1. Does it do one inv in one cast?

2. Is it 83 exp per cast? or is it 83 exp per amulet?

3. Do I use one set of runes per cast? or per amulet?

 

The last two questions kind of depend on the first one, so I'm a little confused.

1 cast = 1 amulet

if you have 25 amulets in your inventory, then it's 25 sets of runes and 25 casts

Quickly strings all amulets in your inventory, without needing any wool. One set of runes is used for each stringing. (Also gives 4 crafting experience per amulet).

 

1. It strings them all

2. It's per cast, but it continuously casts it until all your amulets are strung

3. One set per amulet.

 

That's IIRC.

As previuosly said... simply: You click the spell once, and it strings your ful inventory, however for each amulet it uses the runes for one cast and gives you the xp for 1 cast
