Demonic Blade

Demonic Blade

Rare
Crits have a +25% chance to heal you.
Scaling Type:
Linear scaling (additive) for heal factor (+0.25 per copy) Fixed +1% crit chance (first copy only)

Detailed Explanation

Whenever you land a critical hit, Demonic Blade gives you a chance to heal.
The chance scales linearly with the number of copies:
 
 
$$ HealFactor(n) = 0.25n \times ProcCoefficient $$
 
 
Where
- $ n $ = number of Demonic Blade copies
- ProcCoefficient = the proc coefficient of the attack that crit. For normal weapon attacks this is 1. Other items that can proc items like these (such as holy book) has a ProcCoefficient of 0.5
 
This value determines how much HP you heal per crit. The proc coefficient of the attack that crit affects the healing amount - if an attack that procs this item has a proc coefficient of 0.5, you'll heal half as much.
 

How healing behaves

The game converts the HealFactor into actual healing like this:
 
- If HealFactor < 1 → sometimes heal 1 HP
- If HealFactor ≥ 1 → guaranteed to heal at least 1 HP
- At higher values → can heal 2, 3, or more HP per crit
 
Examples (with ProcCoefficient = 1):
 
 
CopiesHealFactorResulting Healing
10.2525% chance to heal 1 HP
20.5050% chance to heal 1 HP
30.7575% chance to heal 1 HP
41.00Always heal 1 HP
61.5050% heal 1 HP, 50% heal 2 HP
82.00Always heal 2 HP
The first copy of crit blade gives you a +1% crit chance.

How it Stacks

Demonic Blade has one scaling stat:
 

1. Heal Amount (Linear Scaling)

 
Each copy adds +0.25 to the base heal chance:
 
 
$$ \text{BaseHealChance}(n) = 0.25n $$
 
 
This is then multiplied by the proc coefficient of the attack that crit:
 
 
$$ \text{EffectiveHealChance}(n) = 0.25n \times \text{ProcCoefficient} $$
 
 
The EffectiveHealChance determines how much HP you heal:
- If < 1 → chance to heal 1 HP (equal to the decimal part)
- If ≥ 1 → guaranteed to heal at least floor(EffectiveHealChance) HP
- May heal 1 additional HP based on the decimal part

2. Crit Chance Bonus (Fixed)

 
The +1% crit chance is fixed and does not increase with more copies.
