An experienced Phoenix Knight can easy beat a destro.
15 sec before game starts, PK make 2-3 sacri on Destro.
With this way, PK is rdy to activate AI and Destro can't low his HP (for frenzy,zealot etc).
So the game begins.
If Destro start hitting the Paladin, he will lose his CP and half of his life in about 15 sec (remember, Paladin is on AI). So, when Destro has 30% HP, he will activate Frenzy/Zealot.
Meanwhile, Paladin try Shield Slam before Destro has 30% HP.
Then PK, activates Vengeance and then Ultimate Defence and TOL if he has lose some HP.
With too much pdef and heal on him self, destro can't kill Paladin.
If Destro start running until Paladin's AI going down, Paladin start hit with Bow. In About 30-40 sec, the result will be the same. Destro will have half of his HP.
When Destro has 30% HP he will activate Frenzy, zealot etc.
Paladin is not fast, no point to run.
Activate Vengeance and continue hit Destro.
So, Paladin is full of HP and CP and he is on Vengeance and Destro has 50% HP (cause of battle roar).
This is the way i win 9/10 destros in Olympiad Interlude.
Have a nice day
