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
