't break(Higher tier Metallurgy ores) that other items can(such as an Mekanism Atomic Dissassembler.). Just FYI.Awakened ichorium?
