So yeh i recently got kog and was trying out abunch of dif builds like Chalice, Madreds or Frozen Mallet, and ect and tried going with Archangels staff instead of chalice but still not sure. or should i just go hybrid? not sure which way to build him since last few patches.
then get boots of speed (ur gonna build these into sorcs eventually)
if ur doing well u can go straight to sorc boots for early magic pen. but i find myself going to the next item next for mana regen
the next item is Tear of the Goddess (which can be converted into a arch staff late game)
after u get doran/sorcboot/tear i straight up build a bloodrazor. this will destroy basically anybody that gets close to you if u pair this item with ur W ability.
ur now in late game, i usualy get the arch staff for a AP boost, or u can go with frozen mallet for mroe survibility. if u think ur doing fine with hp, get a rageblade for more damage --- PSN: Nate_the_Great8 LoL: Nate the Great8
The AD/ AP builds both have merit and will work over the enemy team. If you truly wish to build Kog amazingly, just watch what the enemy team does. If they go heavy defense and you want AD go last whisper. If they go heavy defense and you are AP enjoy the speedy kills on all their champs. Both builds are very viable, but no matter what build you use make a frozen mallet for the speed reduction and always attempt to have both the blue and red buffs. (by the way) I noticed Kog generally finishes his builds earlier than some champs (by all means, don't forget to buy the 3 buff potions when your item sets are full)
My AD build of choice: (not in any major order, just boots and phage always first) Boots of Necessity Phage--->Mallet later Ghost blade Madred's Blood-Razor Bloodthirster (this item is dependent, get survivability if your being focused (GA or Leviathan) get more AD if your not focused (Starks or IE)
My AP Build of choice: (first two items are a must) Boots of Necessity Phage---> Frozen Mallet later Madred's Blood-Razor Rage-blade Nashor's Tooth Dependent on enemy team (if going MR build Void Staff) (if they are focusing you , build survivability like leviathans or GA) (if you want more damage go archangel's) Like always grab the Golem and Lizard buffs when you can.
Masteries I use are 9/0/21 grabbing magic pen and cool downs in offensive, grabbing ghost bonus utility buff time, extra exp and lower dead time. Increased movement speed is a must and shorter cool downs + the final ability for the summoner shorter cool downs. I usually run Cleanse + Ghost, but Ignite + Ghost is worth it as well as Heal + Ghost.
Remember my build isn't the be all end all of builds for Kog, experiment with him. This hero is in a very good place. He plays on the squishy side and yet when you play him properly , the enemy teams carries+ support will melt in your hands(mouth?)
