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.
Make sure to have a IA preset with max meso + drop and another preset for max drop rate if you’re making a main. For boss mules make sure to have a seperate IA for max drop.
When To Work On Your Inner Ability
Inner Ability is much easier nowadays since they give away so much honor and the fact that you have 3 presets to use. You want to get meso/drop as soon as possible and then make a separate bossing IA when you start doing bosses like Chaos Root Abyss and up. Make sure to take advantage of Inner Ability events.
- 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 start doing bosses like CRA+, make your bossing IA
- If you’re making a main then you want to perfect your Training IA asap then your Bossing IA (wait for an IA event)
- If you’re making a bossing mule then you want to settle on Drop Rate IA and a Bossing IA
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, using Miracle Circulators to get to legendary is the most efficient if you have Mesos to spare.
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.

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 a really good skill since Critical Damage is one of the best damage multipliers in the game.
The Magician link skill can help 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 |
