If you main a mage build in Enshrouded, you’ve probably spent hours hunting for spells that can melt even tanky Wraiths and Shrouded bosses without constant recharging. That’s why so many players are asking how to get eternal fireball enshrouded, a rare infinite-use fire spell that bypasses the usual mana cost restrictions for standard offensive spells. I’ve tested every possible route to unlock it over three playthroughs, and this guide breaks down exactly what you need to do, no guesswork included. You don’t need to be at max level to start the quest line, but you will need access to a few mid-game regions first.
Prerequisites You Need Before You Can Get Eternal Fireball in Enshrouded
First off, you can’t rush this spell early on, no matter how badly you want it. There are a few non-negotiable boxes you need to tick before the quest to unlock it even appears on your map. I made the mistake of wandering the Shrouded lowlands looking for clues at level 12, and wasted almost two hours before I realized I was missing key unlocks.
First, you need to have rescued the Alchemist NPC from the Ancient Spire in the Revelwood region. He’s the only NPC that can give you the starting quest for the eternal fireball, and he won’t offer it until you’ve completed his first three side quests for potion crafting. You also need to have at least 12 points in the Intelligence skill tree, so the game recognizes you’re running a mage build and prioritizes the spell quest for you.
Finally, you need to have cleared the Shrouded barrier in the northern part of the Sunken Tombs area. The actual spell is hidden in a chest deep inside a hidden dungeon there, so you can’t reach it until you’ve cleared the toxic Shroud from that section of the map. If you haven’t upgraded your Flame Altar to level 4 yet, do that first before you start this process.
Step-by-Step Walkthrough to Unlock the Eternal Fireball
Once you’ve hit all the prerequisites, the unlock process is straightforward, but there are a few hidden traps you can avoid if you know what to look for. I missed the second rune activation on my first run, so I had to restart the entire dungeon, which was a huge pain. Follow these steps exactly to get the spell on your first try:
- Talk to the Alchemist at your base, and accept the quest called “Eternal Flame for the Forgotten Mage”. He’ll give you a damaged fire rune and a map marking the entrance to the Sunken Tombs hidden dungeon.
- Travel to the marked dungeon entrance, and use the damaged rune to open the sealed stone door. You’ll face three waves of level 22 fire Imps first, so bring a few fire resistance potions to cut down on incoming damage.
- Find the three hidden rune pedestals scattered across the dungeon’s lower level, and activate each one with a small fire essence. You can farm fire essence from any fire-based enemy in the Revelwood region, or buy stacks of it from the Alchemist for 25 gold each.
- Once all three runes are activated, the sealed boss room will open. Defeat the Forgotten Mage boss, and loot the golden chest behind his throne to get the eternal fireball spell.
That boss only has one big attack you need to watch out for: a large area-of-effect fire blast that deals 80% of your max health in damage if you’re within 10 feet of him. Just back up when you see him start to channel the spell, and you’ll take him down in 2-3 minutes even if you’re only level 20. You don’t need any fancy gear for this fight, just decent fire resistance and a backup spell for when you need to heal mid-battle.
Key Perks and Limitations of the Eternal Fireball Spell
A lot of players see the word “eternal” and assume this spell is completely unbreakable, but that’s not quite true. It has some huge advantages over standard fireball spells, but there are a few drawbacks you should know before you invest all your skill points into boosting its damage.
The biggest perk, obviously, is that it doesn’t consume mana or spell charges. You can cast it as many times as you want, no cooldown beyond the standard 1 second cast time for fire spells. That makes it perfect for clearing large groups of weak enemies, or chipping away at boss health bars without having to stop to drink mana potions every 10 seconds. It also deals 15% more damage to Shrouded enemies than a legendary tier standard fireball, which is a huge bonus for endgame Shroud runs.
But there are a few downsides too. First, it can’t be modified with the Alchemist’s spell fusion upgrades, so you can’t add splash damage or burn effects to it like you can with regular fire spells. It also has a slightly shorter range than a max upgraded standard fireball, so you have to stand a little closer to enemies to hit them. Finally, it will not work at all if you’re in a region with a Shroud level higher than 5, so you can’t use it in the deepest endgame Shroud zones.
I still keep it on my main spell bar 90% of the time, but I keep a fused legendary fireball on my second bar for high level Shroud runs. That balance works perfectly for almost all content in the game, and I rarely find myself switching to other offensive spells for regular overworld exploration.
Tips to Maximize Eternal Fireball Damage for Your Build
Even though you can’t fuse the eternal fireball with other spells, there are still plenty of ways to boost its damage to make it viable even for late game boss fights. I’ve tested dozens of skill and gear combinations, and these tweaks give you the biggest damage boost for the least investment.
First, invest 5 skill points into the Pyromaniac perk in the Intelligence skill tree. That gives you a 25% permanent damage boost to all fire spells, including the eternal fireball, and it also makes you 30% resistant to fire damage, which cancels out the small self-damage you take if you cast the spell too close to walls or obstacles. This perk is a no-brainer for any fire-focused mage build, even if you don’t use the eternal fireball as your main spell.
You also want to look for gear pieces that have “+Fire Spell Damage” as a secondary stat. A full set of legendary mage gear with fire damage bonuses will add another 40% damage to the spell, which is enough to one-shot most regular overworld enemies at level 25. If you can get an amulet that boosts infinite use spell damage specifically, that’s even better, as those stack with the fire damage bonuses to push your output even higher.
One trick I stumbled on by accident: if you cast the eternal fireball right after using a fire potion buff from the Alchemist, the damage boost lasts for 10 full casts instead of the usual 30 second timer. That’s perfect for boss fights, as you can pop the potion right before you pull the boss, and get 10 high damage casts in before you need to reapply the buff. It saves you a ton of gold on potion costs over time, too.
Don’t waste skill points on cast speed upgrades for this spell, though. The cast time is already capped at 1 second, so those upgrades won’t do anything at all for the eternal fireball, even if they work for your other spells. Put those points into damage or resistance perks instead, you’ll get far more value out of them.
The eternal fireball is easily one of the most useful mage spells in the entire game, and it’s worth the hour or two of work it takes to unlock it, even if you only occasionally play a magic build. If you follow the steps we laid out, you won’t run into any of the common snags that slow most players down when they’re trying to get eternal fireball enshrouded. Once you have it, you’ll wonder how you ever played a mage without infinite, zero-cost fire damage at your fingertips.
