Random Magic ability

First, 10% random means that about one in ten mages of that type are going to be more powerful in magic. The paths available from a random depend on the mage, and there may even be multiple randoms with multiple chances. Arcoscephale Mystics, as an example, have Astral 1, always one of Fire, Water, Earth and Astral (100% chance), and 50% chance in each of Water, Earth and Astral.

100% FWES
50% F
50% W
50% E

Or, maximum of 2 in each of the four paths, often only 1 in two, perhaps three paths, and in theory a lucky Mystic could even get 5 picks in magic.

Is this correct? I was assuming that, say, 50% FWE meant a 50% chance of an additional magic point, which would be either F, or W, or E - but that it was impossible to get more than one of these (kind of like it works with the 100%).

When you have 50% FWE then you can just get one of them. But Arcos mystics have randoms of 50% each (not 50% FWE but 50% F, 50% W and 50% W) so you have a 12.5% chance that the Mystic gets all of them.
