Chaeldar

Chaeldar is the fourth most-advanced slayer master in RuneScape. She is found in the throne room of Zanaris, directly south of the entrance from the Lumbridge Swamp. She gives out mid to high level Slayer tasks which may only be attempted by players with a combat level of 70 or higher. She gives 10 points per task completed, 50 for every 10th task and 150 for every 50th task. It is recommended players use this slayer master with at least 60 defence.

Fairy rings
The Fairy ring network is a useful method of doing Chaeldar's Slayer tasks. It has teleport spots close to the Slayer Tower (CKS), the Fremennik Slayer Dungeon, (AJR), and other locations to be reached easily for no cost to the player - all of which contain the slayer monsters that she assigns. However, you need to have reached a certain point in or completed the quest Fairytale II - Cure a Queen.

Assignments
NOTE: Slayer masters assign higher-levelled monsters more frequently if the player's combat level is high.

Slayer Challenge
After a player has performed several slayer tasks for Chaeldar, she will occasionally offer a special task in place of a regular slayer task. The player can decline to take the special task without penalty. If the player accepts the special task, completing the task: Chaeldar's special task is for the player to test an experimental fungicide spray against ten Zygomites and survive to return to her and tell her the results of the test. The player uses the spray in place of the normal Fungicide spray, when the zygomite the player is attacking has been reduced to 20 life points or less. When applied, the experimental spray will have one of the following effects, chosen randomly: Note that the challenge is only complete when the player returns to Chaeldar and speaks to her; simply killing 10 zygomites with the experimental spray does not finish the task. The spray cannot be used to kill more than the required 10 zygomites.
 * Earns 10,000 extra slayer experience.
 * Earns 25 Slayer reward points, if the player has completed the Smoking Kills quest.
 * Counts as a task for the player's consecutive task count, which is used for slayer reward points.
 * "The experimental spray has sent the zygomite into a furious rage!" The zygomite temporarily turns red, heals a bit, and attacks faster. It can be killed by reducing its life points to 0, without needing another application of the spray.
 * "The experimental spray has healed the zygomite!" The zygomite temporarily turns green and its hitpoints are restored to maximum. It can be killed by reducing its life points to 0, without needing another application of the spray.
 * "The experimental spray has killed the zygomite!" The zygomite is killed.

Trivia

 * Chaeldar used to refer to Harpie bug swarms as "Harpie bugs," while Vannaka called them by their proper name. This has since been fixed.
 * In Postbag from the Hedge 26, Chaeldar copies, almost verbatim, a quote from Yoda in the Star Wars series.
 * In reference to what Chaeldar states in the Postbag from the Hedge 26, she mentions her Battle Axe, which in return should no longer be correct, due to the graphic overload of Zanaris, and its fellow fairies. Her weapon up-to-date resembles a leaf-bladed spear.
 * In the same issue of Postbag from the Hedge, Chaeldar is quoted saying "Float like a butterfly, sting like a bee"; a quote coined by the famous boxer Muhammed Ali.
