All Pokemon in the user's party receive 1/2 damage from Special attacks for 5 turns. Light Screen will be removed from the user's field if an opponent's Pokemon uses Brick Break. In double battles, both Pokemon are shielded, but damage protection is reduced from 1/2 to 1/3.
Restores a fraction of the user's max HP depending on the weather: 2/3 during Sunny Day, 1/2 during regular weather and 1/4 during Rain Dance, Hail and Sandstorm.
Almost always goes last; in trainer battles, the target is switched out for a random member of its team. Escapes from wild battles. Has no effect if the target has Suction Cups or used Ingrain.

Notes: If it could double Powder, it would be almost usable because of the Special Attack. As it is, it doesn't learn enough Special attacks to build a whole set, and after factoring in nature, Choice Band and STAB, it'll do more damage with Physical attacks. Use Adamant with the physical HPs and Naughty with HP Fire. Really, good luck with this thing. Butterfree outclasses Beautifly at everything and nobody even uses that.

Shield Dust: If the opponent uses a move that has secondary effects that affect this Pokemon in addition to damage, the move's secondary effects will not trigger. (For example, an Ice Beam will lose its 10% chance to freeze this Pokemon.)

Notes: It's better than Beautifly, but, then again, so is Delibird. Dustox can take a Special hit or two, but it's not like it's going to deal any damage in return. So basically, use Dustox for stalling with Moonlight and the pseudos: -hazing (Whirlwind) and -passing (Light Screen). Also, have somebody with Spikes on your team, or else Whirlwind is fairly useless. Sludge Bomb gets STAB and might Poison, and that's about all Dustox can hope to do.
