Improved sneak attack

Type of feat: general (available every three level-ups) (epic)
Prerequisite: (rogue) sneak attack (+8d6), sneak attack, blackguard (+8d6), or death attack (+8d6)

Specifics: Add +1d6 to your sneak attack damage. This feat may be taken multiple times, to a maximum of +10d6.

Use: automatic

Notes

• Requires Hordes of the Underdark.
• As of patch 1.66, a bug prevents this feat from working for an assassin who does not have sneak attack or sneak attack, blackguard. The improved sneak attack feats are still selectable for the assassin, but they will add nothing. If the assassin has even one die of sneak attack damage from rogue, blackguard levels, or item property then improved sneak attack works as expected.

Custom content notes

• A custom class must have this feat in their feat list, or that class will not be able to select it as a general feat.
