Some of the strongest shouts have been made a bit weaker, but overall some weaker shouts have been buffed. Damaging shouts are truly a force to be reckoned with, especially when turned against enemy dragons.
50/75/100 stat boon over 2/3/4 minutes instead of 75/175/300 over .5/.75/1 minute.
40/75/125 stat restoration instead of 100/300/500.
0.5/0.33/0.25 slow. No longer slows the player (previously slowed by 40% due to a game rule).
Thus previously, gave 1.5x/3x/6x speed. Now gives 2x/3x/4x speed.
Duration increased to 18/24/30 sec (from 10/20/30)
duration increased to 25/30/35
Damage shouts have been buffed a fair amount. Frost breath does more damage than fire but over a long span of time. All 3 are super-effective vs dragons
Fire/Frost Breath/Cyclone III cooldowns reduced.
Marked for Death III reduces slightly less armor rating.
Significant reduction in cooldown times.
