Gotta confuse the body , right babe ? <| sep |> You ' re probably from the North East , Cali , or not even American <| sep |> Some days are indeed fuck it days . God knows I can ' t remember a thing I did in a month or two in the worst days . <| sep |> This is a really really cool creature I have to say . I like it a lot . CR looks to be 3 , so for a level 6 party you could pretty much go one surgeon per party member . I think I ' d steer clear of increasing the saving throw DC every time they ' re injected . Thematically I like the idea but if these guys are getting three attacks per turn then the DC is going to become insurmountable quickly , which might result in anger from your players . My suggestion instead would be to increase the DC to 13 standard for a CR 3 monster and then if a player is stuck with a needle , they have disadvantage on their next save . This works better within the bounded accuracy and just general rules of 5 th Edition and it will bring tension rather than frustration to your players . DM The surgeon sticks you again . Your head swims , your limbs feel leaden , and you ' re having trouble getting your body to respond . Make a Con save at disadvantage as the poison takes hold on your system . Oh and lastly , their to hit should be 6 . They have 4 from Dex , and a typical CR 3 monster has 2 proficiency . Basically change their proficiency and alter skills and to hit accordingly . Seriously though , this a really cool creature . Going to try to work it into Curse of Strahd ! EDIT Take a look at the Basilisk actually . Weirdly its Petrifying Gaze isn ' t listed in the monster abilities on p . 280 of the DMG , but it might help you balance these guys . I think you ' re pretty close anyway .
