|Examine||Use astral, law, and cosmic runes to turn yourself into a comet and shoot yourself over the gap.|
A Comet platform is a platform found on the middle and top levels of the Runespan and is used to cross between islands. It requires an astral rune, a law rune, and a cosmic rune to use, along with level 55 Runecrafting. Using it will consume 3.9 Runespan points.
Runes will only be consumed when moving between two similarly sized islands, and from a larger island to a smaller one. Moving from a small island to a much larger island consumes no runes, to prevent players from getting stuck on dead end islands.
When using the comet platform, the player turns into a blue projectile which shoots into the air and falls down on the other side across the gap.
- This is the only platform to use astral, law, or cosmic runes.
