I completed the Dawnguard on the Vampire side with my Assassin Character. As a result, I also chose to make a trip to the Dawnguard's base, and go **** with their days.
Fast forward a few months, I see on youtube that you can get upgraded crossbows if you follow some side questlines from some girl at the base. Naturally, she is dead now. Arrow right between the eyes appears to be the cause of death.
So, is there any way else of attaining these quests? or the crossbows? They would make an ever so lovely addition to my collection.
The only way to get the other crossbows is to join the Dawnguard.
Same with the Sunfire/Vampire's Bane/Stendarr's Aura spells.
And the Dawngaurd Rune weapons.
And some other things.
Weapons are Dawnguard only but spells can be purchased using Vampire Seduction.
Or anything that pacifies them. You either need mass-pacification spells or exceptional stealth since as soon as one of the Dawnguard see you , they will all attack you which can make singling out the right people to charm somewhat difficult.
