I'm still a newb and I don't think I understand bonuses to weapon damage properly.
By this I mean like how a scimitar does 1d6 damage +4 if you have a strength of 18.
My question is- what affects weapon damage? What applies a bonus?
A guide to the Magus I have read seems to have a sample build where weapon damage is:
At level 1: 1d6+0
At level 3: 1d6+6
At level 6: 1d6+7
At level 11: 1d6+17
This build is using a scimitar with a strength of 11 and receiving weapon spec at level 11 and power attack at 9.
My question is, where is the +6 at level 3 coming from? What happened between level 6 and 11?
