Found a bunch of 100s and a 451 large charm. Any cool builds for this?

Poison barb.

Yes many.

Barb can use dual death web, trangs and a 20fcr/15ias/15@/10psn-10psn helm with widowmaker.
Thats a huge psn damage.

Hammerdin with widowmaker. Trang ouls etc. any hybrid.

Bowa with theese scs.

Psn dagger necro with bow and lr, or any necro.

Actually everyone can use this.

But venom build is bad with those scs. Venom destroys the damage of the scs.

Also good on chanter/hs sorcs.

Pala is good due to Fana widow.
Necro is good due to lr.
Ama is good due to base bow skills.
Barb is good due to dual wep switch and bo as base skill.

Thanks for the suggestions. Definitely going to play around with this
