You can stack 3 brutalizer items now really quickly on junglers.
Previously, if you wanted to get in on the best arpen cdr ad item in the game multiple times, you had to get:
- a brutalizer, turn it into Youmuu.
- a brutalizer, turn it into Cleaver.
- a brutalizer.
These did stack and overlapped. However, the Cleaver is more of a choice for heavier bruisers: it gives health and a ramping penetration. If you wanted to stack the brutalizers, you had to pay 1663 gold that gave you very little additional assasin power - 25 AD. Now, what happened?
**You can add your Brutalizer to your jungle item for 163 gold. **
Now you can get 100 AD, 30% cdr, 40 arpen, 15 % critchance and a Youmuu active for 5537 gold. That is some pure rapist mode assassin heaven.
As a 
main there is only one thing i can say: UHHHNGGHGYEH
PS: But what about the sustain? Buy the Ranger's Trailblazer, and smite the Krugs as often as possible. With Rengar's ridiculous AS and multiple AA resets, stun every 5 attacks is pretty much half the time. Combined with the stunning smite, you will have NO sustain problems.
Hope it helped. On my way for some ridiculously easy freelo.
