OSRS Guide: How to Kill the Mimic
Jul-30-2025 PSTThis is a guide on how to kill the Mimic in Old School RuneScape. The Mimic is a unique boss that players can fight as part of the treasure trail (clue scroll) system. In this guide, I'll explain how to unlock the fight, how to get the Mimic casket, the recommended stats and gear, the mechanics of the fight itself, and some useful tips to help you win and get the best rewards possible.
How to Unlock the Mimic Fight
Before you can fight the Mimic, you need to enable the challenge. To do this, go to Watson's house in Hosidius. Watson is the NPC who combines clue scrolls into master clues. His house is in the south-eastern part of the Hosidius region in Great Kourend.
You can get there in two ways:
· Use a Xeric's Talisman to teleport to Xeric's Glade and run west.
· Use a Watson teleport scroll, which brings you directly to his house.
Once you're there, go upstairs and find the Strange Casket. Right-click it and select the option to enable the Mimic challenge. You only have to do this once.
How to Get a Mimic Casket
After enabling the challenge, you have a chance to receive a Mimic casket whenever you open an elite or master clue scroll reward. This doesn't happen every time. For elite clues, the chance is around 1 in 35, and for master clues, it's about 1 in 15.
When you do receive one, you'll see a message asking if you want to fight the Mimic. If you accept, the clue casket becomes a Mimic casket, which you can use to start the fight.
Recommended Stats
The Mimic is not one of the most difficult bosses in the game, but it does hit hard and can be dangerous if you're not prepared. I recommend the following combat levels before attempting the fight:
· 90 or higher in combat stats is ideal
· At least 85 Magic
· 80 Strength and Attack
· 70 Defence
· 70 or higher Prayer
Gear Setup
The main source of damage in this fight should be magic. Melee is only used for a quick special attack at the beginning of the fight. Bring both a magic setup and a melee special attack weapon.
For your magic gear, try to bring:
· Ancestral robes, Ahrim's, or Mystic robes
· Kodai Wand, Trident of the Swamp, or Sanguinesti Staff
· An Arcane Spirit Shield or Mage's Book
· Eternal Boots or Infinity Boots
· A Seer's ring (imbued if possible)
· Tormented Bracelet or Barrows Gloves
· A god cape or Ardougne cloak
For your melee special attack weapon, choose one of the following:
· Voidwaker (best option)
· Dragon Claws (good burst damage)
· Dragon Dagger (p++) for a budget option
Inventory Setup
Here's a recommended inventory layout:
· Magic potion or Imbued Heart
· Super combat potion (for melee boost)
· 1 or 2 prayer potions
· 1-2 Saradomin brews or sharks for healing
· Special attack weapon
· Teleport out in case of emergency
· Food: Sharks, Karambwans, or Anglerfish
Getting to the Fight
To start the fight, go back to Watson's house. Bring the Mimic casket with you and use it on the Strange Casket upstairs.
Before you enter:
· Drink your potions
· Turn on Protect from Melee
· Equip your melee spec weapon
· Get ready to quickly switch to your magic gear after the spec
The Mimic Fight: Mechanics
The Mimic has three types of attacks you need to watch out for.
1. Melee attacks – These are straightforward and are mostly blocked with Protect from Melee.
2. Candy attack – The Mimic throws out six candies that land in different spots around the room. Some deal damage, and some spawn small minion mimics. Don't waste time fighting the minions; just focus on the boss. Move around to avoid the candies when you see them fall.
3. Stomp attack – If you stand directly under the Mimic, it will perform a stomp that deals heavy damage. If you find yourself under him, move out of the way immediately to avoid it.
Strategy to Kill the Mimic
1. Start the fight by using your melee special attack weapon. Drop both specs quickly (Voidwaker or Claws work best for this).
2. After using your specials, immediately switch to your magic gear and start attacking with your main spell.
3. Keep Protect from Melee on throughout the fight.
4. When the candy attack happens, stay mobile and avoid standing still. Ignore the minions unless you're in trouble.
5. Don't stand underneath the boss to avoid getting stomped.
With decent stats and good gear, the fight should be over in under a minute. If you struggle, consider upgrading your gear or bringing more food.
Rewards and Why It's Worth It
The Mimic acts like a master clue casket. That means you can get all the regular master clue rewards, including:
· Third Age equipment
· Ranger boots
· Gilded items
· Rune and Dragon items
· Unique cosmetic items
In addition to regular clue loot, the Mimic also has a rare chance to drop:
· The Mimic pet – a miniature version of the boss
· Unique log items for Collection Log completion
The rewards can be extremely valuable, and if you're doing clue scrolls regularly, it's worth enabling the Mimic fight for the extra fun and profit.
Tips and Common Mistakes
· Don't waste time fighting the minions that spawn from the candy attack. They're not worth the effort.
· Always move during the candy phase. Staying still is risky.
· Use your special attacks right away at the start of the fight to burst down some of the Mimic's health.
· Never stand underneath the boss.
· If you're low on health or undergeared, don't be afraid to teleport out. You won't lose anything and can try again later.
Conclusion
The Mimic is a great addition to Old School RuneScape for clue hunters and PvMers alike. It adds a fun, fast-paced boss fight to clue scrolls and offers a shot at high-value loot and a rare pet. As long as you're prepared, understand the mechanics, and use your OSRS gold & gear wisely, the fight becomes an easy way to turn clues into profit.
Thanks for reading this guide. I hope it helps you take down the Mimic with confidence. Good luck on your next casket, and may the loot be in your favor.
