The ruby golem outfit is a Mining outfit that can be acquired via Treasure Hunter, or made via the Invention skill. The outfit pieces can each be made at Level 80 Mining and Level 20 Invention by combining 3,600 gemstone golem fragments at an Inventor's workbench, after discovering the Magic golem outfit blueprint at the workbench.
The Ruby golem outfit can be combined with the Sapphire golem outfit and Emerald golem outfit to make the Magic golem outfit for additional benefits. Pieces of the Ruby golem outfit may be traded for other pieces of the three golem outfits. They cannot be traded for any other items.
When the full set is worn, it has the following effects:
- +5% success chance while Mining (stacks with the Quarrymaster auras).
- Uses Golden mining suit bonus experience if owned, even while the set is in the bank, player-owned house or with Diango. If you don't own the full Golden mining suit it will work for as many pieces as you have, although if you have neither a full Golem suit or a full Golden mining suit then you should only wear the Golden mining suit pieces you have, as an incomplete Golem suit will not act like the Golden mining suit pieces. If you obtain a golden mining suit piece while wearing a full Golem outfit, the xp boost from that piece will not immediately be added; you have to equip it at least once for its xp boost to work while wearing a full Golem suit.
- Players who have any version of the Varrock armour will get the chance of mining double ores up to the respective version unlocked.
They were later made available again by purchase from Vic's Store, on the release of the store on 29 September 2014, for a 500 credits per outfit piece. The outfits have also returned in Vic's store on every subsequent re-opening of the store (the store itself only ever appearing in-game on a temporary basis).
On 20 August 2015, the outfits were re-added to Treasure Hunter permanently, and later an update on 14 November 2016 added the ability to make the outfits by collecting and combining gemstone golem fragments.
