Ehhhhhhhh A bit of a glass cannon Urgot to me. Dust up the runes a bit, armor penetration scales much, much better late game. Unless you're just putting what runes you have, in which case I can understand.

pretty solid, like it, good work, agree with thw last whisper, but just that +1 from me

I think this is a good guide but shouldn't you get a trinity force since you will be spamming your acid hunter all the time? Gonna try hextech gunblade to see if it works.

The main thing about the manamune it makes you have enough mana to spam your abilities without worry, yeah i put in the last whisper and it helped me a ton with just plain hitting more especially on tank's or tanky dps, while i find a brutilizer ultimately becomes less useful over time the manamune just keeps getting stronger.

For the mere 600g more the HexTech Gunblade is a very viable alternative, especially because it already starts with quite a good spell vamp and life steal, while as that late in game bloodthirster will most likely not get the stacks it requires to become useful thanks for the tip :)

this is a prity damn good guide. the only place i would alter it would be insted of the manamune get a brutalisor for the armor pen and cdr and if u also have cd runes u can get off 3 q's almost dubleing the amount of harass damage u can put out. i also think you may want to get some tankeyish item insted of the last whisper cuz u only really need that item when fighting rammuses and not many people play him so it is sorta like my defalt thing and it gives you wayyy more survivability in team fights cuz ur guna get targeted alot when they c ur crazy damage. for new players id also switch out 1 of the helth pots for a mana pot cuz it can some times be dificult to land the grenade thing or E.

You only have 9 armor penetration with the given build. All of your damage is physical. Definitely take Last Whisper - I guarantee you your damage will skyrocket.

Test out Hextech Gunblade over The Bloodthirster and tell me how it goes.
