EVs: 252 HP / 6 Def / 252 SDef
Great 'defensive' Pokémon right here. As the held item slows the target by 50% and makes Flying/Levitate users susceptible to ground attacks, it's incredible when paired with a sweeper like Landorus/Garchomp.
WoW is to cripple physical attackers - it halves their attack, which is why the spread is SDef orientated instead. Taunt stops walls etc in their tracks and combined with WoW/recover, you can actually burn stall them to death.
