Skill Decals

Skill Decals can be obtained from the Mushroom Club in the Waiting Room or are awarded as a Prize.

Decals can be equipped for various bonuses by visiting the Mushroom Club, and the number that can be equipped increases as the grade of your Fighters increase.

Equipped Decals are lost if you die in the Tower (but are not lost if you salvage your fighter), or peel them from your Fighters.

Purchasing Mushroom Stew gives a random Premium Skill Decal. These decals are not lost when peeling them off of your characters and will be gotten back upon killing your character if you died with them on.

Premium Decals can be exchanged for Recycle Points in the Hernia at the following rates:

 ★★★★★ |  100000

## Death Metal Stew

You can use  10 to receive a random ★★★ or higher decal from the Death Metal Stew. Occasionally, the Mushroom Magistrate will host events limiting the decals that can be obtained in this stew to limited or popular ones. Check the lineup to see what's available!

## Stacking Decals

When a Skill Decal has a Premium and non-Premium version, both can be applied to a Fighter (with sufficient Skill Decal slots), in many cases giving the user the effect of the Decal twice. There are however notable exceptions, where even stacking non-identical decals do not stack as the user might expect, such exceptions primarily include decals with stated limits.

As an example, the decal Serial Killer, increases attack by 10% for each consecutive kill without taking damage, and that increases to 20% when stacking it with the Premium version, however the limitation of up to 100% increased damage remains the same.

## Additive and Multiplicative decal pairings (still a work in progress)

Decals grouped together are additive with each other. Decals from different groups are multiplicative with each other. Using decals that are additive with each other results in diminishing returns so it is typically better to use decals that are multiplicative to achieve higher damage. For example, Serial Killer gives a 100% attack increase which is x2 base attack on its own (100 + 100 = 200) but if you then add Golden Gym, Golden Gym is only a 15% increase to your previous Attack value (100 + 100 + 30 = 230). However, if you were to use Professional Cosplayer you would end up with more attack despite it displaying a lower number (100 + 100 = 200 x 1.2 = 240). Maximizing your damage potential is very important for climbing at high floors (F200+).

Notes:

- Decals in the base attack group are better to stack until around +100% attack since they affect your attack value rather than your damage value. Adding +100% attack is more than a x2 damage multiplier as your enemies do not magically gain more defense. However, stacking base attack beyond 100% does seem to suffer from diminishing returns like everything else. Probably some damage calc nonsense we don't understand yet.

- Superalloy Death ZAM's 2 damage bonuses are multiplicative with each other. It's an excellent decal.

- Warrior Monk & Violence Class are strong enough that it's still worth it to run them together in pretty much any circumstance if you want to.

- Rio Bravo's Explosive bullet damage bonus is multiplicative with it's own Pierce damage bonus. Also, explosive bullets cannot headshot and deal massive self damage if you are too close.

- Niten Ichi-ryu is powerful but often not worth the loss of versatility created by being forced to use 2 of the same weapon rather than 2 weapons that complement each other.
