The winning plunder goes to the OSF side of the war, by making the regular clan forfeit near the end. I'm surprised how do they grow since war tax is a small amount of a hit so 1bil is like 300mil.
If it's done right, the OSF loses less money in hits than the amount of war tax he/she gets at the end.
Okay, I have stumbled over this question as much as the next guy. But I finally understand. A osf makes money when dropping pots players hit u and they only take the money u had in your bank, but the player hitting makes her/his regular plunder. Here's in example. I hit an osf and they only have 21k out, but i still make my standard 30m per hit. The other way they could do it is by pinning their spy's to right above the pinned mark and then having money out. Whenever you hit a almost pinned osf with money out you don't take the full plunder you would if their troops were full. If you still don't understand post on my wall.
