Should You Pull for Arlan?

Main DPS

Arlan is a Lightning damage dealer who mostly hits one target at a time. He pays for his Skill with his own HP instead of Skill Points, and the more HP he is missing, the harder he hits. With proper investment his damage is not bad, but you have to keep his HP low and keep him alive at the same time, which is a real hassle. If you have other characters to build, put your resources into them first.

A fit if you already own a strong shielder like Aventurine, Gepard or Dan Heng • Permansor Terrae and want to try a playstyle that trades HP for damage. If you are short on resources, skip Arlan.

Memory of Chaos Weak You have to bring a shielder so Arlan can survive at low HP, and every extra defensive unit you add lowers the team's damage.
Pure Fiction Weak Arlan mostly hits a single target, and in battle only his Ultimate spreads damage to adjacent enemies.
Apocalyptic Shadow Weak His ability multipliers are low and you have to manage his HP the whole time, so he struggles to keep up with other damage dealers.
Pros & Cons

Pros

  • Deals damage without spending Skill Points

Cons

  • The lowest base DEF in the game, genuinely paper thin
  • Cannot heal himself the way Blade can
  • Absolutely needs shields to survive and to keep his HP at the level that is optimal for damage
  • Not a character worth investing in

Best Arlan Build Guide

Best Arlan Build

Build Arlan like a regular CRIT damage dealer. Focus on ATK, CRIT Rate and CRIT DMG, and only get SPD up to the breakpoint you are aiming for.

Best Light Cones

  • 1 On the Fall of an Aeon On the Fall of an Aeon Great
    Stacks ATK, reaching 64% ATK at the full 4 stacks on its highest Superimposition, and it also boosts his DMG when Arlan inflicts Weakness Break. It is at its best when you can keep the full stacks for the whole fight, and its damage drops in fights where that is hard to do.
  • 2 Something Irreplaceable Something Irreplaceable Great
    Raises his ATK and boosts his DMG when Arlan defeats an enemy or gets hit. A great 5-star pick if you already have it.
  • 3 The Unreachable Side The Unreachable Side Great
    Gives CRIT Rate and Max HP, and Arlan deals more DMG each time he gets attacked.
  • 4 A Secret Vow A Secret Vow Good
    A 4-star Light Cone that raises his DMG and lets him deal extra DMG to enemies whose current HP percentage is equal to or higher than Arlan's. That effect suits his low-HP playstyle.
  • 5 Ninja Record: Sound Hunt Ninja Record: Sound Hunt Good
    Raises his HP and gives CRIT DMG whenever Arlan heals or loses HP, which fits how he spends his own HP.

Best Relics

1
His best set. It gives CRIT Rate and boosts both Skill and Ultimate DMG, which are exactly Arlan's two main sources of damage.
2
The second choice, giving Lightning DMG Boost and ATK.
3
The third choice. Arlan gets bonus CRIT Rate just by using his Skill. The HP from this set mostly just helps him survive a bit longer.

Best Planar Ornaments

1
One of his two top picks. Arlan needs at least 135 SPD to activate its effect, and it gets even better if you push him to 160 SPD through relic stats and SPD buffs.
2
On par with Glamoth. It gives CRIT Rate and boosts Skill DMG, but it needs 70% CRIT Rate.
3
Gives CRIT Rate and boosts Ultimate DMG, and only needs Arlan to have 50% CRIT Rate or more.

Main Stats

  • BodyCRIT Rate or CRIT DMG
  • FeetSPD or ATK%
  • Planar SphereLightning DMG Boost
  • Link RopeATK%

Substats

  • 1CRIT Rate
  • 2CRIT DMG
  • 3SPD (up to your chosen breakpoint)
  • 4ATK%

CRIT Rate or CRIT DMG on the Body both work. Go SPD on the Feet first, especially if you use Glamoth, though ATK% is fine too. Use Lightning DMG Boost on the Planar Sphere and ATK% on the Link Rope.

SPD only needs to reach the breakpoint you are aiming for, then put everything else into CRIT. Try to have 2% CRIT DMG for every 1% CRIT Rate.

Stat Targets

  • CRIT Rate60% or more
  • CRIT DMG120% or more
  • ATK2500 or more
  • SPD135 or more if you use Glamoth
  • HP3100 or more
  • DEF800 or more

Skill Priority

Ultimate = Talent = Skill > Basic ATK

His Ultimate is his biggest source of damage, his Talent boosts his DMG based on how much HP he has lost, and his Skill is his damage source while the Ultimate is not ready. Level all three early, in any order. Basic ATK comes last.

Trace Priority

Revival > Repel > Endurance

Revival is the only healing in Arlan's kit, so unlock it first. Repel lets him nullify all DMG except DoT until he is attacked, as long as he enters battle with 50% HP or less. Endurance only raises his chance to resist DoT debuffs, so it can wait.

Eidolon Priority

E6 is the most valuable

E6 Self-Sacrifice: when his HP is at 50% or below, his Ultimate deals 20% more DMG and the DMG multiplier on adjacent targets is raised to match the primary target, turning his Ultimate into a very strong spread attack. E2 Breaking Free removes 1 debuff from Arlan every time he uses his Skill or Ultimate, which is fairly useful. E3 and E5 raise his skill levels.

Best Arlan Teams

Budget Team (All 4-Stars)

Replace Yukong with: Pela Replace Trailblazer (Preservation) with: Lynx

Arlan likes a team with two Supports and one Shielder. Yukong raises his CRIT stats and Asta raises his SPD. Trailblazer (Preservation) taunts enemies so they don't go after Arlan while his HP is low. Without Trailblazer (Preservation), Lynx gives him a good chunk of healing to keep him alive.

Arlan Hypercarry Team

Replace Bronya with: Ruan Mei, Welt Replace Tingyun with: Asta, Pela Replace Aventurine with: Dan Heng • Permansor Terrae, Gepard, Fu Xuan

The whole team stacks buffs on Arlan while he uses his Skill to trade HP for damage. Arlan doesn't spend Skill Points, so Bronya can use as many as she wants. Aventurine keeps Shields up so Arlan doesn't go down at low HP. Keep in mind that the faster Arlan acts, especially when Bronya advances his action, the faster he burns through Shields, so your shielder has to be fast enough to reapply them in time.

Best Teammates for Arlan

Dan Heng • Permansor Terrae
Dan Heng • Permansor Terrae

His Shields are among the biggest in the game, with better uptime than Gepard's, and he buffs Arlan's damage even more than Aventurine does.

Aventurine
Aventurine

Big Shields with better uptime than Gepard's, and he also boosts Arlan's damage.

Gepard
Gepard

Creates Shields with his Ultimate and can Freeze an enemy with his Skill, which takes care of Arlan's survival problem.

Lynx
Lynx

Gives Arlan a good chunk of healing so he doesn't go down, and can stand in for a shielder.

Sunday
Sunday

A hypercarry support who works with almost every damage dealer, Arlan included.

Sparkle
Sparkle

Arlan's Skill doesn't use Skill Points, so Sparkle can spend them freely without leaving the team short.

Bronya
Bronya

Also benefits from Arlan not spending Skill Points. The catch is that frequent action advances make Arlan burn through Shields faster, so your shielder has to keep up.

Yukong
Yukong

A 4-star who raises Arlan's CRIT stats, a good fit for budget teams.

Asta
Asta

Raises the whole team's SPD and gives Arlan extra ATK.

Pela
Pela

Lowers enemy DEF and strips their buffs, so Arlan hits harder.

How to Play Arlan

Trade HP for Damage

His Skill, Shackle Breaker, costs 15% of Arlan's Max HP instead of a Skill Point. If he doesn't have enough HP, his HP drops to 1, and at 1 HP you can keep using his Skill with no further cost. His Talent, Pain and Anger, increases his DMG for every percent of HP he is missing, up to 72% more DMG. That is why Arlan wants to stay at low HP for as long as possible.

Keeping Arlan Alive Comes First

At low HP, even a light hit can knock Arlan down, so your team almost has to include a shielder with big Shields. His Skill costs a percentage of his Max HP, so extra HP only makes him burn through it faster, while DEF is what actually helps him take hits. His Trace Revival restores 20% of his Max HP when Arlan defeats an enemy at 30% HP or lower, so if you need a quick heal, finish off an enemy that is easy to knock out.

Ultimate That Hits Adjacent Enemies

His Ultimate, Frenzied Punishment, only costs 110 Energy and at level 10 deals Lightning DMG equal to 320% of his ATK to the main target and 160% to adjacent enemies. Use it when enemies are lined up, especially if they are weak to Lightning or already Weakness Broken. With E6, when his HP is at 50% or below, adjacent targets take the same DMG multiplier as the main target.

Technique and Repel

His Technique, Swift Harvest, attacks the enemy immediately, and after entering battle deals Lightning DMG equal to 80% of his ATK to all enemies. It doesn't cost any HP. His Trace Repel lets Arlan nullify all DMG except DoT if he enters battle with 50% HP or less, and the effect goes away after he is attacked.

Arlan FAQ

Is Arlan worth investing in?
He shouldn't be a priority. Arlan's damage is lackluster compared to other damage dealers, and he needs too much support to work. Unless you really have nobody else to build, spend your resources on other characters.
Does Arlan use Skill Points?
No. Arlan's Skill costs 15% of his Max HP instead of a Skill Point, so teammates like Sparkle or Bronya can use all the Skill Points.
Does Arlan really need a shielder?
Pretty much. Arlan wants to stay at low HP so his Talent boosts his damage, and at low HP he goes down very easily. Aventurine, Gepard and Dan Heng • Permansor Terrae are all good choices, and a budget team can use Trailblazer (Preservation).
What Light Cone should Arlan use?
On the Fall of an Aeon, Something Irreplaceable and The Unreachable Side all suit him very well. For a 4-star option, A Secret Vow is a solid pick.
Which Eidolon should I aim for on Arlan?
E6 is the most valuable: when his HP is at 50% or below, his Ultimate deals 20% more DMG and hits adjacent targets as hard as the main target.
