Sir Renitee's most significant function, however, is heraldry. He can tell players their family heritage, which gives them one of the following listed crests. For a fee of 5,000 coins, the player may choose their own crest – however, some of these crests have associated requirements, as noted below. Sir Renitee refuses to provide this service to any player whose Construction level (including any boosts) is below 16, the level required for an oak decoration.
Painting your crest on helms or shields turns them into members-only items; banners are always members-only. Once painted, a helmet or shield can never be reversed to its original state.
If a player has a money crest and needs to change it to a Saradomin crest for the Falador Hard Tasks, Sir Renitee will give the player a one-time money crest voucher that can be used to change the crest back afterwards for only 5,000 coins (instead of another 500,000 coins).
The 'Skull' crest once required a player to be skulled before speaking to Sir Renitee. Since the removal of skulling, the crest had no additional requirements. However, since the introduction of Legacy Mode, becoming skulled once again returns, and once again the 'Skull' crest requires the player to be skulled.
