List 1 Best
- Zahra (Morituri)
- Serequet (Morituri)
- Anyone (Morituri)
at this point, in any arena with pits, Zahra is really top-tier. Her ability to engage at 5 inches AND push in any direction really sets her apart from everyone else in the game. Especially with her Reposition, she's able to power attack every other turn, or, attack twice every other turn, and deny the same to her foes, because she remains engaging, but not engaged.
Ludus Benefits are not even required for this combo. Neither is Serequet, but he just adds to her mobility and resilience, as well as adding some real hitting power in case of a fluke that lands her engaged (as well as offering immunity to opportunity attacks)
List 1 Best
- Sven (Blood Brothers)
- Vargr (Blood Brothers)
- Hroka (Blood Brothers)
- Caho-Ta (Blood Brothers)
- Frigge (Blood Brothers)
This one gains it's power from a few different things, as Basuh and Duneedon have pointed out, the Blood Brothers Ludus benefit is very, very strong. This is coupled with Sven's swift ability, and Hroka/Caho-Ta's every other turn of four attacks (though Caho-Ta's attacks are not huge, they do add up, and as an opponent only gets one reaction per turn, having to decide when it comes to four seperate attacks can be a staggering choice to make.) The paid benefit of two reactions per turn is also particularly brutal, given that you can essentially make an attack with Vargr during a move reaction, and a counter attack with the individual being attacked, and still fall within the limits of having to do different reactions.
I'm honestly having a hard time coming up with "worst" lists, as for the most part, cohorts don't seem to be underpowered, it's just a few seem rather strong.
