The most reliable Bloodthirster roster possible unless you play without any Bloodletters. 2 RR's will make things very tough, so make sure when you do hit opponents players you make them count, with 3 dice blocks every time. Also make sure you have players in a position for your Thirster and Letters to attack should they fail Bloodlust.

Similar to the standard Vampire roster though you start with one less Re-roll. 3 Re-rolls is about all this roster can manage though just make sure you have Cultists in positions for your Letters to attack, you don't want to be attacking your own Letters too much. Also remember sometimes it may be advantageous to let your Bloodletter warp in to the crowd and slaughter them rather than let them attack their own players.
