Tam McGrubor

Tam McGrubor is a member of the Zamorak Magical Institute who hands out wicked hoods to members, regardless of their skill levels. He can be found just south-west of Horvik's Armour Shop on Varrock square, near Benny. When talking to him he will also explain some basic details about how the Runecrafting skill works. He will not give you a second hood if you already have one. If the hood is lost, he will give you a new hood for free. He could possibly have ties to McGrubor's Wood.

It is likely that there is a sinister purpose behind his free distribution of wicked hoods, as he is a member of the ZMI, and it is mentioned in a game FAQ that "You want to wear it (the wicked hood). You want others to wear it. Soon, everyone will be wearing one. Tam is pleased. Tam's plans come to fruition."
