One stabbo from the sword and the Blue Boy is dust.
Seriously, they try to downplay it by writing stuff like "Abaddon’s unholy wargear may just give him the edge" but it's not just some random 'unholy' gear or relic or whatever. It's pretty much THE sword beside the Emperors/Guillimans sword and the Talon has quite a history too and if we know anything then it's that superstition and history affect reality quite dramatically in 40k.
Just according to fluff and novels, Drach'nyen and the Talon should pretty much instagib anything they hit.
The End of Empires scared the Emperor himself and it probably has a better shot of killing him than anything else in the galaxy.
We don't need to talk about the Talon, a weapon that mortally wounded the Emperor, killed a top tier Primarch and wasted a perfect physical clone of Horus with one mean stab.
I know they can't make his weapons too powerful for balance reasons, but I hope they redesigned Drach'nyen and use something more like the 30k stats for the Talon of Horus.
Always liked Drach'nyen in 3rd Edition(?), where you only got one strike, but when it landed you just kill whatever you hit. At least make it deal a ton of mortal wounds.
I still remain very exited about this release. It's not like I've waited close to 20 years for this happening
