Players cannot destroy the headband if players are in an area that requires a light source and it is the only light source you have in your inventory. Attempts to do so yields the message: Destroying the headband would leave you without a light source.
After 10 February 2009, the seer's headbands received some new bonuses. The Seer's headband 2 used to provide an extra set of logs when a regular tree was cut down in Seers' Village without any experience bonus. After the update, Seers' headband 1 now provided that ability, across the entirety of RuneScape.
If the ability that allows a player to get 2 logs from a regular tree is combined with the Evil Tree reward ability, it is possible to get over 10 regular logs all from the same tree.
When the Seers' Village Tasks were first released, all 3 headbands looked the same as the Seer's headband 1. This was fixed with the 10 February 2009 Seer's headband update.
There was a bug preventing the Woodcutting bonus for cutting maples trees if the player had grown the Maple tree him/herself. This was also fixed with the 10 February 2009 Seers' headband update.
When Seers' Village Tasks were released the Seers' headband 2 would remove the player's hair and make him/her bald when worn. This could only be fixed by visiting the barber in Falador. This glitch was later fixed.
