the tempestus scions are the guard's elite, sent on surgical missions where mission importance is highest. this build is all about utilising the kantrael lasgun to dominate the ranged play. most people are surprised at how much damage is taken from shooters, so when using this build expect people to note on how "clean" or "easy" the game was, and thats because you have been shooting like a maniac the whole time to clear the way for your precious ogryns and zealots.
strategy: you have enough ammo to use the kantrael lasgun for the whole game if you want. headshots are your bread and butter so accuracy will entirely determine dps, toughness and ammo sustain here. if you do it right you wont need to pick up a single bit of ammo. you will be aiming for shooters, big and small. if it has a gun its your job to kill it.
important: a lot of people are scared of moving with marksman's focus but dont worry yourself with that. move about as much as you like while shooting. one headshot kill means stacks are sustained for 6 seconds, one heashot hit and you keep them for 3. it is hard to lose stacks until you run out of heads to shoot.
breakpoints: you will always be one shotting small shooters, but you need about 5 stacks of marksman's focus, or executioners stance active to one shot gunners. dont worry though these are extremely easy to get to so you will be headshot killing them 90% of the time. it will take about 3/6 headshots depending on stacks to kill a reaper but they are easy targets so its no big deal.
weaknesses: bosses and crushers. use krak grenades on both, but if you are playing on auric or maelstrom you simply wont have enough nades to kill all of them. if your team is not killing bosses or crushers you are in big trouble. the folded shovel can headshot the crushers down with relative ease but its not nice to pull off.
plague ogryns can be locked in animations with its head in one place if you hug it and dodge its attacks, so you can get some nice headshot damage with the lasgun. the beast of nurgle will go down to a few dozen well placed shots in its yellow spot, and the spawn is hand made to kill you so dodge and run.
interchangeables: heavy swords and duelling swords are good options, all kinds of axes too. however, all alternatives (except for the tax and duelling sword) lack the mobility to get space to shoot, so its up to you.
the tempestus scion build has a much different target priority to most other builds so it may feel weird, but if you can pull it off your squad will have a much easier run and it will be all thanks to you. may your aim be true and righteous in the emperors name!
