Brick walls in small vaults weakened

Livestock Brading
Brick walls in small vaults weakened:
BW receives it full soak and "Can only be rammed" condition when there's a certain amount of bricks in the village claim, say 1500. Initial corner posts counting as something small, say 150☼ (☼ = Units), to prevent hearth vault makers from just setting corner posts in the back.
This is to prevent the 4 Corner post, 6 statues and 30 segments vaults that can be easily made in a mountain. If the vclaim doesn't has a large enough BW, It soak becomes the one of a strongbox, discouraging the vault usage and enforcing criminals to get their HF in a large village that would have their BWs at full strenght.
+ Encourages village style
+ Easier for Vaults to be attacked
+ Prevents Near Invulnerable vaults.
- Thinking of values the walls needs to be fully operational.

Livestock Branding
"The act of marking livestock with fire-heated marks to identify ownership has origins in ancient times". -Wikipedia

Basically, a villager uses a Branding Iron on livestock, marking them show the name of the Village in their cattle info, permanently. When a branded animal is outside the village claim, it's just marked as "Missing", until it reenters the village or it's marked as dead by the LS/Chieftain.
Example:
Village A brands a cow. Village B raids A and steals the cow. Village A later breaks into B, located the cow branded by them, they're allowed to take said cow without leaving any scents at all.
