For the 99% of us that can't find a SMK I feel the best alternative you can have is the Rhen'Ho Flayer with Addling Toads. I finally got my full Zuni set and wanted to make a new video showing how easy it is to cruise through T5 using the Flayer.
My dps isn't that great for this as I lose a couple hundred thousand DPS to wear this gear due to crappy rolls (738K profile dps currently) I hope to find a better flayer as i have seen others with 300 more dps on theirs.
The Crowd Control capability of the frogs and Piranhado combined is priceless. Even playing solo you so I am taking almost no damage from attacks as everything is occupied with confusion, or dealing with my pets. When i try firebats I am under attack so much I have to move and dodge and try to recast FB and i end up running OOM trying to re-position and cast. With frogs you can constantly be moving and casting to continuously be streaming frogs and producing sycopants.
My AS is also very low now i think 1.8 for this. Everyone is obsessed with firebats and getting out as many fetishes as possible but i think this works just fine. I know once i counted and i had 21 fetishes out at one time. That is more than enough to get in each others way and create too much congestion as it is. I normally do not play solo, I typically just do T5/6 rifts with 4 players. Everyone in my party takes so much less damage with this build it is an invaluable asset.
I hope to get some replacement gear and get my AS back up to 2.0 where i had it.
This setup is so underrated and I am just suggesting that everyone who finds a Flayer should give it a shot and you will be pleasantly surprised!
