my dm used this and now im cheating by looking at the stats lol

Ha ha what if he finds out

Considering how weak this is, i think i can beat it with my level 5  rogue. No seriously. In the west marches server we have we have a mechanic where you can spend slots equal to your proficiency bonus. It includes stealth, worth 4 slots, to be able to attack with adv and get a surprise round. I play an arcane trickster, not an assassin, btu i also get to use 2 slots to set up a trap worth 2d10 damage. (The  favorability slots is what it's called. If anybody is interested in how it works, tell me and i can tell you the details). Anyways I use booming blade alot, as well, so i think i can, considering i have elven accuracy and a +7 to hit with my +1 rapier and my +1 longbow, i think im set. Im gonna test it on avrae and reply backhere on results

How big/tall is it, we are in a campaign but we do not know if he is bigger than a tortle, and orc, a kenku, or a tabaxi

No, in the original book, Frankenstein's creature was extremely intelligent and articulate. He actually taught himself how to speak and how to read, just by listening to a family and perusing books. He even killed a person later, and framed one of Frankenstein's close people to provoke him, and throughout the book he was one step ahead of his creator. 

This make this frankensteins monster, simply change it's intelligence to 16 or something. Was very well read. Also maybe do something to its charisma. Was a charming fellow, just repulsively handsome. Comes with being made of the stitched together parts of other handsome people.

How are Golem weapon attacks considered magical? just +1 if it happens to pick up a club, for example?

Nice toes

so this is what i should use for skaabs

A great example of the blurry line between undead and constructs.

I want to make one for my necromancer..... 

for those playing the Planescape campaign:

yeeea this is BUSTED as hell to start the campaign of with. To someone who wasnt cheating and looking at the stat block, there's no reason id figure this wasnt feasible for 7 lvl 3's to fight. My party and I barely survived because half of the party was relying on Martial damages to hit which this this is IMMUNE??? to.

I understand that the whole characters dieing and respawning is a whole mechanic but the problem is that the golem doesnt even do that much damage to really ward off a larger party of players. I feel like the Planescape campaign needed to have a much higher tier, more obvious "dont fight this" kind of monster like a Dragon or Demon or some such. In the context of this campaign, the Flesh Golem appears to be more of a larger sized zombie. Either the players should get adamantine weapons or this thing needed a variant bc the long combat sure wasnt fun. 

god he's so cute

We have Frankinstein's monster stat block. 

I know its been a few years since you posted this but to clear things up Frankenstein's Monster (Adam?) was a bit of a genius.  The story "Frankenstein" is told by him from his perspective.

Ooops...reading further I see a number of folks have already pointed that out.

Apologies.

Been a long while since I read "Frankenstein" but I don't think lightning, or any other electricity, had much to do with the creation.  Wasn't it more about alchemy/ chemistry?  I seem to remember the "monster" came to life while Vic was at class.

Can people post homebrews on these things???

I usually make Flesh Golems Goliath size or smaller but the real question is how much of how many humanoids did you use, I like to consider it to be about 20% from like 6 or more humans, also for detail this could contain elf, halfling, human, goblin, hobgoblin, bugbear, orc, Gnoll, or similar humanoid fleshes. Like give it a swimming speed and make it be a merfolk or merrow Flesh Golem. Or you could add racial traits from multiple races such as Stone Endurance from Goliath, Saving Face from Hobgoblin, Flight from Aaracoca (if that's how you spell it), and lastly aggressive/bite from gnoll. Making the most terrifying Flesh Golem ever. This would likely increase its CR by 1 so it would now be a CR 6 maybe.

If your DM agrees there could be some simpler ways to make this. Don't get me wrong this still would be a extremely expensive and complicated thing to do

 Well it depends on what kind of creature you use

Huh im kinda sad they removed its fire vulnerability and replaced it with the disadvantage. Still solid though
