Buy RS3 Rune platelegs
Rune platelegs are tier 50 melee leg armour in RuneScape 3. You need level 50 Defence to wear them. They count as tank armour and fill the leg slot. They give 187 armour, a 750 life points bonus, 1% damage reduction against monsters, and 2.625% damage reduction against other players.
These platelegs are a solid pick for players who want strong defence at mid levels. They are light too, weighing only 0.015 kg. The item is tradeable, lendable, and noteable. It is free to play, so any player can use it.
Players with level 50 Smithing can make them at a forge and anvil with 3 rune bars for 720 Smithing experience. They can be upgraded to +1 with 3 more bars, and higher tiers go up to +3. They also drop from Animated Rune Armour at level 81.
Rune platelegs can be combined with a Rune full helm, Rune platebody, and Rune kiteshield to form a Rune armour set at the Grand Exchange clerk. They can also be disassembled for parts like Plated parts, Strong components, and Protective components.
