So I’m looking at completion on LOL.
Ægon at R3 has these stats

When I take on Rulk enrage kills me eventually
At R4 he has these stats

People say you need over 2k. How far over is reasonable, it says he will have 2005 attack will that be enough or should I have a look at my masteries
Finally do buffs like fury etc increase the timer as well or is it done on base attack only?
