The new floating castles act as meeting places for clans, and will contain exclusive skill-training areas for woodcutting, mining and other skills. Working on the clan's skill plots will add resources to upgrade the castle and pay for its upkeep, but may provide slightly less experience gain than traditional skill-training areas.
Customisable clan battlefields provide a sandbox map editor tool, letting clans design and build their own battlegrounds and minigames. Players will be able to design their own arenas and gameplay for the first time in RuneScape's ten year history, creating anything from capture the flag style matches and monster hunts to basic clan versus clan PvP battles. Perhaps the most exciting part of the feature is the ability for clan members to invite other players to try their games and challenge rival clans to competitive battleground matches. The expansion launches on 26th July.
