The goal of ShakaUVM's D&D Combat Calculator is to discover what combinations of feats, equipment and power attacking yield maximum damage. It will calculate, based on your combat stats, the average damage you will deal vs a range of ACs, your ideal power attack numbers, the average you will deal with ideal power attack, and your maximum damage.

Many situations can be simulated using the generic fields below. For example: if you use a masterwork weapon, give it a +1 enhancement and subtract 1 off its average damage. About the only things you cannot simulate right now are natural weapons and weapons that deal extra damage on crits (i.e. Icy Burst). Support for these might be added in at some future point in time.

The Combat Calculator attempts to error check your input, but due to the complexity of the game it is not always possible to tell if the input is actually in error. For example, Greater Weapon Focus is normally limited to 8th level fighters -- but Order of the Bow Initiates get it for free. Likewise, charging normally only allows you a single attack -- but Cavaliers can make Full Mounted Attacks. So, the combat calculator will helpfully select "Only 1 Attack" if you are charging, but you can still unselect it manually if you are playing a Cavalier.

It will work with both 3.0 and 3.5, but you'll have to manually enforce the appropriate rules (for example, it won't complain if you have keen and improved critical on a weapon, which is legal in 3.0 but doesn't work in 3.5). Questions or comments should be sent to ShakaUVM (on Reddit).
