There is no formal minimum requirement, although a high combat level is recommended, since it is primarily combat-based.
In order you can complete the following quests that are to do with white knight, and doing the Wanted! quest will allow you to wear White Armour, below I will list quests and in Brackets what type of Armour it unlocks for you to wear along with it's bonuses.Recruitment Drive ( White Initiate armour - Looks like White Armour w/ Gold Trim, Same Defence as Steel Approx. W/ prayer bonus )Wanted! ( White Knight Armour - Same Defence as Black )Slug Menace ( Proselyte Armour - Best Melee Armour with same defence as Adamant, with additional Prayer Bonus ).
Proselyte armour.
Lv 40 defense
Granite if you have over 1mill.
ANSWER #1: It is worth it but you have to have level 40 in defence!
you need a defence lvl of 40
Temple knight armour may refer either to initiate armour (requirement: finish the quest "Recruitment Drive"), or to proselyte armour (requirement: finish the quest "Slug Menace"). You can buy it from Sir Tiffy Cashien, in Falador Park.
i guess full red dragonhide
Weapons don't add to your defence bonuses. The best armour, however, would be full rune.
you're sure it's steel?.. and are you sure your def. lvl is 8?
you might have killed him by accident at some point that's the only reason i can think of.
I'd say bandos, for the defence and the great strength bonus it gives. Barrows armour is awesome, but it degrades. The more better the armour, the more costly it is.
