A Breakout Discussion Thread is an offshoot of the Feedback & Game Issues thread where specific discussion and proposals are made. This discussion will seek to codify which moves will be covered by Arena restrictions. Existing common examples: No Water Source available for Surf. Ground is too soft or sturdy (or non-existant) to a;low Seismic Attacks (Earthquake/Magnitude/Bulldoze [Sometimes Earth Power in the last case]). No Grass available for Grass Knot. It is naturally true that Arenas can be built with whatever effects the user likes, however we're trying to go for natural physics here. What seems to be most at issue is attacks that call on natural elements. The targets of most of these restrictions generally have wide distribution via TM or Tutor, so they will be the targets of this discussion topic. While for consistency's sake a rarer move might be subject to a common sense restriction, we should stick to attacks with high levels of distribution. It is assumed that some of these restrictions will only apply to Pokemon not of that type, since Pokemon of that type can usually generate the element in question. The question at issue seems to be about Rock attacks. Specifically, Rock Slide and Rock Tomb, which are very common attacks on non-Rock type Pokemon. I'm curious to see if there are any other attacks you think should be covered before making a final proposal. To be clear, here is the current list of attacks that fall under a common restriction: Surf/Dive - No Water Source. This list could technically include Sludge Wave (all other Pokemon) and Muddy Water (all opponents). Earthquake/Bulldoze/Magnitude - No Seismic Activity Grass Knot - No Grass in Arena. Adding a restriction for Rock Slide/Rock Tomb under "No Rock in Arena" could be implemented. I do not think Stone Edge should be covered, however, since it's distribution, while wide, is much smaller, and it basically keeps to Rock, Ground, and Fighting types exclusively. Thoughts, opinions, and discussion welcome.
