What is the limit on Mighty pertaining to Ranged Weapons?

By way of background, I'm familiar with the standard Composite Longbows which follow a logical progression of Attack Bonuses coupled with the Mighty property: +1 Composite Longbow (+1 Attack with +3 Mighty), +2 Composite Longbow (+2 Attack with +4 Mighty), . . . +5 Composite Longbow (+5 Attack with +7 Mighty), +6 Composite Longbow (+6 Attack with +8 Mighty), . . . etc.

However, since the mysterious crafty Dwarf limits his Longbows to a (+5 Attack with +5 Mighty), I am unsure about the maximum Mighty bonus. Honestly, I half expected a +7 Mighty to be possible along with the +5 Attack bonus. That being said, I am perfectly content with whatever the moral majority and/or Gods decree. . . I just want to be absolutely, positively, no-doubt-about-it, for certain, sure about this little detail.

I have not limited the Mighty property the way I have with attack bonus and enhancement bonus. You can have as much as the toolset will allow. Maybe your bow is made of layers of steel instead of wood.

I limit attack bonus and enhancement bonus just because of certain creatures with epic damage reduction.

The dwarven wizard limits his just because I didn't script a way for DMs to add every single possible variation on every single item property (I did give them around 500 properties they can add).

Thank you Amethyst for responding.

I had no idea there were so many scripts enabling DMs to be... the terrific DMs that they are.

Of couse, now I'm torn between spending my precious Voucher money on a Composite Longbow (with more Might than +5) or having the crafty Dwarf build the one he offered - which is pretty darn good. Decisions, decisions.

If you have the STR for it, more mighty is always good since it adds a flat number to your damages rather than a variable dice roll worth of damage
