just thought I'd post this as a resource for any game that might be replacing the d10 with 2d6 (seems to be one of the more common ideas on changing up the dice mechanics) - just a table for random vis finds/sources...
11-12 Infernal Vis, re-roll to determine Art, ignore realm results
13-14 Faerie Vis, re-roll to determine Art, ignore realm results
65-66 Divine Vis, re-roll to determine Art, ignore realm results
a couple of nits- and I do think this is a great place to start, but
I think alternate realms should be more common that 1 in 18 apiece
it leaves out other - admittedly obscure forms of vis like combination (TeFo) vis or objects of virtue
I'm thinking something like if the first die is a 1 then faerie vis, 21 through 24 is infernal vis, and 25 or 26 is divine vis, leaving 24 possibilities, which should include a sub table for obscure vis, and maybe some degree of saga customization for relative scarcity of differing types of vis.
