Ok, Im still fairly new to Pathfinder, and I was never big on 3.5. So I think that my issue is that enchanted weapons are unfamiliar territory for me.
I love the Magus. But I think i have misinterpreted how the Arcane pool feature works, so I'd like to clear it up.
I used to think it worked as follows. That I could only give a weapon a +x/x bonus of +5/5 with the weapons own enchantment bonus. So a +5 Acid Burst weapon wouldn't be able to benefit from adding +X/+X. And adding properties was separate. I.E. I spent a point for the +x/+x and another point for say Keen.
Buuuut from what I have been reading today it looks like it is supposed to work as follows. I spend one point and one point only to add enhancement based on my maximum +X/+X and it stacks with the weapons existing bonuses.
So at level 5 I can add +2/+2, +1/+1 and Keen, or Keen and Flaming.
And at maximum I can add +5/+5 or I can add +X(where X<5)/+X and an enhancement or a number of enhancements.
Did I get that right?
