-PHASE 4 AUGUST 17. If you were in phase 3 you start on 16th. Early access is August 24th. Remember to sleep. Moogles will deliver in-game items to us. Cap is at 20 in phase 4 because it's more a demo version of the game. Full voice acting like release version. Game data will be transferred from phase 4 -> early access/release. Only if there is a critical bug will all data be deleted. Yoshi wants players to test graphic stress in housing areas. You can change the roof, walls, etc which will cause a lot of stress. Limsa Lominsa housing will be open to explore and jump around on but can't go inside. PVP also available: Colisseum and Front Line has been in preparations. "Wolves Jail" (?) is something for Grand Company. Yoshi wants players to hit each other so devs can check the distance that players can hit from. No PVP-specific actions yet, those will be in release version.
