UPDATE: We have an updated tier list for That Time I Got Reincarnated as a Slime ISEKAI Memories for the current month. Read it here.
Note that this tier list is for Battle Characters in Slime ISEKAI Memories. For Protection Characters, you should be using the one that gives increased elemental damage according to the enemies’ weakness.
Since this game is entirely PVE (for now), our tier list will be ranking the characters based on how useful they are for this content. With that out of the way, let’s dive into the list:
SS Tier
The best of the best—one skill sets them above all the other characters.
[Dragon Majin] Milim Nava
Just like in the anime, Milim is THE character everyone is scared of and that is reflected well in the game. There is a good reason why [Dragon Majin] Milim Nava aka Wind Milim is at the top of the Slime Isekai Memories tier list.
Her skill, Dragon Power, increases your Soul of Combos (aka ultimate) damage by a whopping 60%. This skill alone is the most busted skill in the game. Thanks to this skill, Wind Milim lets you clear stages well above the recommended EP and makes her useful in any element team.
[Seal Releaser] Veldora Tempest
Joining Wind Milim in this tier is the new human form Veldora. He is a dark element physical unit who possesses the same (but slightly weaker) skill as Wind Milim. Veldora can increase your Soul of Combos damage by 50% instead of Milim’s 60%. Even though it is 10% weaker, it is still incredibly busted.
Theoretically, it is possible to use both Veldora and Wind Milim’s skill in the same turn if you have more than 100 skill points (achievable through Protection Skills). Realistically, by the time you already activated the Divine Protection, have enough skill points AND filled enough characters’ Secret Skill gauge, using both Wind Milim and Veldora’s skill on the same turn is overkill. Use either Veldora or Wind Milim in your team, but not both at the same time.
S Tier
Extremely useful characters who have a place even in teams that are not of their element.
[Budding of Deep Green] Treyni
Not only is Treyni the best healer in the game, but she also has a single target ultimate, making her perfect for many of the harder endgame content. She’s also the tankiest character in the game with the highest DEF and will save your team more often than you can count. Since a lot of the game’s missions require you to clear them without any character dying, Treyni will help you achieve that.
[Queen of Yule] Luminus Valentine
Luminus’ skill heals 5% less HP than Treyni’s, but also costs 5 Skill Points less, making her a fantastic alternative to Treyni. As a physical wind-element character with a single target nuke, she’s a must-have support for wind teams, but also great for other elements. She’s also the only character in the game at the moment who can change 1 Soul of Divine Protection and 1 Soul of Secrets into up to 2 Soul of Skills.
[Chancellor of Tempest] Rimuru Tempest
Both of [Chancellor of Tempest] Rimuru Tempest (aka Space Rimuru)’s skills are incredibly useful. All of Creation is the strongest ATK buff in the game, while Magic Sense is a 20% DEF buff that lasts two turns. When you have 6 of the same Souls, pop All of Creation for incredible damage. Because of this, Space Rimuru is the best buffer in the game and will fit into any team.
[King of an Armed Nation] Gazel Dwargo
Single target ultimate are generally better than multi-target ones because most of the game’s harder content features a single, powerful enemy instead of a group. Guess what? Gazel is the best single target nuker in the game. All of his buffs focus on increasing his offensive power (ATK, Crit rate and Crit damage). Above all else, his skills have very low cost, so you can activate expensive skills such as Space Rimuru or Wind Milim’s buff on the same turn to reach insane damage.
A Tier
Great characters who are the go-to picks for teams of their respective element.
[Instructor of the Flashing Sword] Hakurou
Hakurou is the definitive single target nuker for wind teams. Even though he has an amazing buff in the form of Keigoku, which reduces enemy DEF and increase your team’s Crit rate, its expensive cost means that you’ll rather be choosing Wind Milim or Space Rimuru’s buff 9/10 times. This is why I put Hakurou below Gazel in A tier as he has less synergy with the other top tier units. Still a great pick regardless.
[Conquerer of Flames] Shizue Izawa
Your single-target fire DPS, Shizu may not have crazy buffs like the other characters before her, but she has the great ability to change 2 Soul of Divine Protection into Soul of Secrets. Since the current meta favours Secret Skills, being able to build up your ultimate gauge faster is fantastic.
[The Black Progenitor] Diablo
The hardest-hitting single target nuker for dark teams. As we mentioned in our coverage of the Diablo event, he’s extremely similar to Gazel, just with lower ATK and with a Soul change instead of a second buff. If his Soul change changed 2 Souls instead of just 1, I would’ve put him in S tier with Gazel.
[Steel Annihilator] Shion
Your multi-target dark DPS, Shion is one of the few units in the game who can buff pierce rate and power. While it’s a great buff, she has the same issue with Hakurou in that you’ll rather spend your Skill points on Wind Milim or Space Rimuru’s buff instead. In addition, there is less synergy for pierce, as compared to ATK or DMG buffs from multiple characters that stack.
[Arch Golem] Beretta
Beretta is the dark team’s single target nuker. She’s basically Shizu, but for dark teams.
[Harmonizer of Majin and Humans] Rimuru Tempest
Water Rimuru is the only character in the game who can reduce the enemy’s Soul of Secret gauge, effectively delaying the enemies’ ult by 1 or 2 turns. On top of that, he can also heal. While I’m sure some of you reading this may feel that Water Rimuru deserves to be placed higher on the tier list, hear me out.
While delaying an enemy’s ult can mean the difference between clearing or failing the mission, it’s simply not as synergistic of a strategy as stacking offensive buffs and finishing the enemy off. It also doesn’t happen often enough to make it as vital and when you do have a unit that’s in danger of dying to an ult, switching them out is the better, more cost-effective option. Treyni is higher due to how much more heals, plus she has a single-target nuke, as opposed to Water Rimuru’s multi-target ultimate.
B Tier
You’ll still want these characters in teams of their respective elements, but their skills aren’t as useful as the other characters ranked higher in this Slime ISEKAI Memories tier list.
[Holy Princess] Shuna
The second single-target nuker for light teams. [Holy Princess] Shuna can change your Soul of Secrets into Soul of Divine Protection. This is great for achieving higher DPS, but 9/10 times, Soul of Secrets is preferable as using ultimates are preferable to using Divine Protection.
[Spy in the Shadows] Souei
Souei is the water team’s single-target DPS. Basically fills the same role as [Holy Princess] Shuna as he can change Soul of Secrets into Soul of Skills.
[Samurai General of Hellfire] Benimaru
Benimaru is a great multi-target fire DPS. His buff lets him increase his own ATK which is great for finishing off multiple enemies. Sadly, there is not enough multi-enemy endgame content that is difficult enough to warrant Benimaru a higher placing in the tier list.
[Awakened Demon Lord] Rimuru Tempest
Demon Lord Rimuru is an amazing dark-element magical unit with an incredible self-buff that increases both his crit rate and crit damage. He’ll easily rank higher on the tier list if his ultimate hits a single target, but because it is multi-rarget, he shares the same problem with [Samurai General of Hellfire] Benimaru.
[One of the Oldest Demon Lords] Milim Nava
The earth team’s single-target DPS, Earth Milim is vastly overshadowed by her Wind variant. She can change Soul of Secrets into Soul of Divine Protection while her other skill buffs the team DEF, making her basically a carbon copy of Souei.
[Manifestation of the Dragon] Milim Nava
A magical damage, dark character with a single target nuke, Dark Milim has the same soul change as her earth version, but with a worse second skill that raises her team’s critical resistance while also buffing her own critical rate.
[Tempest Star Wolf] Ranga
A multi-target space DPS, Ranga also features a Soul-changing skill, capable of changing Soul of Secrets into Soul of Skills. Unfortunately, his other skill, which buffs pierce rate, is rather underwhelming.
C Tier
These characters have noticeably lower stats than the ones in the tiers above.
[Pink Ogre of Holy Light] Shuna
Everyone gets [Pink Ogre of Holy Light] Shuna as a pre-registration reward. She has the lowest stats out of all the 5★, but still makes a good pick for wind teams. She can change Soul of Divine Protection into Soul of Skills.
[Valiant Kijin] Benimaru
The only 4★ character that I’m placing on this tier list, and the best 4★ character in the game. This is thanks to his skill, Lion Dance, which buffs his Crit rate by 80%! You can easily achieve 100% Crit rate or close to that through means such as traits. On top of that, Lion Dance is an incredibly cheap skill with a low cost. [Valiant Kijin] Benimaru is a light-element multi-target DPS, which is a shame because if he was single-target, I’d have placed him higher in the tier list. A great investment for free-to-play players.
D tier
All other 4★ and 3★ Battle Characters belong here. You can still use them in your teams as the game is PVE and not PVP-focused. Generally, you’ll want to use the characters above, though, due to superior stats and skills.
