Did 20 Steel Cyclones for Perdu and Lyft each. Swapped out earring so str would be same. With 3 in party the damage was pretty much the same: 906 (Lyft) to 913 (Perdu)
Maybe the tp bonus triggers with full pty only or it scales with member numbers and wasnt noticable with 3?
Edit: I know small sample but people had to go.
