We've decided that perhaps some players deserve a reward after completing everything in the game, but that's not as easy as it sounds.
Once you have completed the game, you will now earn a "Staff of Completion" and the upcoming "Completionists Cape". These items both have special abilities, the staff of completion can open the bank for you and or cast vengence for free with a 5 second time delay. The completionists cape, when worn, will raise all your stats by +10.
To obtain these items, you must complete the following;
Complete all quests.
Get 99 in at least 24 skills.
Completed the Portals of Redemption D&D at least once.
Killed a KBD at least once.
Killed a Kalphite Queen at least once.
Killed 1 of each God at least once (General Graardor, Kree'ara. etc.)
Once you have done all of this, you can then go speak to "Master Yen" to purchase a completionists cape and staff for 99,000gp.
Have fun! ;3
