Into The Wild
When making dragonhide armor, you can combine the hides of two dragons. The combination is basically as follows: Take the larger dragon as the “base” armor. Then, for each size category above medium of any OTHER dragons, reduce the required size difference by 1. For example, with one young green dragon, you can make full plate for a creature Diminutive or smaller. With 2, you can make full plate for someone Tiny or smaller. If you want to combine the hides of DIFFERENT color dragons, the same thing applies, but the armor costs an extra 50% more per extra color (so instead of 2x, 2-color armor costs 2.5x, 3 color would be 3x, etc) the cost of normal armor, not 2x, but it is immune to 2 (or more) types so can reduce the cost of either. Same color, or two colors with identical immunities (Brass and Red for example) doesn’t alter the price at all, but realize that doing that will almost invariably make EVERY dragon hate you as you are wearing both good and evil dragons!
