In Old School RuneScape (OSRS) Leagues 5: Raging Echoes, one of the more interesting and challenging bosses to tackle is the Echo Thermonuclear Smoke Devil. This boss is part of the special Echo version introduced during this year's Leagues event, and it offers a unique challenge, especially for players who selected the Kandarin region. Despite Magic being perceived as weak compared to other combat styles in this League, the Thermonuclear Smoke Devil is still a rewarding boss to fight once you've met the necessary requirements. In this guide, we'll walk you through everything you need to know to defeat this boss and claim the Devil's Element.

Requirements for the Echo Thermonuclear Smoke Devil

Before jumping into the fight, it's essential to meet the necessary requirements:

Level 93 Slayer: This is the hard requirement for being able to kill the Thermonuclear Smoke Devil.

 If you’re just starting in the Leagues, you won't be able to take on this boss until you’ve leveled up your Slayer.

Level 94+ Magic: As this is a Magic-based fight, you’ll need to have sufficient Magic levels to deal damage effectively. Ensure your Magic level is at least 94.

Level 43+ Prayer: Prayer is crucial for protection against the boss's various attacks, so make sure you have a decent Prayer level.

Autocast Staff: A staff like the Trident of the Seas or any other strong Magic staff is necessary to cast powerful Magic spells. If you plan to use Ancients, a Scepter will work well.

Karambwans or Better Food: For healing, you'll want to bring Karambwans, which provide both healing and the ability to use Protect from Magic more efficiently.

Prayer Potions: These are useful, especially if you don't have access to relics that extend your Prayer.

Decent Magic Gear: Gear that boosts your Magic attack and defense will improve your chances of survival.

Facemask or Slayer Helmet: These provide crucial protection against the Smoke Devil’s attacks.

Echo Thermonuclear Smoke Devil Strategy

To successfully defeat the Echo Thermonuclear Smoke Devil, the key is understanding its attack patterns and knowing how to position yourself. Before engaging, it's highly advisable to wait until you’ve unlocked at least Tier 6 Relics, which include Total Recall and Banker's Note. These relics make your trips much easier by reducing the need for items like Prayer potions and food.

Boss Mechanics

The Thermonuclear Smoke Devil’s attacks are straightforward, but they require precise movement and timing:

Ranged and Magic Attacks: The boss alternates between two attack types: a Ranged attack that looks like a floating rock and a Magic attack in the form of a sparkling blue ball. To mitigate damage from these attacks, simply use Protection Prayers. During the first half of the fight, the boss will always use 3 Ranged attacks followed by 3 Magic attacks. In the second half, the pattern switches to Ranged, Magic, and then Ranged.

Pink Circles: Throughout the fight, pink circles will appear on the ground. These are vital to surviving the boss’s hits. After each attack, you’ll need to move to the next pink circle to tank the hit. For every hit you take, one circle will disappear, so you’ll need to keep moving. There are 12 circles in total that appear in each rotation.

Charge Attack: After each rotation, a yellow bar will fill above the boss’s health. Once the bar is full, the boss will launch a devastating charge attack. To avoid taking heavy damage, pray Magic and move as far away from the boss as possible. This attack does more damage the closer you are to the Thermonuclear Smoke Devil, so distance is crucial. Before running away, be sure to equip a ranged weapon and hit the boss once, as the Thermonuclear Smoke Devil will pray against the last damage type it received. This attack doesn't require a hit to land, so even a 0 damage hit will cause the boss to switch to Protect from Ranged.

Full Kill Strategy

Here’s a step-by-step breakdown for a successful kill:

Prepare for Battle: Before entering the boss room, ensure your facemask or slayer helmet is equipped, and turn on your offensive prayers. Equip your Magic staff and prepare to use Protection from Magic and Protection from Ranged during the fight.

Attack the Boss: Once inside, position yourself on top of the nearest pink circle. Begin attacking the boss with Magic. After each attack, if you take damage, quickly move to the next circle. When you take 3 hits, switch your prayer to Protect from Magic. After 3 Magic hits, switch back to Protect from Ranged. Repeat this rotation until you’ve completed the 12-hit cycle.

Charge Attack: After the 12th hit, the yellow bar will fill up, signaling the charge attack. At this point, switch to your ranged weapon (preferably a knife or shortbow), hit the boss, then move as far away as possible while praying Protect from Magic.

Ranged, Magic, Ranged Pattern: Once the boss drops below 30-40% health, it will switch to a more complicated attack pattern (Ranged, Magic, Ranged). You can either Protect from Ranged and move through the pink circles or alternate between Protect from Ranged and Protect from Magic if you’re fast with your prayers.

Conclusion

With these strategies in place, you should be well on your way to defeating the Echo Thermonuclear Smoke Devil in OSRS Leagues 5: Raging Echoes. While the fight is relatively simple, it does require solid gear, patience, and fast reflexes. The reward, the Devil's Element, is worth the effort and provides an excellent boost for those progressing through the League. Keep practicing, and soon you’ll be adding this boss to your growing list of Leagues achievements!
