IDEAS FOR RYZOM

I've made this grid with Zagh's comment in mind, but you're right, counting transmutation is confusing and unneeded.

So only first row is useful, with a little change.

| 50 > 100 | 100 > 150 | 150 > 200 | 200 > 250 |
| 75%      | 57%       | 43%       | 33%       |

I persist in thinking that an unnatural matter must behave differently from a natural matter, especially in terms of fragility.

An advantage must be maintained in having a high-level outpost.

For me the idea is simple. The more one transmutes a natural matter to increase it in quality and the more it will be subject to destruction. Hence the interest of having a cross table as presented by Ekoh following my answer.

That's mean that it'll be added 80 derivated mats for the 8 OP mats, it's substantial !

1 Mats q50 1 original
2 Mats q100 1 original + 1 transmuted
3 Mats q150 1 original + 2 transmuted
4 Mats q200 1 original + 3 transmuted
5 Mats q250 1 original + 4 transmuted

Unless it's possible to add as a descriptive information the number of mats transmutation.
