Gotta admit, or did I miss it

[Dani]

I have some of the nicest (A Legit Piece of Poison), most legit stuff out there because I work for it

Hmm.

Small Charm

Prefix Pestilent 175 poison dam in 6 seconds lvl 88
Suffix Anthrax 50 poison dam in 6 seconds lvl 44

Now yours has a 10 second timer, and I don't pretend to know how exactly items work. So.
Question1: how is that charm possible?
Question2: Why do dupers limit themselves to 290 poison damage in a small charm.

Frankly I've never seen a legit SC with more than 121 poison.
