The Security guard was a random event. If a player had their recovery questions set, the guard would give them a security book, another reward that you were recommended by the security guard was to come to the Stronghold of Security. He can now be found on the 1st floor[ of the ]Port Sarim Jail.
The Possible rewards were included were:
- 20, 40, 80, 160, 320, or 640 coins
- Uncut gems (sapphires, emeralds, rubies, or diamonds)
- Half key (members only)
- Cosmic talisman (members only)
- Spinach roll
The guard could also be attacked and killed, but this is not recommended, despite his max hit of 2, he had high Defence and a total of 250 Hitpoints, and the damage done to him only gives you a quarter of an experience point per damage done. Also, he is immune to poison. If you take too long to kill him, he will eventually disappear.
If a player decides to fight him, he is weak to stab attacks and Magic. Rangers will have an easy time against him, too. This is not recommended, as you will only gain a quarter of an experience point each hit while fighting a Security Guard. Additionally, despite advertising the Stronghold of Security, he still comes when you actually are in the Stronghold. If you teleport away, he will say 'He/She got away!' before disappearing.
If the player already possess a security book in his inventory, the NPC would not provide another one.
