I made a CR fifteen none player character and it is supposed to be a Batman like vigilante. Is it CR fifteen, too powerful, too weak? This is for Waterdeep Dragon Heist. I wanted to make a vigilante none player character so I made a stat block for it. Do you have any suggestions for it please let me know. This is designed to be able to fight the Xanathar in case anything like that comes up. This will not necessarily be used in combat let alone fight Xanathar but regardless feedback is helpful. Thank you, God Bless and have a nice day if the Lord wills it.

I'd estimate its CR to be over 28. Hard to be sure since it deals more damage than any CR 30 creature in the game... (I estimate its Offensive CR to be around 45 before factoring assassinate, which I had to extrapolate because obviously the chart doesn't go that high.)

Honestly, this is kind of a mess. I bet you overlooked the 24 shuriken attacks per round simply because of how bloated this stat block is.

Fixes:

• AC is arbitrary, put the source in parenthesis (natural armor, +2 full plate, etc)
• HP should include a dice calculation like 176 (22d8+66).
• The movement speeds are weird. It can climb faster than it can run? Glide isn't a speed, make it a trait (including how far it descends etc).
• You don't need expertise in every skill, consider cutting down and having regular proficiency here and there.
• Ambusher is completely redundant with assassinate, so cut that.
• Cunning action should be called reliable talent since that is the class feature you copied.
• Assassinate, sneak, sneak attack, and reliable talent, a +15 stealth bonus, AND 8 attacks per round (24 shuriken) is going to auto win any battle with over 1400 damage! Cut half of these features and we'll address actions later.
• Battlefield control is random and a bit much, cut that.
• Evasion is not a reaction, that should be in traits.
• All attacks need damage types.
• Multiattack is fine, but consider limiting the options.
• Martial arts is fine.
• Grapple has a lot to work on:
  • 2 different attack bonuses
  • Reduce damage or remove damage if this stays part of multiattack. If removed from multiattack, damage is fine.
  • Should be a ranged attack instead of melee
  • Should have a short range and long range (I recommend 30/60 honestly)
  • Should have a set pull distance (like 15~30 feet) and only get the BA attack if pulled within 5 feet.
• Shuriken is the biggest problem with the way it is worded:
  • It also has 2 hit bonuses
  • "Up to 3 targets" per 1 attack? Remove this line entirely. This is how it does 700+ damage per round.
  • Reduce damage. Should be a little less than melee usually.
  • You can probably just make the disarm clause part of the hit effect.
  • The save DC can be as high as 18 for CR 15.
• Training should be called cunning action since that is the class feature you copied.
• Consider renaming superior technique to something that makes sense and list what actions can be actually be taken, like search or use an item. "Abiltiy check" isn't really an action.
• Gear is too long. I get what you are going for, but just call it "fast hands" say it lets him use an item as a bonus action and put alchemist fire, caltrops, etc in special equipment. Anything that is not already an item, you can leave stated out.
• Legendary action remove multiattack and make it a single attack (particularly martial arts or shuriken, not grapple). You can add grapple but make it cost 2 legendary actions. Battle field training can just be use an item (see gear) or be removed to add a movement option.

After all this changes, it will at least be down to CR 20ish and we can continue tweaking from there.

Also Nightwalker is already a monster name, so consider rebranding.

Thank you for all of this and I called it the nightwalker to be named after nightwalker like batman is named after bats. I plan to not publish this or anything and use it for personal use so I might not change the wording.

 Like how stranger things names their monsters after completely incomparable D&D monsters solely because it is what they happen to be afraid of at the time. I gotcha.

I thought they were pretty close with Vecna, an undead demigod with a warped and twisted hand who is a “Lord of Illusions.”

I made some adjustments, how is it now? Thank you, God bless and have a nice day if the Lord wills it.
