D&D 5E Pathfinder to 5e Monster Converter

I've been working diligently on creating a monster converter for Pathfinder to 5e: 5e Monster Converter

I have based my converter off these conversion rules.

The goal of this converter is to give a pretty solid guestimate of all the basic features of creatures and as many advanced features as possible.

How it works: Copy a whole stat block from either PFSRD or an adventure path book into the textarea. It will automatically convert. If it does not please open your console (F12) and let me know what error you got.

The converter currently does all these basic things:

  • Size, Type, alignment
  • AC
  • HP, HD
  • Speed
  • Abilities (Str, Dex, Con)
  • Skills
  • Senses
  • Languages
  • Challenge
  • Traits (some)
  • Multiattack
  • Attacks
  • Special Attacks (some)

Some items that I'd love some help on:
AC, Challenge, Traits, Special Attacks, Immunities.

AC: I currently use either the armor listed under "gear" or "other gear" or the formula in this google doc. I have tested 161 creatures comparing their pathfinder version to their 5e version and seeing how close my formula got. The formula isn't perfect so please let me know if you have any better ideas.

Challenge: I calculate the average HP and compare it to the table on DMG 274 (I find the middle of the range and compare to that). I determine a defensive CR based on that. I then calculate the damage per round from all attacks (including multiattack) and compare that to the same table (I find the middle of the range and compare to that) to get the offensive CR. I then average those two numbers to get an overall CR - just as prescribed. If anyone has any suggestions for how to improve this please let me know.

Traits: I currently process some items based on the SQ field from pathfinder. I'll be adding more over time. I'm currently working through Skull & Shackles monsters to see how they compare to the ones I did manually (up to book 3). Please let me know if you know of a common one that should be added and preferably the 5e wording for it.

Special Attacks: Same as traits really, just from the special attack(s) field.

Resistances & Immunitites: For the most part 5e got rid of 50% of the ones from PF. It will be quite difficult to make this work in a general way.

I appreciate any feedback that you give

Nice to see you posted this here, I meant to respond on Reddit, and suggest you do so. Also does this convert 3.5 to 5e or just Pathfinder stats blocks?

This is amazing! I'm currently running RoTRL in 5e and this is a god send, will save me so much time.

Thank you so much [MENTION=6670944]Kryx[/MENTION]

I've been posting updates here. My git for this is set to private, but I'll continue to post updates here since this is where it has got the most response.

Spells got converted a bit ago - that was the last main thing. Since then I've been working on my roll20 sheet and scripts.

Is there something specific that you're missing?

Hi Kryx, I'm new to D&D in general and have started 5th edition, I love the variety of monsters that pathfinder has so I'd love to bring them into 5th edition, so thanks very much for your converter! It's a great resource, especially since I love the pathfinder pawns but not a whole lot of them cross over with 5th edition. Saying that, does your converter work for everything in the bestiary? I can't seem to get anything more advanced to work, things like dragons and bigger or more challenging creatures for example. I was wondering if the converter still hasn't been updated with those creatures or if it was just me doing something wrong. I'm copying and pasting from the PFSRD so I'm not sure. Thanks again, and if you could let me know that would be much appreciated good sir!

All the basic stuff should work for all monsters besides swarms.

Advanced stuff has to be done on a case by case basis - it's basically data entry.

Currently those hours have been dedicated to my sheet on roll20, but I plan to work on adding more special attention attacks and stuff soon.

If anyone wishes to help with converting special attacks or special qualities to 5e let me know.

Thanks for getting back to me. I don't need any of the more advanced creatures for the foreseeable future anyway, but hopefully you will have more time to add stuff down the road. I might just follow the guide and do it by hand. Thanks again.
