Of course you can incorporate them :-) That is the purpose of my creations - to be used by other DMs for their campaigns!

A few updates:

First, the Elite Assassin received a major update: https://www.dndbeyond.com/monsters/3408594-assassin-of-the-crimson-blades

Then, there is the Knight of the Dark Flame, an evil paladin similar to a Death Knight: https://www.dndbeyond.com/monsters/3408618-knight-of-the-dark-flame

Then, there is a new subclass that is all about Beholders: the Dreamspawn sorcerer. https://www.gmbinder.com/share/-NNmVyWMtrwON22H9n9K

And lastly, there is an artifact for the dwarves among us, a hammer known as the Father of the Forge: https://www.dndbeyond.com/magic-items/5141701-father-of-the-forge

Another update:

First, I created Negankerdak, the legendary sword from Clamavi De Profundis's songs, as a magic item: https://www.dndbeyond.com/magic-items/7041490-negankerdak-the-unforged

Then, there are a couple more magic items:

• The Raven Scepter for those who worship the Raven Queen: (rare): https://www.dndbeyond.com/magic-items/6813352-raven-scepter
• The Totem of the Predator for wild-shaping druids to enhance their animal forms (rare): https://www.dndbeyond.com/magic-items/6841796-totem-of-the-predator
• And finally the Staff of the Winterlands for all those who love winter as much as I do: (very rare): https://www.dndbeyond.com/magic-items/6841971-staff-of-the-winterlands

And then there are two new monsters, the Vonindod from Storm King's Thunder -  https://www.dndbeyond.com/monsters/3682723-vonindod - an adamanitne dragon-slaying colossus built by giants, and the terrifying Swamp Hag - https://www.dndbeyond.com/monsters/2263827-swamp-hag.

Hello Semako!

Been wandering if you still planing on doing the metalic greatwyrms.

Thanks!

Sorry for the long waiting time :-) I still want to do them eventually. For now, I have some other new monsters and an item:

• The Eldritch Lich, a powerful eldritch horror and necromancer at the same time: https://www.dndbeyond.com/monsters/3592234-far-realms-lich
• Ophelia, the Flamebearer, archangel and steward to Lathander: https://www.dndbeyond.com/monsters/4468506-ophelia-the-flamebearer
• Baphomet himself, the master of the endless maze: https://www.dndbeyond.com/monsters/4468498-the-horned-king
• Lumeris, the glaive of Mechanus, a perfect weapon for servants of Primus, the One and the Prime: https://www.dndbeyond.com/magic-items/5409022-lumeris
• The True Soles, the boots that have seen everything: https://www.dndbeyond.com/magic-items/7971663-the-true-soles

I also realized I completely forgot to add my Metal Domain cleric (https://www.gmbinder.com/share/-NhX82cv6ToYVSCPS3qO) to the list.

Love your stuff, especially tharizdun, I noticed you were willing to do other people’s request's so I was wondering if you would be willing to do mine? Have you ever heard of the monster called the “Genius Loci”? It’s a monster from 3.5 that hasn’t been well adjusted to 5e by anyone yet. It’s practically a living moon so I imagine it would be ungodly strong

I will take a look at it, thanks for the suggestion!

Meanwhile, here's something else:

• For all those who want to fight for the industrial revolution - because a world powered by steam is  the future they desire and natural resources don't need to be protected, for those who oppose the Oath of the Ancients - here's the Oath of Steam paladin subclass: https://www.gmbinder.com/share/-ODqrcRhvPcZLUzrskWr
• When a beholder has a nightmare of getting stung by a bee, the result is the dreaded Beeholder: https://www.dndbeyond.com/monsters/5097709-beeholder
• At beer festivals and in taverns, the Beerholder is at home: https://www.dndbeyond.com/monsters/5097796-beerholder

you good sir, are a true master of monster creation. I can't wait to feed your greatwyrms to my magical armor that absorbs dragon materials to grow more powerful, their scales will give my Living Dragon Armor of Thorin Anvilfallen some amazing effects.
