These Patch Notes were announced on 20 February 2014.
  • In celebration of Old School RuneScape's 1st anniversary, the city of Prifddinas has been opened for a mammoth party, with gifts.
  • Ava's devices now have a 'Commune' option. This allows you to commune with your undead chicken, so you can ask it to stop gathering random metal junk while you've got it equipped.
  • Left-clicking on your cannon will now let you reload it, even if it isn't currently firing.
  • The middle mouse-button can now be used to rotate the game camera. For players who'd prefer to use that button for clicking instead, there's a new button on the Options menu to restore the previous behaviour. The volume controls have moved to a separate Audio Options panel to accommodate this.
  • The Slayer helm (i) and all versions of the black mask (i) now offer a 15% damage boost to Magic damage against your assigned Slayer target, like they already do for melee and Ranging.
  • The Slayer helm (i) now has a +3 mage attack bonus, a +3 range attack bonus and a +10 mage defence bonus.
  • Players no longer need to wait 30 seconds when world-hopping.
  • The combat stance system has been overhauled to make players less likely to get put in a Defensive stance unexpectedly when switching weapons or autocasting spells.
  • The granite maul no longer performs its special attack against the wrong target or through walls.
  • The Valentine's Day event has closed, and its items have been removed from the game.
