Uncanny Accuracy

(Epic Level Handbook, page 68, DnD 3.0)

[Epic]

You can ignore anything less than total cover or total concealment when using ranged weapons.

Prerequisite

Point Blank Shot, Precise Shot, Spot 20 ranks, DEX 21

Benefit

When throwing or shooting a ranged weapon, you can ignore any cover bonus to the target's AC (up to a maximum of nine-tenths cover) or any miss chance conferred by the target's concealment (up to a maximum of nine-tenths concealment). If the target has total concealment or total cover, the AC bonus or miss chance applies normally.
