Say you have a +1 composite (+2) longbow. It would cost 2600, 300 for masterwork, 300 as a composite +2, 2000 for +1 enhancement.
I am wanting to upgrade the bow to have the weapon property adaptive, which is a 1000 cost enhancement. Which would bring the cost upto 3600? Or would it replace the composite +2 and only cost an additional 800?
Do I end up with an adaptive composite +2 bow? How would the two abilities work together? I must have a minimum +2 str to use the bow, but it gives me a damage bonus equal to str mod?
