(please include information of what you did, that lead up to the bug, what you expected to happen there, and what actually happened, then move on to describe below:)
When I use the ability blinding speed, the cooldown is set as 7 minutes. I have 10 levels of swashbuckler, and 16 levels of assassin. The cooldown should be reduced according to this formula (from wiki).
Blinding Speed: Is now an Instant action and an extraordinary effect (not affected by antimagic). Duration increased to 3 turns. Has unlimited uses per day, but 8 turns of cooldown period. The cooldown of Blinding Speed is reduced by 1 turn every 6 combined Assassin, Harper Scout, Invisible Blade, Rogue, Shadowdancer, Swashbuckler and Zhentarim Operative levels. Rogue levels are not required for this bonus to trigger.
Steps to reproduce the Bug:
Anytime blinding speed is used
Expected Result:
A cooldown of 4 turns (8 turns base - 4 turns from my combined 26 levels of swashbuckler/assassin).
Actual Result:
The cooldown is listed as 7 minutes (7 turns)
