The Wonderful Funcitons of RS Summoning Familiar
It is possible for a Summoning pure/skiller to use summoned creatures to attack others without the risk of raising Constitution experience. For example, if the player had a Desert Wyrm summoned, he was able to use the Electric Lash scroll to deal damage without worrying about obtaining experience in Constitution.
These familiars can fly into the air and permit the player to see through their eyes, giving the player the skill to see things much further away.
These familiars can heal a player's life points at a given rate. For example, the Bunyip heals a player 146 Life Points every 15 seconds.
A forager will discover certain items from time to time, and can carry up to 30 of a specific type of item. Players are only able to withdraw items from these familiars, not deposit items in them.
