Potion, please help.

Im trying to create a Potion of Fire Resistance that does exactly what the name implies. Would anyone know how I can do this. Any help would be appreciated.

Make a state called "Fire Resistance" in the database. Under the features, go to rate, element rate, Fire, and then set it to, say, 50%. (EDIT: You can set it to what ever you want, but be careful of the percentages. 100% means normal damage, 200% is double damage, 50% is half damage, etc. If you set it to a negative number, such as -100%, then that element will be absorbed. So, if normal fireball damage would be 500hp, and you had a "fire absorb" skill that set fire's element rate to -100%, you would gain 500hp upon being hit with fireball. Make sense?)

Now, go create your potion as an item. Under effects, use "add state" to add your Fire Resistance state. Set the probability to 100%, and there you go.

Yeah, that makes sense. But do I leave the Removal Conditions and Messages sections blank or what?

You can set them however you want. I'd imagine you'd want the potion to wear off eventually, though. So, maybe set the removal conditions to 10 turns or 100 steps? If you want the potion to only work in battle, put a check in the "Remove at Battle End" box of the state, and make the item only useable in battle.

As for the messages, again, just have it say what you want. The first one is the message that appears when one of your dudes has the state applied to them. So, something like "resists fire!" would work. The second one is for the enemy, same deal. The third one is for when the state is still there at the end of a turn. So, "still resists fire!" or something. (Basically, it's to make sure the player knows the state hasn't worn off yet) The last one is the message it gives when the state wears off. So you can put something like, "no longer resists fire."
