Everybody can see how simple it is - but there is a big problem for you guys, for ppl that are going to test it out.
YOU WILL DIE ALOT AT THE BEGINING - yes its true you will be insta killed by charges - or just get eaten by flying frongs.
So what should we do there? Well, If you are begginer with this build you should always make a quick stop when you encounter the flying frogs and kill them asap (or kill most of them) because they are faster then you (even with 24 ms) and will rip your soul prety fast unless you have 800k EHP +.
Try to avoid monster mega pull at first few games, because you will need to get used to it - you need to use little macro to keep your spirit walk 100% up for avoiding charges.
about chargers.. you cant do anything about it. Well actualy you can - you can spirit walk it or simple Horify it to not get insta gibbed. With my 400 ehp I get to 10% and then the rest mobs kills me , because it basicaly knock you and interupts your bats.
Now there are two ways how to play act 1.
Just go field of misery - clear it up (avoid keywarden) and then restart the map
Festering - clear every rare /event
Field of miser -> Weeping hollow
If youre gear is not super strong 400ehp and about 160k dps unbuff. you should practice this on mp8. Its lot of safer and faster thou. For this build youll need a little bit of practice to master it.
