What you need:
- A Barbarian with at least 1 point in all skills of the Masteries tree, Battle Command, Battle Orders, and Shout.
- Proper stats to equip the buff items.
- Items to add states: Dream, Dragon, Infinity, Treachery, Rain, Demon Limb, et cetera.
Basic description of the 'sploit:
An entity that exceeds 18 (or 19 - something like that) states causes the server to send a packet (0xAA) to the clients in which the state info is too long with no terminator. This results in a deadlocked client, and the victim must end the Diablo II process before they are disconnected from Battle.net (there will be a short delay thereafter as well). This can lead to literal EZPKs.
What to do:
- Get 13 states from Masteries, BO, BC, and Shout.
- Get 6 more states from buff items.
- Get within 3-4 screens of your victim(s). (-edit;clarification- You must be off their screen beforehand and *then* get within their proximity.)
- Watch them sit there for a minute (Optional if possible: PK them) and then they will eventually drop.
