When i want to break the Blocks of Demum Ornamentum it needs very long to break it.
I have JADE Mod installed and there is no tool i can use for breaking it faster.

Duplicate of #76 and #60

The issue is that they are exactly the same block, independent of the materials used to make it. Using a pickaxe is strange for wooden framed blocks, and an axe is strange for stone framed blocks

so breaking a block taking 10 seconds each is solution?

No, both of the linked issues provide a solution. I just explained the reason of the issue

it seems the axe is the right tool, at least for the panels. i'm using the one probe and although it says there's no designated tool, when i hold the axe it changes to a check mark and the block seems to break faster
