I find it funny when I try to blow the walls of the lab with dynamite it takes more bundles than with fertilizer bombs.
I literally spent 7 bundles of dynamite vs 4 fertilizer bombs to blow a hole from the inside.
Speaking for land mines, I think it may be worth a shot at putting some kind of bone health rather than total HP for a certain limbs, so while your armor may absorb the main brunt of say the blast or shrapnel it won’t stop all the force and some damage might go into breaking the threshold for fractures. That way we can’t go blundering into mine fields and step on all of them like they’re made out of Legos or be able to get launched by hulks and walk it off like it was just nothing.
