Avoidability Fundamentals

How avoidability works in classic MapleStory, and how to maximize it for your character.

If you feel like monsters are “magnet-walking” into you or spells keep landing no matter how slippery you are, the problem isn’t your HP or potions. It’s Avoidability .


What Avoidability Does

Avoidability (EVA) affects your chance to dodge incoming attacks, not deal damage.

Specifically, it controls:

  • Touch damage misses (monsters bumping into you)

  • Magic damage dodges (certain spell-based hits)

  • How much extra room you have when positioning or tanking bosses

Avoidability does nothing to help you hit monsters. It only determines whether they hit you.


Two Separate Dodge Systems

Avoidability is not one mechanic. It feeds into two completely different formulas:

  • Touch damage dodge

  • Magic damage dodge

They scale very differently and behave very differently at high values.

Understanding this distinction clears up most EVA myths.


Level Adjustment (Very Important)

Before any dodge calculation happens, your avoidability is adjusted if you are lower level than the monster.

Level penalty formula

If your level is lower than the mob:

Adjusted Avoid = Avoid − (Monster Level − Your Level) ÷ 2

Notes:

  • This penalty only applies when you are underleveled

  • If the result goes below 0, it is treated as 0

  • This adjusted value is what the game uses next

If you are the same level or higher, no penalty applies.


Touch Damage Dodge (Physical Bumps)

This is the most common dodge scenario: monsters walking into you.

Exact formula

Touch Dodge Rate = Avoid ÷ (4.5 × Monster Accuracy)

Expressed as a percentage, then capped.

Dodge caps

ClassMinimumMaximum
Non-Thief2%80%
Thief5%95%

Even infinite avoidability will not exceed these caps.


What This Means in Practice

Touch dodge scales linearly.

Derivative:

Increase per EVA = 1 ÷ (4.5 × Monster Accuracy)

Boss example (≈250 Accuracy)

  • 1 Avoid ≈ 0.089% dodge

  • 60 Avoid (Stopper) ≈ +5.3% dodge

  • 100 Avoid (GM Bless) ≈ +8.9% dodge

This scaling stays consistent until you hit the cap.

Touch dodge is reliable, predictable, and scales well with buffs.


Magic Damage Dodge (Spells)

Magic dodge follows a completely different system.

It is non-linear, heavily threshold-based, and far less forgiving.

Simplified formula

Magic Dodge Rate = (10/9) − (Monster Accuracy ÷ (0.9 × Avoid))

If the result is ≤ 0 → no magic dodges occur


Critical Thresholds (Magic Dodge)

Magic dodge does nothing until you pass key avoidability thresholds.

ConditionResult
Avoid < Monster Accuracy0% dodge
Avoid = Monster AccuracyBarely dodging
Avoid ≈ 10× Monster AccuracyNear 100% dodge

This means:

  • If your avoid is below the mob’s accuracy, you will never dodge magic

  • Scaling improves rapidly once you cross that line

  • Gains slow down again at very high avoid


Why Magic Dodge Feels “Random”

Unlike touch dodge:

  • Magic dodge does not scale smoothly

  • Low-avoid characters see nothing

  • High-avoid characters suddenly feel invincible

Example outcomes:

  • ~500 Avoid vs Scarlion I → frequent dodges

  • ~750 Avoid vs Scarlion II → near immunity

  • Zakum / Horntail with max EVA → ~83% magic dodge

This matches observed boss behavior very closely.

Practical Takeaways

  • Touch dodge always benefits from more avoid

  • Magic dodge only matters if you stack a lot of avoid

  • EVA buffs are extremely strong for bosses with ~250 ACC

  • Thieves benefit disproportionately due to higher caps

  • If magic is killing you and your EVA < mob ACC, EVA won’t save you


Final Rule of Thumb

  • If you’re dodging bumps → EVA is working

  • If you’re not dodging magic → check the accuracy threshold

  • EVA is strongest when paired with levels + buffs

  • Touch dodge is incremental; magic dodge is all-or-nothing

Avoidability isn’t luck. It’s math with sharp breakpoints.

Once you know where those breakpoints are, EVA becomes one of the most powerful defensive stats in the game.
