New Item, Bracers of Archer's Strength

[Bladesong]

Still way to good for casters (who are likely to have maxed Concentration).

Be imaginative. Maybe it only works for single classed archers or requires the feats precise shot and point blank shot, etc. Sorry, the money thing with magic items just annoys me.

Says who? The RAW says nothing about tying the size of the bow to a maximum STR modifier. There is nothing in the RAW preventing you from crafting a Size Tiny Mighty (+100) Composite Longbow with a span of, oh, a foot or so.

Perhaps said bow is alloyed with adamantine giving it an unusually powerful draw.

There comes a certain point when you can no longer use the "D&D is not realistic" excuse. Most of D&D is realistic, and part of that is that you cannot have tens of thousands of pounds of force in a bow with a span of one foot without epic-level magic. I prefer to keep my suspension of disbelief good and close.

This is why I prefer Tinker's Discussion of Bows (link to PDF). It gets rid of silliness like +100 mighty bows with a span of 1 foot.

I still submit that the only way to balance this item at the 5,000gp price point is to have it negate the -2 to hit for not being strong enough, but *not* grant them any strength bonus to damage beyond their natural strength score.

Fair enough. I'm not to stuck on the 5000 price. It's just the idea is that one thing grants you all the strength you need, and an exponential pricing scheme would only work if there were multiple levels, which goes completely contrary to the idea.

Even if people were to think this was an epic level item, that would make sense. So, rather than tone it down for the 5000, how much would you price it?

Quite frankly, I don't think it's possible to balance at ANY price as originally written. It either needs to grant no extra bonus damage (from strength), be capped at a particular bonus (and priced appropriately), or bows need to have an abitrary cap on possible damage at each size category. In the last case, the gloves would also need a size category restriction and would need to be priced based on a strength item for the maximum possible bonus they can grant.

If you're going to write something that can give a +100 strength bonus to damage (though as written, there's no reason to stop short of the most expensive bow you can afford--if you've 100,000gp to spend, a masterwork mighty [+996] composite longbow would be the item of choice--it needs to be priced appropriately. If it is restricted (either directly or by restricting the maximum damage bonus of a bow), then it needs to be priced based on the maximum damage possible after the restriction.

Even if people were to think this was an epic level item, that would make sense. So, rather than tone it down for the 5000, how much would you price it?

Well, that depends. What's the maximum STR modifier for bows in your campaign?

Also note (extreme examples aside) that unless you've got epic-level master bowyers that for all intents and purposes mighty bows may as well be limited to +10. The craft dc for mighty bows is 15+2*Mod, so a +10 bow is DC 35. +20 would be DC 55, requiring either an epic bowyer or a warehouse full of assistants.
