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. Although the  arena is set indoors, the roof is ruined enough to allow weather moves  to work. Despite being ancient, the temple still has a relatively strong  structure that allows seismic moves like Earthquake to be used. The  floor can be dug through as well and, 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 or one damage deaing combinations
- 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. In battles with more than one  active pokemon per team, a last pokemon standing will always receive  Protegas' barrier at the start of a round unless every team is down to  its last pokemon.
