To get to the Bandos Throne Room you can either make a Bandos Throne Room sphere from Oldak (requires 2 law runes and 1 molten glass) or use the code BLQ with the fairyrings. You must try to climb on the statue first before it will come to life. The throne room is multicombat.
These are powerful, so wear the best armour possible. It's recommended that you use super potions, high healing food, and a Summoning familiar if possible. You can also kill it with Range, Mage, or a halberd from a safespot. Simply stand in front of the throne and it won't be able to hurt you.
