A 50ft-by-50ft stone temple for the relatively  unknown deity Protegas that provides protection to those who seek it.  The room is lit by torches that provide ample light. There is a fountain  in one of the walls that provides a water source for moves like Surf.  The arena is set indoors so weather moves, SolarBeam and Thunder cannot  be used. Despite being ancient, the temple still has a relatively strong  structure that allows seismic moves like Earthquake, Bulldoze and  Magnitude to be used up to 3 times in total (not 3 times each though).  The floor can be dug through as well but, because it is made of stone,  the energy cost for Dig is increased by 2 for pokemon that aren't rock-  or ground-type. Over the centuries, some plant life has broken through  the floor, allowing non-grass-types to use moves like Grass Knot.
At the beginning of every round, Protegas will protect any pokemon he  feels is being ganged up on. A pokemon is considered to be ganged up on  if it is targeted by:
- At least four enemy single-target moves
 
- Three enemy single-target moves and at least two enemy multi-target moves
 
- Two enemy single-target moves and four enemy multi-target moves
 
- Six enemy moves, whether they are single-target, multi-target or a combination of the two
 
Note:  this is done by the commands issued and stuff like Encore and Disable  changing a pokemon's moves will not affect this, but substitutions will.  Substitutions cannot be made based on whether or not an opponent's  pokemon gets the barrier.
Any pokemon that meets any of those criteria will be given a protective  barrier for that round. The barrier is treated as a 20 HP typeless  pokemon with the same rank defences as the pokemon it is protecting. The  barrier protects the pokemon from all effects of enemy attacks and will  disappear once it runs out of HP, is hit by two enemy non-damaging  moves or at the end of the round, whichever comes first. The barrier  will not protect from any spillover damage (so an attack that does 25  damage will destroy the barrier and do 5 damage to the target). The  barrier will not protect a pokemon from allied attacks that hit it, nor  will it be affected by allied attacks. A last pokemon standing will  always receive Protegas' barrier at the start of a round except in a 1v1  matchup.
