Resizing & Endless Ammunition + Enlarge Person


Rules Questions


I have been playing a character who makes regular usage of Enlarge Person on themselves lately, and am looking to add some enchantments to their ranged weapon to aid them when melee is either not an option or a terrible idea...

Now, I am well aware that projectiles revert to their original size after they leave your possession while under the effects of Enlarge Person. That is not in question one bit... however...

1) Would a Bow with the Endless Ammunition enchantment create Large arrows when affected by Enlarge Person, or would it still create Medium Arrows that are enlarged only for as long as it takes to release them?

2) If I invested in a quiver full of Resizing Arrows, would they remain enlarged after fired until 1 round later (as the enchantment states) or would they still be reverted the moment they leave my possession as a result of the Enlarge Person spell? Basically, which effect takes priority here?

3) If both of the above still result in firing Medium sized arrows, would a Resizing Bow with Endless Ammunition yield the desired result of Large sized arrows?


1) This would create non-magical large size arrows that stay large size when they are fired.

2) Enlarge person would take priority unless you picked them up after the spell was cast on you.

3) Yes.

3) The resizing bow resizes to the size of the creature, but if you have it in your possession when you cast enlarge person it is already large, so it will not resize.
To get the desired result you net to put it down, get enlarged and then pick it up. That way it resizes.

Good if you have time to prepare, less good if you have to do that in a hurry.


You could get a Size Large Bow or Endless Ammunition. That way you can drop the Bow as a Free Action, Enlarge as a Swift Action (I like Living Monolith), pick it up as a Move Action, then cast Gravity Bow on yourself as a Standard Action. Then the next round your Large Orc Hornbow of Endless Ammunition is up to 4d6 Damage/shot.

I still think the cheaper method, though is Mark Seifter's method: carry around a quiver of Size Large Arrows and execute the above procedure.

Remember to put Adaptive on the bow. For 1,000 gp it is worth it, especially if you will change size often.


The solution I came up with is to go ahead and invest in an efficient quiver and load it up with both medium and large sized arrows to use. In order to save a bit on cost I went ahead and had all of the arrows made out of stone(see the bottom of the linked page) which reduces the cost by 1/4. The net result is that instead of my large arrows costing double they instead cost half.

Since all of the arrows are in an extra-dimensional space they remain unaffected by the enlarge person spell meaning I don't have to worry about the arrows changing size after I shoot them. As an occasional archer this is more cost effective than putting the fairly expensive endless ammo enchantment on the bow.

Honestly, making arrowheads from stone and saying that the arrows cost 1/4 in a pseudo-medieval/renaissance society where practically no one knows how to work stones seem an exploit. Low-quality metal arrowheads can be made rapidly, stone arrowheads require time and precise crafting to be effective. But the shaft and fletching of an arrow are as important if not even more than its head. So, decreasing the production cost of the arrows because a small part is made in cheaper materials that require more work is only an attempt to play with the rules.

Strictly RAW, the arrowheads aren't weapons, they are part of ammunitions, so they aren't even subject to "Stone weapons cost a quarter as much as base items of their type".
If you can find a separate price for arrowheads you have a basis to say that the arrowheads cost 1/4 of the normal price, but not all the arrow.

If the DM wishes to disallow all primitive materials because they feel that they are exploitative that's fine. by RAW a "stone weapon" is a weapon where all of the parts that would normally be metal have been replaced with stone. All of the primitive materials are the same way. The person writing about them decided to use the term arrowhead instead of arrows throughout, but they mean the same thing. If you don't believe me compare obsideon vs stone. Stone calls out that spears can be stone weapons and that they cost 1/4 the normal cost. Obsideon calls out spearheads and states that they cost 1/2 the normal cost. The glass material talks exclusively about dagger blades and arrowheads It then goes on to state that glass weapons cost 1/2 the normal cost. Bronze talks about spear points, axe heads and arrowheads.

The reason they call out the weapons this way is to keep someone from thinking that a bronze axe is an axe made entirely out of bronze. This is why you can even have bone studded leather. It's not armor made entirely out of bone, the studs are made out of bone instead of metal, everything else is still leather.


Get a large bow of resizing with endless ammunition and it should solve your problems. Since the weapon is actually large, when you grow due to enlarge person the enchantment basically turns off. At that point it is actually a large weapon so the ammunition does not change when it is fired. You also get the effect that 1 round after you fire the arrows when normal size they become large. RAW probably not going to do anything, but still kind of strange.

This would also allow you to use gravity bow without any of the questions of stacking with enlarge person.

A size Medium Character holding a Size large bow who casts Enlarge Person will be holding a Size Huge Bow and will suffer that oversize penalty. She will still have to do the thing where she drops the bow, Enlarges, then picks it up again, as I was saying.


A large bow with resizing becomes a medium bow when used by a medium creature. When enlarge person is cast the person becomes large and the bow reverts to large. Since the bow is actually large the ammunition does not shrink when it leaves the bow.

So, you are talking about spending an additional 4000gp for the Resizing enchantment, and a +2 equivalent enchantment in the form of Endless Ammunition. So, minimally, we are talking about a +3 weapon +4000gp, so 3>3 = 9 X 2000 = 18000 + 4000 = 22,000gp magic item?

At 22,000gp, it had better work! Honestly, though, just carry around a quiver of large arrows! We're weighing a solution that costs like 1gp as opposed to a solution that costs 22000gp. Surely you can think if a better way to spend that money!

Take the money you save to buy yourself a nice Portable Hole, then you can fill it from top to bottom with arrows!

An Efficient Quiver is an extra-dimensional space. The contents probably do not increase in size when you cast Enlarge Person because they are not on your person, but rather in that Extra-dimensional space like Rope Trick or Bag of Holding or a Portable Hole. And if you really want, you can cast Abundant Ammunition of your quiver, or get someone to, or use a Wand of Abundant Ammunition. But honestly, arrows are not that expensive, are they?
