What are those letters for in the damage buttons

[Hydrohead]

I am about to start my first StarFinder game and I am seeing Capital Letters in some of the damage buttons on the Actions Tab.
The button will say something like 1d4 P.
It seems to role just fine in the chat window though.
I can not find an explanation for these letters.
Did I get something wrong?
Is there a reason for these letters?
If so, what do they mean and how do I find out?

Thanks!

This is the forum for starfinder society games, your question is better suited for the normal starfinder forum.

Anyways, they represent the damage types:


ENERGY DAMAGE
The following types of damage are energy damage. Other, rare forms of energy damage exist, and such weapons specify whether they target EAC in their descriptions.

Acid (A): Damage dealt by corrosive substances and effects.

Cold (C): Damage dealt by ice and cryogenic energy.

Electricity (E): Damage dealt by lightning and other electric shocks.

Fire (F): Damage dealt by flames, lasers, and extreme heat.

Sonic (So): Damage dealt by loud noise or damaging frequencies.

KINETIC DAMAGE
The following are types of kinetic damage.

Bludgeoning (B): Damage from blunt force.

Piercing (P): Damage from spikes, bullets, and punctures.

Slashing (S): Damage from blades, claws, and sharp edges.

From the main forums pages look in the "Game Systems" section. It's right down the bottom (3rd from the bottom).
