New status conditions and weather.

Frostbite: the same as burn, but it lowers Sp. Attack instead
Drowsy: the Pokemon may fail to act, also takes more damage from attacks
Obscured: increased evasion
Primed: attacks deal more damage
Fixated: the Pokmon is fixated on the last move it used. This move will deal increased damage while the fixation lasts, but any damage dealt to the fixated Pokmon is also increased.

Snow: Attacks are more likely to inflict frostbite, drowsy Pokemon are more likely to fail to act, Ice Pokemon have boosted Speed

Also strong sun boosts Speed of Grass types. Fog is back and works the same as always.

Jagged splinters is a new field effect, where Pokemon take damage at the end of each turn. Stealth Rock and other moves now have this effect.
