Thundering rage

Type of feat: general (available every three level-ups) (epic)
Prerequisite: epic barbarian 21st level, greater rage (4x per day), strength 25+

Specifics: Any weapon the barbarian wields while in a rage does an additional 2d6 points of damage on a critical hit. There is a 50% 25% chance for a creature hit by one of the barbarian's weapons to be deafened for 3 rounds.

Use: automatic

Notes

• Requires Hordes of the Underdark.
• This feat's description incorrectly lists "epic barbarian" as a prerequisite. Instead of being an epic barbarian (21 barbarian levels), this prerequisite is actually a combination of being an epic character (21 character levels) and having the feat "greater rage (4x per day)" (obtained at barbarian level 15).
• There is a fortitude save against the deafen effect with a DC of 20.
• The in-game description incorrectly lists the chance of deafening at 50% when the chance is actually 25%.
• The additional damage is implemented as a massive critical item property, one which will not be applied if the weapon already has such a property. (In particular, it stacks with overwhelming critical.)
• This feat will affect (only) the weapon(s) equipped when the rage is started, and the off-hand weapon (if any) will not be given the ability to deafen.

Custom content notes

• This feat is implemented by the CheckAndApplyThunderingRage() function located in the script x2_i0_spells. It is called at the end of the rage scripts via CheckAndApplyEpicRageFeats() (also defined in x2_i0_spells).
• 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.
