+/// <summary>
+/// This move reduces damage from physical and special moves for five turns. This can be used only in a hailstorm. 
+/// </summary>
+/// <remarks>
+/// Aurora Veil reduces the damage done to the user by physical and special moves for five turns by half; in battles
+/// beside Single Battles, Aurora Veil protects the user and all allies, but only reduces damage by (roughly) a third
+/// rather than half (specifically, with a multiplier of 2732/4096). It does not reduce damage done by self-inflicted
+/// confusion damage, critical hits, or moves that deal direct damage. Aurora Veil can only be used during hail or snow,
+/// but the effect remains even after hail or snow ends; Cloud Nine and Air Lock will cause Aurora Veil to fail even if
+/// it is hailing or snowing.
+/// <br/>
+/// While it can be active at the same time as Reflect and Light Screen, the damage reduction effects do not stack.
+/// Aurora Veil is removed from a Pokémon's side of the field if it is hit by Brick Break, Defog, Psychic Fangs, or
+/// Raging Bull, or if a Pokémon with Screen Cleaner is sent out. Pokémon with the Ability Infiltrator ignore the effects
+/// of Aurora Veil when attacking.
+/// <br/>
+/// If a Light Clay is held when Aurora Veil is used, it will extend the duration of Aurora Veil from 5 to 8 turns. 
+/// </remarks>
