Any advise with dealing with the Great Unclean One? I have been facing lists with 2 of them, and as support they use rotbringers blightkings. I tried almost anything to bring them down, but it`s like fighting jello, they just soak up wound and then heal them back up again. Also the magic they bring is very nasty. maybe someone has an tactic, i`m at an loss atm.
My only luck was just straight up ignoring it and trying to score objectives. After turn 3 I just stopped wasting my attacks on him. Screen with skinks, run them away if you get the chance. If they die just try to summon more to occupy him. I dont know about all nurgle players but the guy I was playing was not happy about having to charge the GUO into skinks
Shadowstrike could work. Or concentrated fire by multiple Bastiladons, they do extra damage against Chaos Demons.
This is one of the best ways to deal with tough targets for seraphon, since damage output of our army is not high. If you play missions, where infantry scores objectives, just grab them with skinks and re-summon them, as they die. This won't work with scenarios like Duality of Death or Places of Arcane Power. Shadowstrike with 6 rippers, 4 razordons, bastiladons in thunderquake battalion and, maybe, oldblood on carno with his command ability used 3-4 times are our best units to deal damage. But you probably still need some good rolls to kill such a resilient model.
If you just want to annoy them bury them in skinks. Other than that to kill them you can bring what's already mentioned. however two potential units have been left out. - Shadowstrike with Chameleons, you're going to bring the shadowstrike anyway, bring some chameleon skinks. 32 of em in a shadowstrike host will kill a great unclean outright. They'l provide some much needed firesupport for your rippers to Ensure the kill. - A sunclaw host, but not necesarily at maximum strength, alongside some big scary stuff for distractions. Even without the horde bonusses (and without alpha's) you only need 40 saurus in a sunclaw host to kill the great unclean one. Basicly, a minimum sized sunclaw starhost of 3 units of 10 alongside their sunblood stand a decent chance of killing an unclean one in a single turn. Now bring 3 units of 20 and they'l shred the unclean one to bits. And since everyone is used to saurus warriors being well, garbage, outside of massive, buffed up, hordes, chances are your opponent will likely not even bother harrasing a 20 man unit of saurus and instead focus on taking down your big shiny dinosaur whom you keep on saying is amazing and is going to nom his great unclean one. Admittadly, he's only going to be caught by surprise by this once.. Though even if he knows it's coming it's a very cheap way of distracting him from other potential threats. A 10 man squad of saurus warriors in a sunclaw host puts out a potential of 41! wounds against a great unclean one on their own. That's a rather powerfull threat, scary enough to get him to make mistakes.
32 of them is a but too expensive, plus you take them in group of 5s so taking 32 is kinda pointless imho
I'm running a Sunclaw Starhost as my first battalion and one of the dudes teaching me the game is a Nurgle player with a GUO he's been itching to break out against me. I'll try this theory out sometime soon and let ya'll know how it works out.
Tbh, I think bonusses like that although thematicly fun are terrible for the balance of the game. The unit always ends up being too weak whenever the bonus can't be triggered.
If they are bringing 2 great unclean ones, you could bring a bunch of salamanders. Two units of 4 would likely kill one in the shooting phase. Thats 320 pointa of sallys vs 340 of an unclean one.
That does require getting your sallamanders safely in range though. And without handlers they won't have the range to be teleported there. If he trows a spell or two their way you're liable to lose a salamander or two before ever getting in range. Also 8 salamanders only barely manage to kill a great unclean one on average (about 15.1 wounds on average against a great unclean one). All in all seems like one of the riskier options.
