I came up with a crossbow sniper build a while back that you may get some mileage out of. It's not as effective as the above rapid fire build, but the looks on your friends' faces when your crossbowman drops
two dozen dice on the table for
one damage roll will be priceless.

Use a heavy crossbow sized for a large creature when you can. Going from 1d10 (5.5 average damage) to 2d8 (9 average damage) for -2 attack is
slightly more efficient than Deadly Aim. Purchase a wand of
gravity bow once you have enough UMD to make it reliable (don't forget to get a masterwork tool). With gravity bow active, your crossbow is now at 3d8 base damage. If you can get an enlarge person spell cast on you, your crossbow goes to 4d8 for another -2 attack (-1 size, -2 Dex), which is a 4 point net gain in damage - this is
less efficient than Deadly Aim, but it gives you more dice to roll, which is fun.
Seven levels of crossbowman grant you +1/2 Dex to damage and denies the target their Dex to AC
if you ready the action to fire. This is not such a huge deal because (a) you can just ready the action to trigger
just before the next initiative and therefore keep your turn order and (b) Vital Strike and its kin use a standard action and
can therefore be readied. This is why we went through the trouble of boosting your base weapon damage.
Modifiers | Base (avg) | VS | Imp VS | Greater VS |
Heavy Crossbow | 1d10 (5.5) | 2d10 (11) | 3d10 (16.5) | 4d10 (22) |
Large Heavy Crossbow | 2d8 (9) | 4d8 (18) | 6d8 (27) | 8d8 (36) |
Lrg Hvy Xbow +gravity bow | 3d8 (13.5) | 6d8 (27) | 9d8 (40.5) | 12d8 (54) |
Lrg Hvy Xbow + gb + enlarge person | 4d8 (18) | 8d8 (36) | 12d8 (54) | 16d8 (72) |
If you can snag any other size boosters, I highly recommend it. Size modifiers for weapon damage really start to accelerate as they go up. For example, if you could get just one more size increase beyond enlarge person, the base weapon damage jumps from 4d8 to 6d8!
Then start stacking rogue levels for sneak attack dice. Your basic combat strategy then looks something like this:
- Target beyond SA range but less than (SA range + your move speed): Use one move action to get within 30 feet and use option 3.
- Target beyond (SA range + your move speed): full attack with Rapid Shot against low AC, readied VS against high AC.
- Target is within SA range and has Dex to AC: readied VS to deny target's Dex to AC for multiplied base damage +1/2 Dex + sneak attack.
- Target is within SA range and is denied Dex to AC: full attack with Rapid Shot base damage + sneak attack.
In all of the above, use Deadly Aim at your discretion - it stacks with everything.
