Hi all,Im Verglia,diamond 3 curently on eune,maining panth for whole season 2 and 3 ...I won a tons of rivens,jaxs,and others just buy playing agressivly and knowing my champs limits and cd in my head.This is my first build on mobafire for him and i hope it helps you mantheons all around :) hope you find it usefull.Good luck summoners !

+OP early game
+Great ulty(hard to master)
+Man mode
+Little counters

-Very hard to master
-Easy for gank
-Needs kills to be strong
-Needs balls(and team) to use his full potential

My advice is :
1)dont miss last hits,but harras always(thats why you use flask for)
2)ALWAYS,ALWAYS buy 2 wards (even if it means you dont have for item)
3)ALWAYS ban shen
4)ALWAYS ban zyra(i cannot explain why,but trust me)
5)Dont be afraid to go all in
6)ALWAYS ALWAYS gank bot lane for easy kills with ult and let your jungler def top for you
7)If mid is losing ,jump and help mid instead

Early on,you must only look for fb and farm.On lvl 6 you jump on bot or mid,while your jungler defends your lane.Mid game you should focus on helping team with your jumps behind enemy lines,make kill or 2 on their carries and prepare to die(hope your team can carry on your sacrifice).Late game is a little weak,but still you can manage to separate their tanks from their adc,apc...They cannot ignore you,so they must kill you,and you will take 1 or 2 of them 100% if you play right.The point is,if you win early on,everything will be much easier,exp with panth.

Only flash and ignite,in s4,maybe barrier is viable,im not sure yet,but its only replacement 100%.

Main counters are : shen(he can follow you with stand united,and he has good armor and sustain,panth hates sustain champs),Zyra(big burst,big cc,good poke),Rumble can be hard win too,Nasus can dominate you after 7-8 lvl(but to be honest,he can dominate anyone after 15 min game),Elise is strong too,so ban her,And maybe malphite,but no one plays him anyomore ,so...Verdict : Ban shen,zyra,rubmle,and you are good to go :)
