Fungi covered great staff and sham
 

Is the(post nerf) staff a decent buy on a sham for leveling? Does fungal regrowth stack with our regen line?

It is a snare/regrowth spell. So it gets rid of sow and it does not stack with other regen spells. I leveled my shaman up with a fungi and the staff until I actually got the spell. It only lasts 5 minutes from what I remember and switching between that and my epic was annoying.

Does it stack with the fungi? I was under the impression it diddnt, does that mean its a 30+ hp a tic regen? and is there a level restriction on its use?

It stacks, its a clicky buff. Doesn't stack with buffs like regen.
Clickable at lvl35.

Good
 

I used it on my shaman from 35-52. Once I got to 45 and using JBB, I would just slow mobs to pull and nuke them down. I hardly had any hp/mana issues. It was worth the cost and was able to resell at no loss.

That strat sounds so fun.
