Sigbert the Adventurer

 is an NPC located at the end of the Yanille agility dungeon. He informs the player about the dangerous NPC Salarain the Twisted and how to defeat him.

The following are all 's lines.

NPC: I'd be very careful going up there friend.

Player: Why what's up there?

NPC: Salarin the twisted. One of Kandarin's most dangerous chaos druids. I tried to take him on and then suddenly felt immensely week. I here he's susceptable to attacks from the mind. However I have no idea what that means. So it's not much help to me.

Note: Week is the original word used in-game and is a spelling error (should have been "weak"), along with the word here which should have been "heard".

The second dialogue option:

Player: Fear not I am very strong.

NPC: You might find you are not so strong shortly.

As noted before the spelling errors still currently exists in-game and likely remains due to the 67 agility level requirement to access the area that inhabits.
