Clawdia

Clawdia is a boss monster featured in the Summer Beach Party, in the centre of the Lumbridge Crater. She is a large crustacean that appears once every hour at the 45 minute mark, signified by a start of rain in the area. If she is not defeated after 5 minutes, she will retreat. Rewards are still granted to players fighting her at that time.

Clawdia deals damage in all attack forms from 1-10% of your current lifepoints, all of her attacks deal AoE damage (Area of effect). She has 5 attacks:
 * Melee AoE: This deals damage in a large area in the direction Clawdia is facing.
 * Ranged AoE: A small area of damage in front of her. Clawdia claps her front pincers together and shoots a conic shockwave, which is only visible in standard detail.
 * Magic DoT: This is a 1x1 damage over time attack that lasts about 10 seconds
 * Water Jet: Clawdia slowly spins and deals typeless damage to players in her line of sight.
 * Splash AoE: This is a very large AoE attack that deals melee damage to all attacking players.

Deaths to Clawdia are not safe, meaning items are lost upon death and Hardcore Ironman Mode players will lose a life. However, since Clawdia does damage according to your current health, it is very difficult for her to kill you.

The title is acquired after helping defeat Clawdia 50 times.

It is possible to defeat Clawdia more than once per hour by switching worlds. While she dies very quickly in members worlds (as little as under 10 seconds in highly populated worlds), she takes a much longer time to kill in free worlds and members could switch there for at least one additional kill. Remember that you cannot attack on a free to play world if you have a members weapon equipped. Clawdia despawns in 5 minutes if not killed, but players who have engaged her in combat will still be rewarded.

Before the event when players could hand in sand one possible dialogue has Reyna noticing a small crustacean in one of the buckets. During the event, she states to the player that Clawdia arrived at the beach in one of the buckets of sand donated, then an "adorable little creature". She also states that the Wizards' Tower claims that Clawdia was sent as a defender by Gielinor to retaliate for the Battle of Lumbridge.
