World Boss Ashava the Pestilent is ready to stomp your face in Diablo 4
World bosses are a new addition to the franchise in Diablo 4, designed to be “truly gigantic, horrific monsters” so large that the in-game camera zooms out so you can see the whole battlefield. The Act 1 world boss, Ashava the Pestilent, was available on spawn rotation for testing during both beta weekends and the Server Slam. Let’s review the basics you need to know for the live game, including quick tips for reference!
World boss encounters are open-world events, where you and your fellow denizens of Sanctuary pull together to defeat the massive invader. According to the devs, these bosses will “take more than the people in your party to fight it.” That said, you shouldn’t have trouble because Diablo 4’s multiplayer features mean the fight is open to you and 11 other players when a world boss spawns (splitting off to a new ‘instance’ for each grouping).
Find and unlock Ashava in Diablo 4
World bosses spawning during Act 1 was a unique feature added to the various betas for testing. All World Bosses spawn after you finish the main campaign. This is good encouragement to finish the story before diving into the deep end.
You’ll find Ashava in The Crucible in the southeast of the Fractured Peaks (where Act 1 takes place). The Crucible is a dedicated location for the massive demon, acting almost as a container boundary for the fight. It should be easy to find Ashava, because a special event icon will show up on the map a half hour before it spawns, telling you exactly when and where to find the boss.
With the massive size of the world in Diablo 4, we did find getting to Ashava — even knowing in advance when exactly it would spawn — to be time-consuming. We’re still waiting on the final spawn rotation, but know that world bosses will spawn at intervals at their locations scattered throughout Sanctuary; regardless, be sure to head out in advance to participate in these giant boss battles. But be forewarned — Ashava was not for the faint of heart (or low of level). You’ll want to prepare for a world boss battle in Diablo 4.
- Complete the campaign first — you won’t see world bosses before this is done.
- Plan ahead — Check the map for a countdown timer to the encounter. When you see the countdown, start hustling to the spawn location.
Tips for fighting Ashava (and other world bosses) in Diablo 4
Fighting Ashava requires more awareness than strategy, as players have to be careful to watch for its attacks and dodge appropriately. Practice with the game’s evade mechanic, which lets you quickly dodge away from danger. Being quick with this action is a must to avoid the massive damage this world boss could dish out. Gear that gives you extra evade charges or reduces the evade cooldown helped as well. being mindful of the mechanics and getting out of the way of attacks is crucial with both boss encounters throughout Act 1 story quests and dungeons. Dodging behind the boss during an ability prevents one-shots.
World boss fights are not a one-shot and done, and you may not have enough health potions (by default) to just heal through the damage. Pay attention to the world boss action bar — each milestone / breakpoint in the fight is represented in the boss bar in the top of the screen with a red triangle pointing down. As each milestone is reached, the triangle reverses (pointing up) and turns gray; when this happens, the boss drops health potion charges in the surrounding area to top you up while kicking off an additional mechanic.
These milestones are critical for your survival for a second reason — you should try not to teleport away from the fight. You run the risk of losing your instance of the world boss fight if you open a town portal to Kyovashad for repairs. Yes, your gear may end up entirely in the red and desperate for repair; don’t fall to temptation! Stick it out and apply as much damage as you can.
You want to keep an eye on the boss’ bar for a second reason — the newly added stagger mechanic. Stagger is a way for players to bring their controlling effects (such as stuns) to the boss fight. In the past, these abilities would not have any effect but with stagger, crowd controls accrue on the boss and fill up the stagger bar (showing as a thin yellow bar under the boss’ health bar when charging up).
Once the stagger bar is filled, it turns blue and immediately begins counting down, with a starting window of at least 12 seconds. During this time, the boss is staggered and you have an open window to absolutely blast at the boss without it retaliating. This is the perfect period for slamming Ashava with your ultimate skills! Stagger can also mitigate the boss’ more dangerous attacks; with Ashava, this means a smaller radius during the second sweep arc, giving you a bigger window to dodge from lethal damage.
- Watch the moves telegraphed by the boss and evade behind the boss.
- Monitor the boss’ health bar for both milestones and stagger progress.
- Eye the ground for health potion charges once the milestone arrow flips.
- Use your control effects on the boss to contribute to the stagger meter.
- Unleash hell when boss is staggered (meter bar flips from yellow for charging to blue counting down).
We got our first glimpse at Diablo 4’s world bosses way back at BlizzCon 2019. They’re huge, menacing, and ready to murder a whole heap of players. World bosses are another example of Blizzard embracing the “large and open” concept. Yes, it is possible to solo these absolute monstrosities, as you can see in Wudijo’s video above, so ultimately you can master these bosses with time, patience, and strategy.
Diablo 4 has a massive open world to explore, and world bosses are only one of the dangerous encounters you might run into while exploring — like in all Diablo games, you should beware of the Butcher. All of these dangers remind players that Sanctuary is no longer safe, no matter where you roam. And if you see a world boss that’s ten times your side, you may want to run for it.
