Lesser. So I'll have +4 EXP from flaws, which is fine for me.Do you mean it has 3 damage +4 damage from its master craft for a total of 7? Or am I still suffering some penalty here?

Ah. Lesser fear its only a DL 15 Concentration Roll then. Also the blade has a +4 Damage modifer thanks to it being Master Crafted (all Master Crafted Weapons deal +1 Damage and get +1 to Attack/Parry Rolls), your Might adding another +3, so whenever you hit you deal an additional 7 Damage.

So you are no longer suffering any penalty if your Might is 3.
