Ravenlore vs +6 magic vs +5 rare vs shako

The +6 can have 3 sockets possibly (in 1.07 larzuk, where I would farm it)

rare, i have a +2 ele/+3 fissure no sox helmet, don't think it will cut it. (rest stats are not good)

what's the best in terms of killspeed+mf, survivability?

all holes probably filled with PTs

Which area do you suggest to play him?
go allin on fissure?

Merc will carry infinity

Shako. Your damage will be fine against non fire immune monsters and you won't really be breaking fire immunes.

There aren't many areas you can play it. Andi, Meph, Mausolum/Crpyt, Ancient Tunnels and The Pit. Skip any fire immune packs.
