Health of structures in caves, the foundation wipe dilemna
In my case, I can't stand foundation wipes. They cause people to leave the server. However, if you raise the health of foundations to reduce the desire to foundation wipe, cave bases are super strong because players can close off entrances almost entirely with foundations.

Is there a way to provide control of foundation health in caves differently than foundations above ground?

This would be very helpful.
In general - nope. You can control only general health multiplier of foundations.

Only thing here - we can increace damage on them in XXX times via hooks (not the best, but only solution)
I'm guessing the only thing that would fix this is not allowing cave bases to build foundations 'higher'. Meaning they you can build foundations at the low position, but not the high one.

or just multiply damage so they will get same value (only for foundations)
