Scaling Type:
Linear scaling for thorns bonus and explosion radius (capped at 10.0)
Fixed 50% proc chance
Fixed 50% explosion damage multiplier
Detailed Explanation
Quin's Mask gives your thorns damage a chance to create an explosion. However besides triggering when dealing Thorns damage both the Cactus and Aegis can also trigger this item.
Whenever you deal thorns damage (or damage through Cactus, or Aegis), there's a 50% chance to trigger an explosion at that enemy's position.
The explosion:
- Damages all enemies within a radius around the hit enemy
- Deals 50% of the original damage to each enemy hit. If thorns deals 20 damage, the explosion damage will be 10 if thorns procced it. If your cactus deals 25 dmg on hit and the explosion procced from the cactus it will deal 50% of 25 (12.5 but rounded up to 13)
- The explosion radius scales with both your number of Quin's Mask copies and your size stat
Explosion radius formula:
Where
- $ n $ = number of Quin's Mask copies
- $ S $ = your size stat multiplier
- Radius is clamped between 1.0 (minimum) and 10.0 (maximum)
Thorns bonus:
Each copy of Quin's Mask also gives you +20 Thorns stat. This increases your thorns damage, which in turn increases the explosion damage (since explosion deals 50% of thorns damage).
Damage sources that can trigger the explosion:
- Standard thorns damage (from enemies attacking you)
- Cactus spikes
- Aegis shield damage

Explosion radius formula:
$$
\text{Radius}(n, S) = \min\left(\max\left((5 + n) \times S,\ 1.0\right),\ 10.0\right)
$$
Where
- $ n $ = number of Quin's Mask copies
- $ S $ = your size stat multiplier
- Radius is clamped between 1.0 (minimum) and 10.0 (maximum)
Note on size stat
Do note that it only calculates the explosion radius when you pick up a new quins mask or if your amount of quin mask changes (like losing one through microwaving it). The radius does not change if you increase your size after picking it up, until you change the amount of quins mask you haveThorns bonus:
Each copy of Quin's Mask also gives you +20 Thorns stat. This increases your thorns damage, which in turn increases the explosion damage (since explosion deals 50% of thorns damage).
Damage sources that can trigger the explosion:

- Cactus spikes
- Aegis shield damage
How it Stacks
Quin's Mask has multiple scaling stats:
The explosion chance is always 50% and does not scale with copies. Each thorns damage instance has a 50% chance to explode, regardless of how many masks you have.
Each copy gives you +20 Thorns stat:
This increases your base thorns damage, which indirectly increases explosion damage since explosions deal 50% of the original thorns damage.
The explosion radius scales with both copies and your size stat:
Where
- $ n $ = number of Quin's Mask copies
- $ S $ = your size stat multiplier
Radius limits:
- Minimum radius: 1.0 (even if calculation is lower)
- Maximum radius: 10.0 (even if calculation is higher)
Examples at different sizes:
The explosion damage multiplier (50%) does not change with copies. However, since each copy adds +20 Thorns, your thorns damage increases, which means the explosion damage also increases indirectly.
Example:
- With 100 base Thorns and 1 mask: Thorns = 120 → Explosion = 60 damage
- With 100 base Thorns and 3 masks: Thorns = 160 → Explosion = 80 damage
1. Proc Chance (Fixed)
The explosion chance is always 50% and does not scale with copies. Each thorns damage instance has a 50% chance to explode, regardless of how many masks you have.
2. Thorns Bonus (Linear Scaling)
Each copy gives you +20 Thorns stat:
$$
\text{ThornsBonus}(n) = 20n
$$
This increases your base thorns damage, which indirectly increases explosion damage since explosions deal 50% of the original thorns damage.
3. Explosion Radius (Size-Dependent Linear Scaling)
The explosion radius scales with both copies and your size stat:
$$
\text{Radius}(n, S) = (5 + n) \times S
$$
Where
- $ n $ = number of Quin's Mask copies
- $ S $ = your size stat multiplier
Radius limits:
- Minimum radius: 1.0 (even if calculation is lower)
- Maximum radius: 10.0 (even if calculation is higher)
Examples at different sizes:
Size stat is calculated on pickup as explained under "detailed explanation"
4. Explosion Damage (Indirect Scaling)
The explosion damage multiplier (50%) does not change with copies. However, since each copy adds +20 Thorns, your thorns damage increases, which means the explosion damage also increases indirectly.
Example:
- With 100 base Thorns and 1 mask: Thorns = 120 → Explosion = 60 damage
- With 100 base Thorns and 3 masks: Thorns = 160 → Explosion = 80 damage
