Simple suggestion that blocks from the mod should be water-loggable. Also standing torches/fire pits/fire goblets would be nice additions to a dungeon.

Minecraft Version; 1.20.1
Forge Version; 47.2.16
Dungeon Blocks Version; 2.0.0

From what I have tested only the following blocks have their required tool assigned;
-All blackstone variants minus the corbel, ledges, barred windows, & barred window facade variant.
-All deepslate variants minus the corbel, ledges, barred windows, & barred window facade variant.
-All Obsidian variants minus the corbel, ledges, barred windows, & barred window facade variant.
-Dungeon Lantern

And from what I was able to find the following do not have recipes
-Both hay patches
-Both sewers
-All 3 greek blocks
-All stone blocks minus the barred window, the barred window facade, the ledge, and the corbel

In mc1.18.1-f39.0.0-v1.1.0 a significant portion of the blocks (deepslate pillars and sills to name two) don't drop anything when broken.

I've noticed that when building with these blocks, there isn't a preferred tool that can be used with them. Instead of saying block X needs a pickaxe, it's just blank. So when trying to break them, it's almost like trying to break it by hand. I took a look and all of your blocks are stone-type variants, so I'm hoping it'll be easy to just set them all as being able to be harvested by pickaxe?
