Helbore Demoshooter
 Veteran Build - Warhammer 40k: Darktide 

Helbore Demoman

1.   This build is quite simple, we are using krak grenades and our trusty helbore to destroy specials, armour and Bulwarks that are useless against this build.
2.   Helbore is used for ranged specialists, Brushers, all Ragers, Maulers and the occasional Bulwark.  Also if a mutant is coming after you, use the helbore's special attack the bayonet, it will kill mutants in no time.
3.   Krak grenades are used for most of the Bulwarks and the  massive chunk of armour coming your way and need to retreat no, use the krak grenades and shout for the effect of being a mobile turret and killing everything that surrounds you.
4.   Other sources of horde clearing and providing support is to use your shout and shovel to waylay into hordes for some quick easy kills and to make sure you pull out your helbore after that for some sniping.  
5.   You can mess around the perks for the helbore and it's not necessary to have flak or weak spot damage,  but flak is important against maulers and ranged weak spot damage is universal.  To add on more perks you might want,  Carapace, Unyielding is ok but we use kraks mostly, and Maniacs are a good one.
6.   The shovel should be as is, weak spot damage is what you want and skullcrusher,  the other perk and blessing could be whatever as long as you have weak spot damage and skullcrusher.
7.   Last tad bit of information is that you can get rid of the extra grenade and opening salvo, the 2 diverging paths on the Voice of Command, for Rending Strikes, Superiority Complex and  Stamina Regen boost.  Keep the Critical Chance on the right the small node.  
8. That is it, the build could be used with a MK III Helbore Lasgun as well,  but it does lack the proper bayonet as well, You can swap out a helbore for a infantry Lasgun as they would perform the same function, just use kraks for Crusher and Bulwarks.
9. Let me know what you think of the build as it does have many options and it's quite versatile.
