These are not rules in the traditional sense. These are suggestions a DM might use to facilitate a subclass change in their game. Under " Training Time", we see (emphasis mine): The next subsection, " Training Time", goes on about how changing a subclass might take time, money, and/or a quest. How does this work with the previous paragraph's rule of only changing subclasses when a character gains a new subclass feature? For example, if the character needs time to train or complete a quest, I'm not sure how you could align that with gaining a new subclass feature. The swarmkeeper has a magical connection with some type of natural swarm. This could be bugs, birds, or even pixies. Using the swarm you gain Mage Hand, and the swarm can also boost your damage rolls, move enemies, or even transport you by 5 feet. Creature type. You are a humanoid. You determine your appearance and whether you resemble any of your kin.

In addition to these brand new subclass options, the book also reprints some other archetypes. These options include subclasses originally found in Mythic Odysseys of Theros, Guildmasters’ Guide to Ravnica, and Sword Coast Adventurer’s Guide. You can read our review of each of them below! Telekinetic jumps out to me. A boost to your stats like Fey or Shadow Touched, invisible Mage Hand with no verbal or somatic components, and you can telekinetically push people 5 feet as a bonus action. There is a lot you can do with this, and it's especially great on a class who doesn't typically have a lot to do with their bonus action, who can now just keep pushing poeple around, into spells etc. A creature can also willingly let themselves be pushed, so you can also use this to push your allies out of harm's way. In either situation, I would work the subclass change at their next level up. In the first scenario, if they give me time to work in some plot, there is going to be some significant plot leading up to their next level up that will culminate in a change of subclass when they finally level up. This is a mighty skill for any adventurer to have, but it’s especially useful for bards, rogues, and any other talented expert that might be lovingly called a “skill monkey.” By granting you proficiency in an extra skill and expertise in any skill you’re proficient in, it makes you a master of whatever craft you choose to specialize in. SlasherI present rogues as a use case for why I would break from the guidance given in the book. Rogue subclasses have a huge gap in features. Once a rogue gets their first subclass features at 3rd level, they don't get another until 9th level. Akin to the Fey Touched feat mentioned earlier, a character might gain the Shadow Touched feat from being lost in the drab and ghastly landscape of the Shadowfell. In addition to improving one of your ability scores, you also gain the ability to cast invisibility, as well as another shadowy spell. Skill Expert

The first paragraph under that section heading says that characters can change their subclass when they would normally gain a new subclass feature. The book also reprints the original three artificer subclasses from Eberron as well. Wrapping Up Our Tashas Cauldron of Everything New Subclasses GuideNothing in Crusher, Piercer, or Slasher says the damage has to be melee. I mean. Piercer would even work with the Ice Knife spell! You’ve undergone rigorous martial training in your downtime, though not enough to become a full-fledged fighter. Instead, you’ve learned how to fight with a particular weapon, allowing you to gain a Fighting Style from the fighter class. Don’t forget that there are a handful of brand-new Fighting Styles in Tasha’s Cauldron of Everything including options for fighting bare-handed, fighting blind, and fighting with thrown weapons. Gunner The College of Creation centers on the “Song of Creation,” the primeval harmonies that pre-exist the known world. These bards draw on this song using art, music, and poetry. As with the Psi Warrior, the Rune Knight is another highly anticipated part of Tasha’s Cauldron of Everything. This subclass can create magical runes that enhance their gear. You gain in number runes you know by your fighter level up to a maximum of 5. These runes allow you to essentially enchant mundane items. The benefits of these runes vary, with many buffs to sight and saving throws.
