Resistances tooltips (the things that pop up when you click on the icons - nice addition, by the way!):
Fire:
Currently reads "This icon represents the resistance against Fire attacks. The higher the value, the less damage will take. For the elemental and physical conditions (Burning, Weakened, etc) will influence the chances and the duration of the damage over time debuffs."
Could change to: "Resistance against Fire attacks. The higher the value, the less damage will be taken. Also lowers the chance to receive Burning and Weakened, and reduces the duration of fire-based damage over time debuffs."
1. "This icon represents" is unnecessary because it's implied by being a tooltip and the less text you have, the better. We want to spend our time reading the story, not the manual.

2. "Will take" was missing a subject and you really don't want to use "he/she" if you can avoid it. I actually don't like the second sentence at all, but I'm not 100% sure you can just cut it.
3. The third sentence was a bit awkward and a little misleading. I am assuming Fire resistance only affects Burning and Weakened, and Burning and Weakened should probably show up in yellow text like Fire does.
4. I forgot what resistance does now. Does it actually reduce the duration of debuffs still or just the damage on them?
Burning:
Currently reads "This icon represents the resistance against Burning attacks. The higher the value, the less damage will take. For the elemental and physical conditions (Burning, Weakened, etc) will influence the chances and the duration of the damage over time debuffs."
Umm...is that what it does? Does it help against Weakened or just Burning?
If not, I'd suggest: "Resistance against Burning attacks. The higher the value, the less damage will be taken. Also reduces the chance to receive and the duration of Burning."
The first and third sentences seem redundant, but I need to think on them more.
Weakened:
Currently reads "This icon represents the resistance against Weakened attacks. The higher the value, the less damage will take. For the elemental and physical conditions (Burning, Weakened, etc) will influence the chances and the duration of the damage over time debuffs."
Same comments as Burning. "Resistance against Weakened attacks. The higher the value, the less damage will be taken. Also reduces the chance to receive and the duration of Weakened."
Water:
Currently reads "This icon represents the resistance against Water attacks. The higher the value, the less damage will take. For the elemental and physical conditions (Burning, Weakened, etc) will influence the chances and the duration of the damage over time debuffs."
Something tells me you copied and pasted these...
"Resistance against Water attacks. The higher the value, the less damage will be taken. Also lowers the chance to receive Frozen and Scared, and reduces the duration of water-based damage over time debuffs."
Frozen, Scared, Tired, Slowed, Shattered, Confused, Poisoned, and Paralyzed should also follow the same pattern as Burning.
Air:
Change to "Resistance against Air attacks. The higher the value, the less damage will be taken. Also lowers the chance to receive Tired and Slowed, and reduces the duration of air-based damage over time debuffs."
Earth:
Change to "Resistance against Earth attacks. The higher the value, the less damage will be taken. Also lowers the chance to receive Shattered and Confused, and reduces the duration of earth-based damage over time debuffs."
Dark:
Change to "Resistance against Dark attacks. The higher the value, the less damage will be taken. Also lowers the chance to receive Poisoned and Paralyzed, and reduces the duration of dark-based damage over time debuffs."
Wait, does Dark resistance actually help against Paralyzed? I don't remember. Also, it's too late now, but might sound cooler if this was "Shadow" instead of "Dark".
