Spirit terrorbird

A Spirit terrorbird is a summoning familiar, and can carry up to twelve items. It cannot hold untradeable Items nor items that are deemed "too valuable". In addition to that, Spirit terrorbirds cannot hold Rune essence or Pure essence.

Once summoned, the Spirit terrorbird will disappear after 36 minutes, even if the player's Summoning energy is equal to zero before the end of the 36 minutes, dropping all its inventory. The player is alerted one minute, and then 30 seconds before the Spirit terrorbird disappears.

Spirit terrorbird pouch
Spirit terrorbird pouch is made by using a Summoning pouch on a Summoning obelisk with 12 spirit shards, a Gold charm and a raw bird meat in the inventory. Making the pouch earns 68.4 experience points. Using the pouch to summon a Spirit terrorbird gains 0.8 experience points, and costs 6 Summoning points.

Tireless run scroll
Tireless run scroll enables the use of the Tireless Run special move for a Spirit terrorbird. Using the pouch on a Summoning obelisk creates 10 scrolls.

Tireless Run
Tireless Run is a special move for Spirit terrorbirds, which:


 * restores the player's running energy by half of the player's Agility level rounded up
 * temporarily increases the player's Agility level by 2 levels.

Tireless Run is very useful when players have to run for a long time, such in the Summer's End quest, or while doing a special task like an Agility course or doing the Pyramid Plunder mini game were players have to do a lot of running in a short period of time. However, familiars are prohibited to enter certain places where unlimited run would be useful (For example, they cannot enter the Ape Atoll Agility Course, Dorgesh-Kaan Agility Course or Brimhaven Agility Arena). Some players find Tireless Run useful when Runecrafting, particularly when using the ZMI altar. However, this cannot be used when runecrafting law runes, because Summoning familiars aren't allowed in Entrana. And unlike the abyssal familiars, it can't be used to carry rune or pure essence.

Trivia

 * The Spirit Terrorbird resembles a blue coloured Chocobo from the Final Fantasy games series. Even its size compares to that of a regular Chocobo.


 * The Tireless Run ability might have something to do with its likeness of a Chocobo as they are known for being able to run for vast amounts of time with out breaks for breath.
