 * -|Common Skills=

- Great Sage, manga vol. 1


 * Water Blade: Originally a Common Skill, was integrated into Control Water which was then also integrated into Control Particles. It creates a highly pressurized blade of water. Fast enough to leave afterimages.
 * Flare Circle: An attack move that combines Rimuru's Ranged Barrier with a flame-generating magic circle and Flame Transformation (now integrated into Dark Flames), it seals the target in a boundary that prevents thermal energy from leaking out, and then burns the opponent alongside all the oxygen within the barrier. Any living thing that breathes air without having Resist Flame Attack (or better), or some other means of defense, will perish within it.
 * Hell Flare: An attack move that creates a Ranged Barrier dome five meters in diameter which burns the target to nothingness with temperatures of several hundred million degrees if compressed enough. Capable of breaking through even extraordinary resistance against Flames or Heat.
 * God's Wrath (Megiddo): A skill which uses Elemental Magic to form multiple very large magnifying-glass water constructs in the air. This focus the energy of the sun into a devastating heat beam capable of reaching thousands of degrees. The constructs disintegrate after use, but the energy needed to replace and maintain them is very little. Because they are clear, thin lenses of suspended water, the constructs are almost impossible to see. The size and number of lenses can be changed to varying effects: decimating 1000 armored soldiers in a single shot to killing a single target instantly and without sound. By using Water magic to create droplets of water in the shape of convex lenses in the sky, Rimuru condenses sunlight to the point where it becomes a massive laser beam which is similar to using magnifying glass. Due to the low requirements of water magic, the water droplets can continually be replaced when they evaporate. The Massive energy beam is a physical phenomenon, and therefore cannot be blocked by magic disrupting barriers.
 * Disintegration: The ultimate in targeted, destructive magic, which emits flashes of white light as it pours from Hinata's hands. It moves almost at light speed, as its holy power makes cells and souls vanish without a trace.
 * Melt Slash: An ability which infuses her strongest magic, Disintegration with her sword art. Hinata then turns into a beam of light and quickly approaches her target.


 * -|Magic=
 * Icicle Lance: Magic which creates multiple ice pillars which he fires at his opponents.
 * Warp Portal: A type of elemental magic which allows the caster to draw the same series of symbols at the entrance and exit. These symbols worked strictly as pairs, so stepping into a Portal would always bring you to the same destination.
 * Anti-Magic Area: Magic which is formed by rewriting the laws of the world to create a barrier which prevents the usage of magic.
 * Summoning Magic: Magic which can be used to summon other beings such as spirits or demons.


 * -|Resistances=
 * Great Sage: Prevents Rimuru's deep psyche from being interfered with, which blocks attempts to read his mind or memories.
 * Otherworld-Reincarnator: Has a strong soul which allowed Rimuru to survive the crossing between worlds with only his soul. Possesses multiple Unique Skills which are the shape of the mind itself and are inscribed into the soul, so they require a strong soul for the user to hold them, even more so with multiple Unique Skills.

 * Ultimate Skill User: As an ultimate skill user Rimuru cannot be affected by low-level skills. Ultimate skills are devices to grant access to the ultimate principles of this world. That is why, in order to combat against an ultimate skill, one must employ an ultimate skill as well.

Details
Using Great Sage, he can quickly read a book by copying it completely. Simultaneous utilization of Great Sage and Gluttony allows the high-speed copy and review of the magic books that he holds in his hands. With that, he can postpone checking the content of the book for a later time. Unfortunately, it is not possible to be able to use magic just by copying books. But, taking and copying it, he's able to make the index of the magic books that he wants. After this, it's necessary for him to study them one by one. Taking that into consideration, it can be said that Rimuru holds a great amount of knowledge regarding magic as well as being speculated to be able to use most of the magic in those books, if not all of them.

After evolving into a Demon Slime, the ability to freely change between material and spiritual bodies was added. As a result of the evolution, his total magical energy greatly increased. Compared to the original amount, it was ten times as large.

He can use skills that don't rely on magical energy such as raising his abilities using fighting spirit technique with Herculean Strength in addition.

Thanks to Hakurou's guidance, his skills with the sword was improved.

Note: This contains spoilers from past the light novel

{{Hidden|Click "show" content| He was able to analyze the Summoning Magic he first saw during the adventurer exam and acquired the skill to use them.

After fighting the Guardian of the Labyrinth, Rimuru has the ability to create golems. The abilities of the Golem can be added through the possession of a spirit or a demon as Rimuru made them inhabit the Golem. The outward appearance of the golem is created according to his imagination.

Using Manas: Ciel, Rimuru can copy space manipulation techniques simply by seeing it, such as when he copied the Unique Skill Restrainer which belonged to Gozurl. Like this, Rimuru can also copy practically any other Skill or Magic as long as he has seen it.

After the fight with Yuuki, Rimuru gained the ability to use the Instantaneous Movement which lets him travel across Space-Time at will. Using this ability, Rimuru was able to travel to his old world where he saved his past self Mikami Satoru from death. He was also able to return from the place beyond time where he was exiled to by Yuuki. The ability as described is the ability to reach the desired point instantly across space and time.

Mimic/Mimesis

 * Armorsaurus
 * Giant Spider
 * Giant Bat
 * Centipede
 * Orc
 * Dragon
 * Undead Elf

When a certain amount of damage accumulates, the mimicry wears off. Afterward, there are no damage transfers to his slime body. Because the skill Mimicry utilizes Magic Essence to create a new body, the main body cannot be damaged. There are two restrictions on this skill. After Mimicry wears off, he is unable to transform for the next 3 minutes, and the other was that mimicking a demon/monster required a certain amount of magic essence. The amount of magic essence required is relatively insignificant, hence, it is not an issue, and there is no duration limit to the skill. The reason for black fog when mimicking into monsters is to compensate for the missing parts.

Fusion
He can use the skill『Fire State』in his slime form, allowing his aura to turn into flames. His surface temperature increases to 1400 degrees Celsius and his body becomes a weapon.

Equipment
A magic mask left by Shizue Izawa. As its name implies, it suppresses demonic power. It also serves as a treasured memento of Shizue, as it is the only remaining possession of Shizue which Rimuru possesses. Although Rimuru gave the mask to Chloe Bell, he has since made a copy to wear himself. He received dark leather guards from Garm. It is made of glossy linen - first-class silk that feels wonderful to the touch. Putting the silk to his body, it immediately changes the size to fit him. After mixing with his magic, it became as if a part of his body. Even in his adult form, the clothing grows appropriately. This clothing absorbs the aura of its wearer and can change its appearance. Rimuru's clothing turned jet black to match his aura. Even if this clothing rips, as long as it absorbs his magical energy, it can repair itself. The materials used came from the previous Fanged Wolf leader. But, due to the wolf clan's evolution, the fur had turned black. As an extra bonus, it seems that the fur had quite some magical energy stored in it. It has tremendous defense power. This attire happened to have become a magic item. It will always perfectly fit the one who wears it. In other words, even if Rimuru turns into his adult version, the clothing won't rip. This gear appears to evolve the longer it is exposed to Rimur's aura. Rimuru equipped himself with a demon sword, a Magic Sword of high-purity Demon Steel inserted with high-purity magic stones/gems he created a sword using Bladed Storm Crystallization and Bladed Flame(Scorch): Crystallization from Void God Azathoth and named it The Sword Of Tempest, its a Genesis grade sword. A sword created when Rimuru and Wisdom King Raphael use the core of the True Dragon Veldora to modify Rimuru's katana. It can create a sound wave powerful enough to literally separate the sea in two and cut all for kilometers on his path. A Genesis Class Sword. Communication artifacts between the Demon Lords. A sword created by Rimuru like Veldora Sword but in a different situation. A Genesis Class Sword. Comparable to Veldora Sword. It was stated he could ask Velgrynd to become the core for his sword but it will be a difficult task. It is only mentioned in the Webnovel and never truly used. Rimuru got this after He Defeated Yuuki Kaguzuraka. It's a Genesis Class Sword. It contains the power of Veldanava.
