Editing Horus (section)

==Horus VS other Primarchs, Horus Heresy 1.0==
<div class="toccolours mw-collapsible mw-collapsed" style="100%">
Horus wins against any other Primarch except Leman Russ and super-charged Magnus. That's it. He beats ALMOST any other opponent he gets pitted against, although it'll take a while with Vulkan.
<div class="mw-collapsible-content">
No seriously, what did you expect? With WS 8, 6 Attacks with a S7 AP2 lightning claw that cripples whoever survives his onslaught or a MC S10 Thunder Hammer and 2+/3++ he can destroy almost any other Primarch relatively safely. He's clearly built to be the hardest dude around and his gear is borderline unfair. Disabling Strike is just disgusting and it's directly intended to make sure he stays the top dog no matter how [[Angron|angry]], [[Fulgrim|pretty]] or [[Perturabo|well]] [[Ferrus Manus|equipped]] anyone else is... [[Sanguinius|so long as he doesn't piss off the Angel]]. Ouch, that Talon really hurts. So, yeah, almost no one can actually fight 1 on 1 with the Warmaster, barring some incredibly lucky rolls.

'''These are the old numbers on Leman Russ pre-FAQ:'''
<div class="mw-collapsible-content">
*Horus vs. Leman Russ
**Horus, Round 1: Hits 2 times, wounds 1.777 times with his Claw, 0.888 wounds after saves, and IWND brings it down 0.555
**Horus Round 2 and on: Hits 1 time, wounds 0.888 times with his Claw, 0.444 after saves and IWND brings it down to 0.111
**Leman Russ, full Wounds + charge/Counter-Attack (Balenight): hits 4.667 times, wounds 3.502, 1.167 wounds after saves and IWND brings it down to 0.834 at the start of the next turn.
**Leman Russ, full Wounds + charge/Counter-Attack (Helwinter): hits 4.861 times, wounds 4.051 times, 1.350 wounds after saves and IWND brings it down to 1.017 at the start of the next turn.
**Leman Russ, full Wounds (Balenight): hits 4 times, wounds 3 times, 1 wound after saves and IWND brings it down to 0.667
**Leman Russ, full Wounds (Helwinter): hits 4.190 times, wounds 3.492, 1.164 wounds after saves and IWND brings it down to 0.831 at the start of the next turn.
**Sever Life: Being a pain in the ass to calculate, Sever Life will go off most of the time against Horus, but for the purposes of this mathhammer Sever Life's chance to not go off will be included in its average Wounds roll:
***Every time Leman Russ Attacks Horus (as he'll always manage to Wound him and it doesn't say it's triggered via unsaved Wounds) Horus takes an additional 1.091 Wounds, only 0.364 of which will make it through Horus' save.
**Keeping Sever Life in mind and the fact that Leman Russ can split his attacks, the ideal way to split them (for round one and two anyway) would be: 2 Attacks with Balenight, 4/5 Attacks with Helfrost. Here's what that looks like:
***Leman Russ, full Wounds + charge/Counter-Attack: hits 4.851 times (1.333 times with Balenight, 3.518 times with Helwinter), wounds 5.023 times (1 time with Balenight, 2.932 times with Helwinter, 1.091 times with Sever Life), 1.674 wounds after saves and IWND brings it down to 1.341 wounds at the start of the next turn.
***Leman Russ, full Wounds: hits 4.177 times (1.333 times with Balenight, 2.844 times with Helwinter), wounds 4.461 times (1 time with Balenight, 2.370 times with Helwinter, 1.091 times with Sever Life), 1.487 wounds after saves and IWND brings it down to 1.154 wounds at the start of the next turn.
Leman's negative to hit modifier is brutal, basically negating Horus' ability to do any damage, while Leman is still pounding him over the head. As stated, this includes Sever Life and Breaker of Shields, Bringer of Ruin. The theoretical breakdown of the match would be:
*Round 1:
** Leman Russ, 6 Wounds, WS9, S6 + charge/Counter-Attack (2 attacks on Balenight, 5 attacks on Helwinter): hits 4.851 times (1.333 times with Balenight, 3.518 times with Helwinter), wounds 5.023 times (1 time with Balenight, 2.932 times with Helwinter, 1.091 times with Sever Life), 1.674 wounds after saves.
** Horus, 4.326 Wounds: Hits 2 times, wounds 1.777 times with his Claw, 0.888 wounds after saves.
*Round 2:
** Leman Russ, 5.112 Wounds, WS9, S6 (2 attacks on Balenight, 4 attacks on Helwinter): hits 4.177 times (1.333 times with Balenight, 2.844 times with Helwinter), wounds 4.461 times (1 time with Balenight, 2.370 times with Helwinter, 1.091 times with Sever Life), 1.487 wounds after saves.
** Horus, 2.839 Wounds: Hits 1 time, wounds 0.888 times with his Claw, 0.444 wounds after saves.
*Round 3:
** Leman Russ, 5.001 Wounds (IWND puts him slightly above 5, but it can't regenerate his damaged characteristics), WS8, S5 (3 attacks on Balenight, 3 attacks on Helwinter): hits 3.188 times (1.5 times with Balenight, 1.688 times with Helwinter), wounds 3.498 times (1 time with Balenight, 1.407 times with Helwinter, 1.091 times with Sever Life), 1.166 wounds after saves.
** Horus, 2.006 Wounds (IWND): Hits 1 time, wounds 0.888 times with his Claw, 0.444 wounds after saves.
*Round 4:
** Leman Russ, 4.557 Wounds, WS8, S5 (3 attacks on Balenight, 3 attacks on Helwinter): hits 3.188 times (1.5 times with Balenight, 1.688 times with Helwinter), wounds 3.498 times (1 time with Balenight, 1.407 times with Helwinter, 1.091 times with Sever Life), 1.166 wounds after saves.
** Horus, 0.84 Wounds: Hits 1 time, wounds 0.888 times with his Claw, 0.444 wounds after saves.
*Round 5:
** Leman Russ, 4.446 Wounds (IWND), WS7, S4 (The Talon of Horus technically causes another unsaved wound here) (all attacks on Helwinter): hits 3.214 times, wounds 1.607 times, 0.536 wounds after saves.
** Horus, 0.637 Wounds (IWND): Hits 2 time, wounds 1.778 times with his Claw, 0.888 wounds after saves.
*Round 6:
** Leman Russ, 3.558 Wounds, WS6, S3 (all attacks on Helwinter): hits 3.214 times, wounds 1.071 times, 0.357 wounds after saves.
** Horus, 0.28 Wounds: Hits 1 time, wounds 0.888 times with his Claw, 0.444 wounds after saves.
*Round 7:
** Leman Russ, 2.67 Wounds, WS6, S3 (all attacks on Helwinter): hits 3.214 times, wounds 1.071 times, 0.357 wounds after saves.
** Horus is dead before IWND kicks in for him and so cannot strike back.
Mathematically, if Russ takes full advantage of Breaker of Shields, Bringer of Ruin then Horus loses the fight in 7 rounds (4 game turns!) while Russ still has 2.67 Wounds left. Whoah.
*Do note that IWND messes up the math a little at face value for Talon of Horus. Since Russ does not gain characteristics back that he lost because of Severing Strike, he'll appear to have fewer unsaved Wounds than he actually does.

The above was based on Russ' armour before it got nerfed, which before would make -2 to hits against by round two. Now it is only -1 for the entire battle.

'''Recalculations from Reddit by u/Fromageopain, showing Horus' win:'''
<div class="mw-collapsible-content">
*Round 1 (Russ's turn, 7 attacks from charge. If turns are swapped, still 7 from Counter-Attack, but Horus makes IWND first)
**Russ [6 Wounds, WS9, S6, 2 attacks with Balenight, 5 attacks with Helwinter]
***Hits 1.333 times with Balenight and 3.912 times with Helwinter, wounds 1 time with Balenight, 3.2601 times with Helwinter and add 1.091 for Sever Life. That leads to 1.7833 wounds after saves.

***Hits 2 times, wound 1.778 times, 0.889 wounds after saves and 0.444 after IWND.
*Round 2 (Horus' turn)
**Russ [5.444 Wounds, WS9, S6, 2 Balenight 4 Helwinter]
***Hits 1.333 times with Balenight and 3.201 times with Helwinter, wounds 1 time with Balenight, 2.668 times with Helwinter and add 1.091 for Sever Life. That leads to 1.586 wounds after saves and 1.253 after IWND
**Horus [2.969 Wounds, 6 Talon]
***Hits 2 time, wounds 1.778 times, 0.889 wounds after saves.
*Round 3 (Russ' turn)
**Russ [4.555 Wounds, WS8, S5, 4 Balenight 2 Helwinter]
***Hits 1.5 times with Balenight and 1.375 times with Helwinter, wounds 1.111 times with Balenight and 1.407 times with Helwinter and add 1.091 for Sever Life. That leads to 1.203 wounds after saves.
**Horus [1.766 Wounds, 6 Talon]
***Hits 2 times, wound 1.778 times, 0.889 wounds after saves and 0.444 after IWND.
*Round 4 (Horus' Turn)
**Russ [4.111 Wounds, WS7, S4 (he is over 4 wounds thanks to IWND, but lost his characteristics since the talon wounded 4 times), 6 Balenight]
***Hits 3 times , wounds 0.917 times and add 1.091 for Sever Life (let's be kind), 0.669 wounds after saves and 0.335 after IWND.
**Horus [1.430 Wounds, 5 Talon 1 Worldbreaker]
***Hits 2.5 times with Talon and 0.75 times with Worldbreaker. wounds 2.222 and 0.625 times. That leads to 1.111 and 0.313 wounds after saves.
*Round 5: (Russ's turn)
**Russ [2.687 Wounds, WS6, S3, 6 Balenight]
***Hits 3 times , wounds 0.917 times, add 1.091 with Sever Life (let's be kind again), 0.669 wounds after saves.
**Horus, [0.761 Wounds, 5 Talon 1 Worldbreaker]
***Hits 2.5 time with Talon and 0.75 times with Worldbreaker, wounds 2.222 and 0.625 times. That leads to 1.111 and 0.313 wounds after saves. IWND brings this down to 1.09 wounds
*Round 6: (Horus' Turn)
**Russ [1.596 Wounds (IWND), WS5, S2, 6 attacks on Helwinter (Str2 cannot hurt T6)]
***Hits 3 times , wounds 0.582 times, 0.194 wounds after saves (not enough to actually kill Horus) and IWND will mean that Horus will actually heal more than Leman inflicts, resulting Horus gaining 0.139 wounds at the end of the turn
**Horus [0.900 Wounds, 5 Talon 1 Worldbreaker]
***Hits 2.5 time with Talon and 0.75 times with Worldbreaker, wounds 2.222 and 0.625 times. That leads to 1.111 and 0.313 wounds after saves.
*Round 7: (Russ's turn)
**Russ [0.172 Wounds, WS4, S1, all attacks on Helwinter]
***Hits 3 times , wounds 0.582 times, 0.194 wounds after saves.
**Horus [0.761 Wounds, gain +d3 attacks] and finish Leman...

Keep in mind that these results are made considering that Sever Life will apply regardless of Horus successfully saving the wounds inflicted by Balenight which is greatly benefiting Russ and is probably not the way the rule is supposed to work. On a side note, if Sever Life only triggers when Horus suffers an unsaved wound from Balenight, then the fight is way more one sided in Horus' favor because Leman would have to make more attacks using the sword in order to trigger Sever Life, losing damage since the axe hits harder than the sword.

Take in mind however these above scenerios do not take into account Russ's secret weapon basically designed to counter challenge shenanigans. And even barring that Leman Russ puts up easily the closet fight against Horus on any given day regardless.

The Wolf-kings secret weapon being: Wolves... yeah. Russ can choose to have both his dogs accompany him, both of which are characters. Thanks to how wound allocation and challenges work, Russ can force Horus to engage with the dogs instead of him for 2 whole rounds, making Horus use Worldbreaker to ID the dogs, since if he uses the Talon it'll take 3 wounds total to kill one dog and he can tank the full Worldbreaker on himself to stop the other dog from dying too fast, which prevents his stats from dropping early. As even one extra round of no stat dropping changes everything and by the time his stats even start to drop there is a high probability Horus will be on his last couple wounds if not already dead when the attacks from the wolves are added in to augment Leman Russ. Emperor's Executioner indeed.

Thanks to HH6: Retribution, the Mechanicum has its primarch-like character. [[Anacharis Scoria]], lord of Xana and the first of the Dark Mechanicum used to be able to easily kill Horus thanks to a 3+ Invuln, Feel No Pain, and a weapon that wounds automatically and causes D3 wounds at AP2 per hit (making Horus' talon worthless). This allowed him to kill Horus in 5 rounds, whereas Horus needed 6 to kill him in return. He also got nerfed in the same FAQ that nerfed Russ, so now Horus kills him too.
