Inner Ability can be a big boost to your damage and really round out your character in terms of what it needs, like critical rate or attack speed. This guide will tell you the best Inner Abilities for every class in the game assuming you have legendary Inner Ability.
Keep in mind that while getting 3 perfect lines is great it is not the best use of your Meso. After your equips have great Starforce (17+) and potential lines then you can start perfecting your Inner Ability.
The best Inner Ability for every class is Boss Damage %, Attack Speed +1, or Passive Skills +1 for your prime line. If you’re making a farmer Meso and Drop % are the best.
When To Work On Your Inner Ability
Inner Ability should not be your main concern when starting out and should be perfected once you hit some sort of threshold with your equips. These are the best steps to take when creating a main or legion/link mules.
- First get your Inner Ability to Epic or Unique and lines of Meso and Drop ASAP
- Leave it there and level up to 200 and up (Do a little Starforce upgrading along the way to help you level)
- Once you are done with Starforce work on your potential lines
- Then push to Legendary Inner Ability
- At this point you need to make a choice of continued farming/leveling or bossing
- Get that 1st line of Meso or Boss depending on your choice and class
- When you’re no longer farming and your gear is done, check the list for your class and go for your perfect Inner Abilities.
Things to note would be, you’ll want to keep Meso Obtained and Drop Rate for as long as you can since you won’t be doing harder bosses till around 220+.
In the beginning it is relatively easy to get to epic and unique on just the honor exp you’ll find from farming. After unique, use Miracle Circulators to get to legendary.
Spending your money on Starforce and Potential will give you the biggest gains.
Warrior Class Best Inner Ability List
These Inner Abilities are best in slot but, if you roll Boss Damage % on a character that doesn’t have it as it’s 1st line it’s still a great option (If you actually do bosses on that character).
Warriors typically have less base Critical Rate but can be made up with Legion Artifact, a high Legion, and links. If you are newer, settling for some crit rate will help you early on.
Anything with the option of Cooldown skip as the top line is very RNG dependent. You can choose something like Boss Damage instead if you want more guaranteed damage.

Magician Class Best Inner Ability List
When it comes to Magicians, Attack Speed and Boss Damage will be your best friend. Kanna has 2 sections since they are so great at farming and Bossing. For farming 20% Meso is absolutely necessary.
Lara is different from other mages and since she relies on her summons Passive Skills +1 is better compared to Attack Speed +1. (will update this if this is tested and changed) Choose +8% damage over Critical Rate if you can reach 100% Critical Rate through Legion and Links.
| 1st Line | 2nd Line | 3rd Line | |
| Battle Mage | 20% Boss Damage | +8% damage when attacking targets inflicted with Abnormal Status | 21 Magic Attack |

| Evan | Attack Speed +1 | 10% Boss Damage | +8% damage when attacking targets inflicted with Abnormal Status or 10% CoolDown Skip |
| Fire/Poison Arch Mage | Attack Speed +1 | +38% Buff Duration | 10% Boss Damage or 20% Critical Rate (if lacking) |

| Kanna (Farming) | 20% Meso Obtained | 15% Drop Rate | 21 Magic Attack |
Thief Class Best Inner Ability List
The Thief class has a lot of burst characters so a flat Boss Damage % is great.
| 1st Line | 2nd Line | 3rd Line | |
| Cadena | 20% CoolDown Skip | +8% damage when attacking targets inflicted with Abnormal Status | 10% Boss Damage |
| Dual Blade | 20% Boss Damage | 38% Buff Duration | 10% CoolDown Skip |
| Ho Young | Passive Skills +1 | 10% Boss Damage | +8% damage when attacking targets inflicted with Abnormal Status |
| Khali | 20% CoolDown Skip | 10% Boss Damage | +8% damage when attacking targets inflicted with Abnormal Status |

| Xenon | Attack Speed +1 | +8% damage when attacking targets inflicted with Abnormal Status | 10% Boss Damage |
Bowman Class Best Inner Ability List
When it comes to Bowman classes they usually have high Critical Rate (Sharp Eyes) already so it might be confusing to see Critical Rate on the list. This is because of the V Matrix Skill, Vicious Shot. This skill takes your extra Critical Rate and puts a % of it into your Critical Damage. This is amazing since Critical Damage is one of the best damage multipliers in the game.
The Magician link skill helps you take full advantage of the 3rd line.
| 1st Line | 2nd Line | 3rd Line | |
| Bowmaster | 20% Boss Damage | 20% Critical Rate | +8% damage when attacking targets inflicted with Abnormal Status |
| Marksman | Attack Speed +1 | 20% Critical Rate | 10% Boss Damage |
| Mercedes | 20% Boss Damage | 20% Critical Rate | +8% damage when attacking targets inflicted with Abnormal Status |
| Pathfinder | 20% Boss Damage | 20% Critical Rate | +8% damage when attacking targets inflicted with Abnormal Status |
| Wild Hunter | 20% Boss Damage | 20% Critical Rate | +8% damage when attacking targets inflicted with Abnormal Status |
| Wind Archer | 20% Boss Damage | 20% Critical Rate | +8% damage when attacking targets inflicted with Abnormal Status |
| Kain | 20% Boss Damage | 20% Critical Rate | +8% damage when attacking targets inflicted with Abnormal Status |
