i have over 11 dota 2 invites + many very rare dota 2 items im willing to give it all for the dishonored whoever is interested just tell it

You can post this in the Steam Deals thread. That's usually where people bring up trade stuff.

Also, I'm pretty sure that DOTA 2 is an open beta, so I'm not sure how much the invites are worth.

invites are worth a few pennies.
