The first link is in the 0.9.5 version, as you can se, the npcs i hitting have armor, and the damage is being bypassed with no downsides of the damage.
But in second link, the 0.10.0 test build, the internal destruction don't bypass armor anymore, it's a reduced damage.
In the third link is the 0.10.0 test build again. i hitting a NPC with no armor, and the damage now is correct, but when a hti a npc that have 29 armor, the damage is reduced
