Obtaining
It exists in the creative inventory and can be obtained via commands. It also has a recipe like typical slabs.

The slab works similar to normal TNT, with the added bonus that it can also spawn anvil blocks above the player above detonation.

ID
The double Etho Slab has ID 159, and the regular Etho Slab has ID 160.
