CrackedObsidian
by ckeeze
CrackedObsidian changes how obsidian blocks take explosion damage, so a wall of obsidian can be worn down and then repaired instead of being unbreakable.
What it does
Obsidian blocks in the mod have damage stages. Each explosion that reaches a block counts toward the total number of explosions that block can withstand before it breaks, so a raidproof base made of obsidian is no longer completely invulnerable. Explosions above a set strength threshold apply damage, and the radius in which explosions affect obsidian can be changed.
Damaged obsidian can be repaired with a new Obsidian Glue item, which restores half of a broken block. A damaged wall piece can also be replaced one block at a time. Other blocks keep their vanilla behavior. The mod works on client and server, so both sides need it, and it is published for Forge only, for the 1.20.1 – 1.20.5 range.
CrackedObsidian is built for Forge and covers game versions 1.20.1 – 1.20.5, with 1.0.2 for 1.20.5 as the latest file. Its code is publicly available, but the license is All rights reserved, so the code is not open source.
Key features
Damage stages on obsidian
Obsidian takes damage in stages, and the total number of explosions a block withstands is set before it breaks.
Explosion strength threshold
Only explosions above a chosen strength apply damage to obsidian, and the radius of that damage can be adjusted.
Obsidian Glue repair
The Obsidian Glue item instantly repairs half of a broken obsidian block, so damaged walls need not be fully rebuilt.
Single-block wall replacement
A damaged wall can be replaced one block at a time, without tearing down the whole structure.

What the author says
Obsidian is the and all Be all for a raidproof base, but it being completely invulnerable is boring! Now Obsidian takes damage and can be overcome with enough explosives but still takes way more punishment than the other blocks! You can also instantly repair the half broken Obsidian blocks with the new Obsidian Glue…
