Runic Stone

[kaply]

Wanted some clarifications on what this skill does.

The english text says Each Mind Rune gives additional Might and Magic Runes to the hero. +10 runes of Might and Magic.

What I can see is that when I put a point into it, I definitely get +10 runes of Might and runes of Magic. I also noticed that when I obtain Mind Runes sometimes I also get the equivalent in Might/Magic Runes. So the questions pertaining to this talent:

1. Do additional points in this talent boost the amount gained? So at rank 2, would getting one Mind rune also get me 2 Might/Magic Runes?
2. Also what conditions does the conversion work under? Ground loot, container loot, gear loot (I'm assuming there's an item that does something like 50 battles get 10 Mind Runes), quest loot, and level up.
