I've already said this before and I'll say it again, you guys are fantastic world builders. It's a shame that you guys are underated. It's basically a hidden gem in the world of DnD5e!

I loved the unique aspects and themes that you guys create, the crazy creatures like the golem locomotive to the entire theme of the Mages' war. I was very impressed with the high level of quality, thought, and balancing that goes into every bit of work you guys create. It shows the level of dedication, care, and passion the whole team and community has for the brand

I've been playing Dungeons & Dragons for 6 yearsnow, always looking for a new ways to play and things to try. Only (the) CriticalCrafting Team were able to keep up with me for now with their flavorful playeroptions and fun new monsters to defeat. Also who wouldn't want to get to play acowboy or real necromancer, especially that these are not the only great thingsthey offer.

I have been following the Critical Crafting crew for a while, and I even picked up the loremaster tier on Patreon. If you're thinking about looking into buying their work, or even supporting their Patreon, you will find it incredibly worth it, for both the quality of content you receiveand the versatility (you) can use it for. No matter if you're a player or a DM, they cater to all players. The community is sincerely one of the best places I have found in small company dnd content creators, with the people being incredibly friendly and with the true light of passion they all have for the game is amazing. It truly is a close community who always welcomes players and dms, new and old with warm and open regards.

(The first thing I noticed was) how beautiful the artwork was at first, but what keeps me coming back is how well balanced most of the magic items, monsters, and even subclasses/classes & races
