Boneclaw - CR 6 (Large Undead)

Boneclaws are towering undead that first appeared in the 3.5 Monster Manual III. As with most of the monsters I have been converting for my 5e campaigns, they were on my "use one day" list, but never saw the dark of night in either 3.5 or 4e. Anyway, they are due to shred some PC's soon, and so, I thought I would share my conversion for them.

I have slightly erred from their original incarnation, making them more deadly to melee attackers (with the Threatening Reach and Rampant Opportunist powers). If you don't like that, just remove the powers.

Hey! Who stole my piano?


  1. My party never survived to high enough level in 4th to fight them. In 3.5 the CR was significantly lower (4 if memory serves correctly) compared to the 17 or so it was in 4e. My only concern on the rampant opportunist ability is how it increases the damage per round. My only alteration would be to let it make two attacks of opp against the triggering creature instead of dex mod per round. Dex mod per round might require tinkering with the claw damage to get it where its not a quick TPK beast.

  2. Damage is very high, but framework is very solid mechanically. You really captured the tone and feel of what made them so scary in 3.5 (Combat Reflexes + Reach). I am going to use this as is, but with greatly reduced damage (more like 2d6+5).

    Nice work
