A skills necklace is a dragonstone necklace that has been enchanted with the spell Enchant Level 5 Jewellery.
A freshly enchanted dragon necklace will have zero charges. It can carry up to four charges, each of which can be used to teleport to the entrances of the following guilds:
Like the other enchanted pieces of dragonstone jewellery, the teleports of a skills necklace can be used in up to level 30 Wilderness, instead of level 20, the normal limit for teleportation.
As long as it has at least one charge, a worn skills necklace will slightly increase the chance of finding a casket while fishing with a big net.
When it runs out of charges, it can be recharged at the totem pole in the Legends' Guild or the Tears of Seren fountain in Prifddinas. A geyser titan cannot recharge a skills necklace.
