Tried putting fastest everything on my GBA, ran him at speed 292. Still cannot stop the Acklay from getting Enraged and dropping an AOE. I don't think what I am attempting is possible.
When the cooldown on the Acklay ability Terrifying Roar expires, it roars, becomes Enraged, summons up to 4 more Jedi, and removes 75% TM from all enemies. Since it gets to use 2 abilities every turn, it then immediately uses its AOE. I don't think you can stop this from happening, regardless how fast your Alpha is.
I have not been able to time this right yet, but I'm thinking that using Sun Fac Spiteful Strike to inflict Blind on the Acklay right before it roars may be the only way to avoid this AOE. Suppose this means Sun Fac needs a speedy build to increase the chances of getting to use the ability at the right moment.
Something doesn't seem right though. The first time I tried to take down the Acklay I got it to nearly half health before it Enraged. Haven't come close since. Last time I remodded for more speed and could barely damage it once protection was gone.
