Call for ArM5 Errata

[David_Chart]

@ezzelino

Possible error: Discovery yields 15xps in an Ability, but 3xp in an Art. That's probably an error of the conversion from older experience systems, where 1 "old" ability xp was worth 5 "new" ability xps, and it should be 15xp in Arts too.

In ArM4 it was 3xp across the board, which was accurately converted to ArM5. The fact that you get a bigger bonus for Abilities is explicit now. It's possible to spin a plausible story for why this happens, and I think that's good enough for this table.
