New spell for pvp

Create a new spell that will reduce pa/ma/dr/mr by 50% or to a minimum reasonable number, like a set with dr 60 items or something. If the player has lower armors than dr 60, then it has no effect on his defences. 

While spell is active player cannot be amped/ds-d. 

Spell duaration: 20sec (enough time so a player can escape or be killed) 

Int req: 59? 

This spell will create a chance for newer players to play against old players with very good gear. Players still need skill to time the enemy and kill them but its actually possible to take down an abaddon. Players with gear will still have their edge since the duaration is only 20 seconds and with invi pots its easy to escape.
