Ultramarines into D&D 5.5e
I want to try to implement all of the Primarch space marine factions (and the Carcharadons) into D&D 5.5e. I got this idea from the youtuber, Tulok the Barbarian. I figured I’d start with Ultramarines since they are the "Basic" and well-rounded faction, being good at everything, but not great, so they should be a good starting mold. I only currently play Tyranids and Thousand sons, so most of my knowledge came from their wikipedia page. So, I was wondering if you guys had some key characteristics I missed or Ideas I should cover in my build that you would expect from Ultramarines. I’m trying to go for more of a lore feel than a tabletop feel and for more of the general Ultramarine, so like no Apothecary, Techmarine, or Librarian.
My current ideas are for them to be human with the majority of some kind of fighter. I’m avoiding spellcasting class as much as possible. I’ve thought about going into at least 3 levels of artificer for the armorer subclass and infusions being their access to most of the armory. One I’m the least sure about would be like a level dip into Ranger to get Hunter’s mark. I’m giving the character 50 gold per level when they level up to buy new and more fitting equipment, i.e. buying heavy armor later down the line. I am also using standard array for the stats.
I’m open to suggestions. I’ll post back in like a week or so once I finalized my build to show it off and maybe get some final suggestions.
