## Chance Modifiers

{% columns %}
{% column width="50%" %}
All wild HA chance modifiers are applied **additively** to the base chance:

$$
\text{HA chance} = \frac{1 + \sum \text{boost}}{\text{base chance}}
$$

Example (55% boost with a 10% boost):

$$
\frac{1 + 0.55 + 0.1}{300}\Rightarrow \frac{1}{181.81} \approx 0.55%
$$

{% hint style="info" %}
When fully stacked, the maximum possible boost is currently **+105%**, resulting in **0.683%** chance per wild spawn
