Just unlocked Skaarf after Triple Glory Weekend and I wonder why I never got him earlier. He is great in my opinion. I switched to him after playing Adagio/Vox and really enjoy his difficulty. Sure shot precision makes him a challenge that I am happy to tackle. This build is great. Thanks

Well in this patch the damage was moved to his abilities and the ult damage was weakened , so sometimes it is better to go A & B route , plus if your opponents know what they are doing when they drop a little bit before half they pop a fountain and then another one after a short period making the damage from the ult useless and you will find yourself in a situation "ult didn't kill enemies , abilities do damage but not enough (since goop isn't overdriven) you will start losing that teamfight" , and I am very glad you liked the guide , I will probably update it when 1.6 arrive if changes happened to skaarf

This build is great, but just wondering why you do not overdrive the ultimate?

You are welcome , glad that my guide was of benefits :)
Skaarf is an awesome champ he will be even better in the next patch so stay tuned

Thanks for great explanation, I love skaarf
