Scaling Type:
Linear scaling (additive) for spike damage (+5 per copy)
Linear scaling for number of spikes (+2 per copy after the first one, capped at 40 spikes)
Detailed Explanation
Cactus activates whenever you take damage. When taking damage, the item fires a burst of spikes in a full 360° circle around the player. With 1 copy, you fire 3 spikes every time you take damage.
The damage of cactus scales with:
- Your Thorns stat
- Your number of Cactus copies
- The in-game damage multiplier
The damage formula can be explained as follows:
The spikes can deal crit damage and can also proc other items (with a proc coefficient of 0.5)
The damage of cactus scales with:
- Your Thorns stat
- Your number of Cactus copies
- The in-game damage multiplier
The damage formula can be explained as follows:
$$
\text{Spike Damage} = (\text{Thorns} + 5 \times \text{Cactus Copies}) \times \imagetooltip{Damage Multiplier}{https://res.cloudinary.com/dft1n3spr/image/upload/v1764501733/megabonk-guide/msyfbhopicnivvxuy6tk.png}
$$
The spikes can deal crit damage and can also proc other items (with a proc coefficient of 0.5)
How it Stacks
More copies of the cactus increase both damage and the number of spikes fired.
Each copy adds 2 additional spikes, and also increases the spike damage by +5 (mulitiplied by the damage multiplier as can be seen from the formula). The amount of spikes you can fire is capped at 40 spikes. (reached when you have 20 cacti)
This is what it looks like with 11 copies of the cactus
