D&D 5E Most Used 5E Rule Book (Besides Core Books)?

[Reynard]

What 5E rule book (not adventure or anthology), WotC or 3PP, do you use most when running or playing 5E BESIDES any of the 3 core WotC books (PHB, DMG and MM)?

I find myself going to the LevelUp Monstrous Menagerie most -- not just to use the monsters in it, but to build both encounters and new montsers. I have yet to have a situation where the math for either steered me wrong.

What about you? What 5E rule book do you refer to and use most?

I was going to say the box sets, but they are not rulebooks. I guess I have a couple websites that I use to modify monsters and update statblocks. I do not have many other books like Tasha's and Xanathars.

For me it's monster books, with 3rd party stuff actually taking the lead over WotC - the various "Tome of Beasts" volumes and the "Monster Manual Expanded" books.

(If it's relevant: I've only used the 2014 ruleset. I don't currently intend to update to 2024, but if/when I did I'd probably then drop the use of the legacy books, both official and third-party - I like clean slates.)

Xanathar's, for sure.

My most-used third-party book is probably the Tome of Beasts from Kobold Press.

1E DMG.

But to answer the question as asked (and anyway, the 1E DMG is still a "core book" even if not a 5E book), I guess Flee Mortals! But even that, I have not used very often, or used anything in there as written when I have. Some of my players have subclasses from Tasha's and Xanathar's but that doesn't make me have to refer to those books very often.

Xanathar's, or Monster Manual Expanded II.

I'm hoping soon it will be my Bestiary Malfearous or Amberos Campaign Guide - working on revisions to both (rejiggering CR's for the former, reviewing/updating lore and reformatting for the 2nd).

I'm currently waiting on something like 5 Kickstarters so; i'll get back to you.

This is a tough call between Xanathar’s, Tasha’s, and The Explorer’s Guide To Wildemount.

 

[Dragonhelm]

We use Tasha's quite a bit in the games I play in because of the psionics content.

In one game, we heavily use Dark Matter, by Mage Hand Press. It's a great science fantasy add-on for D&D.

Xanathars. Taahas is unbalanced mess.
