Mixing levels and pawns in enchanted devices is a little confusing (and may vary from saga to saga). In the past, I only looked at the levels, 43 here and 35 there and usually my devices would have 7 or 8 levels left over. But then, when I was looking at something else, I wondered if my interpretation was wrong - should I be looking at whole pawns of vis instead of individual levels.
1 pawn = 10 levels of effect.
so if I open an item for 12 pawns of vis it can hold 120 levels of spells.
So, I can put in two effects - one of lvl 65 another of lvl 55
They both add up to 120. But when I actually do it with pawns of vis, I am putting in 7 pawns and 6 pawns, so my device now has 13 pawns of vis in it.
So, I can look at this in 2 different ways:
levels are all that count - if you enchant something at level 65 you are actually putting 6.5 pawns of vis into an object, the other half a pawn is wasted.
pawns are what count - if you enchant something at level 65 you are putting in 7 pawns of vis into the object, so there are 5 pawns left free. Ignore the "levels" of the object. If you opened it for 12 pawns of vim, you can only put 12 pawns into it. How efficiently you use those 12 pawns is up to you.
What do you guys think?
