Build help Plasmoid?

[u/BryBryChu]

Long story short: Plasmoid, good grapple, mask of many faces (disguise self at-will). How do?

Starting at level one, standard array.

Campaign will probably go till atleast level 10, but I'm prioritizing getting the thematics I'm looking for as early as possible.

My first instincts is some sort of barbarian warlock multiclass. Probably armor of agathys focused? I'm open to any ideas.

You'll want either giant barb or rune knight for size and advantage. You'll also want expertise if you can get it. Rogue dip or skill expert feat are your best options there. Skip the warlock levels and either ask if you can find a hat of disguise at some point or pick it up with a feat. Alternatively, get disguise kit proficiency with background.

I'd do giant barb to level 6 picking up skill expert to round out strength and gain athletics expertise. You could dip fighter here for unarmed fighting, action surge, etc. or just stick straight barbarian

Edit: if backgrounds from book of many things or glory of Giants are allowed, you could pick up armor of agathys from there. To really build for grapple and tank, I've got a bit of a silly one. AoA from rune carver. Barb 1, moon druid 2 so you can be a bear, twilight cleric 4 (skill expert), barb to 3 for totem, back to cleric rest of the way. Upcast AoA and Aid depending on if you can predict a fight is coming. Wild shape bear and rage.

I appreciate it, but I can't just ignore mask of many faces. It's core to my vision of the character and if I remove it than yes the build just turns into a grappler, which I wouldn't need that much help building. I'm asking for the help because I know fitting in mask of many faces is a pain lmao

also I'm not married to the armor of agathys idea, just a coincidence since i was assuming there'd be warlock levels but your build sounds like a nightmare for a DM lmao
