Dungeons & Dragons' 2025 Monster Manual has brought many new creatures, but also introduced changes to the STAT blocks that already exist in the 2014 version of the book. Some have experienced minor changes, and others have received serious makeup that fundamentally changes the way of playing.

DUNGEONS & Dragons: 21 5e Challenge Monster
Knowing which monster has the highest challenge in D & D is valuable information if you are looking for a DM A game.
Some were spelled, and some were re -worked, and some were mixed with biological types. Here, we have some examples of the 2025 monster manual, the most important changes, and how it can be used in adventure or campaigns.

Kenku
They are a cursed monster now
KENKU is one of the many creatures that have changed biological types in the updated monster manual. They were able to fly and speak, but why they were classified as monsters because they lost their voices and wings due to mysterious curse.
When the curse of KENKU is released, it will be very similar to Aarakocra, creating an element of a biological type.
For the rest of the stat block, the only remaining technology is imitation. They no longer have a paragraph, and they use the magic dagger that comes back when thrown and Eldritch Lantern, which can access the Faerie Fire.
6
Death Knight
Proper legendary creature
In the same name as 'Death Knight', you expect that the undead will be a legendary creature that is worthy of its name, but not in the 2014 Monster Manual. In the 2025 edition, Death Knight got its name with legendary behavior, resistance and ability to resurrect in 1d10 days.
Death Knight is also an excellent example of a simplified spell casting in the biological statistical block. Death Knights have a certain number of use per order instead of having some spell slots, some of which are demoted to the legendary actions such as commands to spread their abilities.

Dracolich
Appropriate rich
Almost all adults and ancient dragons have a spellcast function with other updates for Moveset. This has already existed in some cases, but only as a proposal for the 2014 Monster Manual. Now they all have spells built into stats, which are upgrades that give more benefits to Dracolich than other dragon-injured creatures.

In this D & D Blights, their shells are as bad as bitten bite.
Another change in Dracolich (adult Blue Dracolich) is to include the Soul Gem in the stat block. There are also tables with ideas about places where jewelry can be hidden, such as the treasure spleen of rival dragons and the vault of Arch Devil.
4
Pit
Not everyone needs spelling
With the PIT FIEND, we can see the examples of several monsters that have removed special exemptions. This removes busy things for these creatures, allowing both players and dungeon masters to participate in their actions.
The interesting aspect of the PIT FIEND is to eliminate spell casting characteristics. Now, instead of casting the Fireball freely, Pete Mine must cast the fire chunks twice and recharge the ability before you can do it again.
3
Rich
It's simplified, but it's still fatal
Rich's statistical block has changed much from simple things such as larger armor grade to more complex factors, such as how the spells are cast. There are no more spelling slots in Rich, and there are other people who have a limited number of Will Spells and other purposes. Overall, there are few orders, but maintain the best spells of the group.

This adventure is suitable for low -level D & D parties.
The seemingly meaningless change is that there is a lack of can trips. If Rich is silent, it is important because it still removes the general method of completely invalidating the creature, in addition to the order to attack the party.

sun
Angel lie detector
Many angelic and angelic beings are similar to their evil enemies. They can only be killed in the native plane. This is often ignored by many Dungeon Masters because it is not included in the STAT block, but no longer: now Solars can be permanently killed when defeated in Celestia.
In addition, the photovoltaic has changed the set in a more helpful way as an allies. It can cast treatment wounds and eliminate curses by bonus action, and Slaycink is now part of multi -Texas action and is immediately death if the target is less than 100.
1
Tarrasque
Vertex predator
In essence, Tarrasque reflects the spell and reflects the entire adventurer, becoming an absolute fear on the battlefield. Certain elements of living things have been changed to focus on struggling, eliminating duplicate abilities, and focusing on creatures that cause a lot of damage.
The terrible beings were removed, which was a general 'big monster' ability and replaced by thunder. Belloz cannot be used as part of multi -art tags, but it causes excellent thunder damage, applies a terrible deaf condition, and has a rechargeable option, so creatures do not scream every turn.
In the case of basic attacks, the horn option has been removed due to duplicate, and the tail is now knocked down without storage. In addition, new legendary behavior, the world's shaking movement, and those nearby do not interfere.
