PvP Rewards need a change

Please look into the following changes

  • 50-100 umbral shards granted per an arena match (50 loss, 100 win)
  • a small chest with “rusher” or pvp gear. should have reduced count of items (1-2?)
  • a pvp vendor that salt can be used at. largely umbral shards should be bought here, 25 salt to 1 shard.
