Mechanics Explained You Need To Know In Honkai Star Rail! - DOT, Debuff & Break Effect

Here we’ll discuss how DOT is calculated for characters in Honkai Star Rail, Break Effect, and what’s the best situation for each element to use its debuff.

Now let’s talk about the characteristics of each element’s DOT and debuff. In Honkai Star Rail, each element has slightly different damage calculations and debuffs. This makes it fun to experiment with different DOT and damage effects on different enemies.

Two Types Of DOT & Four Element Debuffs

There are two types of DOT: Break DOT and Skill DOT. When an enemy has a Break Effect turned on, Break DOT is applied. DOT has four Element Debuffs, namely: Physical, Fire, Lightning, and Wind. Ice, Quantum, and Imaginary do not apply DOT to the enemy, but apply a debuff to the enemy.

Break Damage And Calculation For Each Element

When an enemy turns on this Break Effect, Break Damage will also hit it. This damage calculation is based on three factors:

  • Element Multiplier
  • Character Level
  • Target’s Maximum Toughness

As you can see, all elements have the same multiplier. It’s just that some elements have higher multipliers than others. Among them, the multiplier of Physical and Fire is 2, which is the highest. Wind has a multiplier of 1.5, Ice and Lightning have a multiplier of 1, and Quantum and Imaginary have a multiplier of 0.5.

Therefore, Physical damage and Fire damage have the highest onetime destruction damage, followed by Wind damage. Another thing you need to be aware of is that character level is actually the most important factor in this formula. The higher your level, the more destruction damage you get.

DOT Damage Calculation

So DOTs and debuffs are more interesting. Although DOT damage formula is a complex calculation, we only need to know how the base damage of each element is calculated. Because the rest of the effect is the same. So what we need to look at is the basic damage calculation and debuff effect of each element. Now let’s talk about each element.

Fire, Lightning, Wind DOT Damage

First off, Fire Burn, Wind Shear, and Lightning Flash are very similar. The level multiplier of Lightning Flash is 2x. Fire Burn has a level multiplier of 1x.

But Wind has a slight advantage. We calculate its level multiplier as: 1 x Stack Count x Level Multiplier. Because Wind element can have additional stacking layers. So when we fight elite enemies and bosses, it has up to 5 stacks of Wind Shear. So it’s a better DOT element for elite enemies and bosses.

Physical DOT Damage

Physical is another favorable factor for hurting bosses and elites. Because they calculated its base damage based on the enemy’s maximum health. So if we really try to increase this DOT damage of Physical Bleed, such as stacking Break Effect and DEF reduction, Bleed DOT damage may be 7%-16% of the boss’s health.

Quantum Debuff And Additional Debuff Damage

Besides Physical and Wind being good for boss fights, Quantum is another factor that can also be good for boss fights if applied properly. Although the multiplier of Quantum debuff is not high, its damage also depends on the enemy’s defense. So for elites and bosses, this can increase their damage.

Also, while Quantum Entanglement debuffs only have one stack and last only one turn, they can stack up to five stacks. Each time you attack an entangled enemy within a round, a layer will be stacked.

You may ask, what if I don’t have enough time to apply these five stacks? Don’t worry, another feature of Quantum Entanglement is the additional delay of enemy actions. This means that when you kill an enemy or Break Effect delays the enemy’s action, Quantum Entanglement will also delay its action additionally. Its calculation method is: 20% x (1+Break Effect).

In this way, the enemy needs more time to make the next move, and you have more chances to get extra Entanglement layers. Another benefit of Quantum Entanglement is because enemies take longer to recover from damage. So we have more chances to attack enemies in Break state and thus do more damage.

Imaginary Debuff

A similar concept applies to Imaginary Imprisonment debuffs. This debuff only lasts for one turn and has no DOT damage. This delays the enemy’s actions by 30% x (1+Break Effect).

This delay is longer than the additional delay introduced by Quantum Entanglement. Because Imprisonment not only increases the delay but also reduces the speed of the enemy by 10%. So the point of Imaginary Imprisonment is to delay the enemy’s turn, so that Break state lasts longer.

Plus, it helps extend the duration of debuffs we add to enemies, such as DEF Reduction. Therefore, Imaginary character does more damage indirectly. This debuff is especially useful for you if you have high damage Imaginary characters in your Honkai Star Rail Account.

Ice Debuff

Last but not least is Ice debuff. We calculate ice Freeze as 1x the level multiplier. Ice’s Break Damage is not high and is mainly used for freezing debuffs. When Freeze, the enemy cannot act this round, but after unfreezing, the enemy will move forward by 50% in the next round.

While this will make the debuffs on enemies wear off faster, it’s not a good option for debuffing raids. But when the enemy unfreezes, it will still be in Break state. This makes them last longer and we can deal with more damage.


That’s all about DOTs and debuffs for each element in Honkai Star Rail, along with how they work and damage calculations. Hope this guide can help you quickly increase your character’s damage output. See you in the game.
