Who do you think is the best special character currently in the game? I will attempt to throw together a list by army. If I feel that a codex does not have a good special character then I'll just put NA beside that army. So here we go!
01) Black Templars:
Marshal Helbrandt, Chaplain Grimaldus
02) Blood Angels:
Astorath, Dante, Mephiston, Sanguinor
I know most will pick either Mephiston or Sanguinor but based upon my own playtesting I have to pick Dante as he is the greatest force multiplier in my opinion. Note that I would rather take a character that is a force multiplier over say a scary close combat monster.
03) Chaos Daemons:
Blue Scribes, The Changeling, Fateweaver, The Masque, Skulltaker
I think the Fateweaver is the top choice here. The others I listed are popular as well so I included them as well.
04) Chaos Space Marines:
I'd like to include the winged lash prince but it's obviously not a special character.
05) Dark Angels:
I was tempted to go with NA but there are those who still love their Deathwing & Ravenwing. I respect that too. I haven't seen anyone taking Azrael so I didn't include him.
06) Dark Eldar:
07) Daemon Hunters:
Eldrad, Maugan Ra
Eldrad is one of my top choices for best overall.
09) Imperial Guard:
Al Raheem, Creed, Sly Marbo
While I rarely ever see anyone field Creed he is pretty solid for blob IG. Marbo is obviously the most popular by far.
The Deceiver, Nightbringer
The Deceiver is another one of my top choices. Just like Eldrad his ability to redeploy is often overlooked but very powerful.
Ghazkul Mad Thrakka, Snikrot
Ghaz is another top pick for me!
12) Sisters of Battle:
13) Space Marines:
The Khan, Captain Lysander, Vulkan
Vulkan is another top pick for the best special character & extremely popular amongst those who love their power armor.
14) Space Wolves:
He has to compete with the generic Wolf Lord mounted on a Thunderwolf but Logan is definitely a very strong force multiplier and a staple to many Space Wolf armies.
Deathleaper, The Doom of Malanti, Swarmlord
If I missed any let me know!
