Cosmic meteor

Cosmic meteor is a Random event associated with Mining. When this random event occurs, a meteorite will crash down from the sky. If you mine this meteor, you will receive assorted types of ores, as well as gems and Rune essence.

This event is mainly prized for the Starblades that can be obtained. Mining these meteorites take time, and depending on your mining level, you can receive lots of different ores, gems, and essence.

After a random amount of time, the meteor will explode. Mining all the way through the meteor to the starblade in the center before this happens is uncommon, and is easier if your mining level is higher.

Loot

 * Any mining level: Copper ore, Tin ore, Uncut sapphire, Rune essence


 * Mining level 10+: Iron ore, Silver, Uncut emerald


 * Mining level 25+: Coal, Gold ore, Uncut ruby, Pure essence


 * Mining level 50+: Mithril ore, Adamantite ore, Uncut diamond


 * Mining level 75+: Runite ore, Uncut dragonstone

In addition, if you manage to completely mine out the meteor before it explodes, you will find either a Dark starblade or a Light starblade in the center. The odds of receiving each starblade depend on your combat stats. Players with an Attack level higher than their Defence level are more likely to receive the Dark starblade, and vice versa.

Think of it this way. A player has 62 Attack and 44 Defence, so the chance of them receiving the Dark Starblade to the Light Starblade is 62:44.

You will receive the Dark starblade or Light starblade from the "Star Sprite" in the center of the rock after mining the rock of all of it's layers.
