Pantheon is a tanky DPS champion that in my opinion specials in 1 v 1's and works well as both junlger and solo top. This build gives him ALOT of durability in team fights and in laning phase, or just during jungling phase. It also gives him the DPS he needs to be a real threat in team fights. In laning phase having a friendly warwick fiddlesticks or amumu as jungler can make for very good results during the laning phase early or middle game. His ability to back door is also good as his sheild blocks turret bullets. I suggest using his ult to get into team fights or escape if neccesary. dont rely on it for kills cause is obvious where it hits. Try to do as much poking damage as you possibly can early game, use your spear shot wisley cause u dont have much mana at begining of the game. during jungling always start at blue with him and make ur way down to the two golems, get red right after wraiths and then gank if possible. Make your openents fear pantheon by using this build. Last use this move combo use ur stun then ur heartseekers, after that use spear shot and chase down if needed. Play him smart and your team will love you:)

Pros
Strong laner
Good farmer
bruiser
solid throughout game
high damage with good defenses
Great backdoor
Cons
easy to counter with some champions
low mana
many different builds
not the best jungler out there.
NOTE: pantheon is a great counter to most mid champions. if needed you can definatly take mid with this build. I use this build myself and its been awhile since ive gone negative using pantheon:) so enjoy the build RATE AND COMMENT:)
