I have been playing some HARP with my son and we finally got some characters to the point where we can do some scaling up of spells for greater affect.  In this process I've noticed that the casting penalty for scaling up a spell in HARP seems to be too steep when you consider that you also have higher ranks giving less increase to skill.  Anyone else ever run into this issue?  I brought this up on the HARP forums on ICE and thought everyone was a little too much in tune with the party line and not willing to consider there might be a flaw in the game design.

Looking at the armor rules and have a couple of questions for clarification.
Impedance Penalties?  Do they stack, my assumption would be yes but perhaps you are supposed to take the worst one.  If they do stack I can't see any semi-adept (such as the Ranger) being able to wear armor and cast spells, it would take too many spell points.

Manuever Penalties?  Do they stack or do you take the greatest one, I assume they stack.  Also for the bracers, greaves, etc. that have a - for penalty does that become -1 if untrained or do only the zeroes for torso armor change to -1 if unskilled.

Lastly (for now) can you wear only say bracers and greaves and no torso armor and what benefit would it have if your opponent was targeting that location with a called shot?

There are a number of Talents in Libram Novus #3 that state you need the Archery Talent as a Pre-requisite.
I can't seem to find an Archery Talent anywhere.  There is of course the Archery Combat Style but I don't think they mean that.  Could they be referring to the Talent Extraodinary Aim?
