Wipefest: Fractillus Crystal Wall Support

Quick Links

Wipefest & Retail Warcraft

Last updated: September 12, 2025

is one of the more unique raid fights we’ve seen in World of Warcraft. Aside from the usual boss mechanics and damage avoidance, the only way to progress past this elemental guardian is to properly manage the placement of Crystal Walls, ensuring that none of the six lanes ever have more than 5 walls at any time to avoid the

enrage.

If your raid group is struggling to figure out where they’re going wrong, Wipefest now supports the wall placement mechanic when analyzing your Warcraft Logs report!

How it Works

You can now step through each cast of

to see who placed each wall, the current state of all lanes at that point in the fight, as well as which types of walls were spawned (for Heroic and Mythic difficulties). The colored lines represent Crystalline Walls and are color coded as such:

Green → New walls

Red → Destroyed walls

Blue →

Dark Blue →

White →

Dev Insights

This was a fun challenge to implement on Wipefest! Why?

We spoke with Vollmer, who was the developer of this feature, and here's what he told us:

"Working on this insight was an interesting challenge. In essence, it can be treated as a trigonometry problem, since the fight takes place within a large arc. The main hurdle we had to overcome was figuring out how to define the different lanes, and in turn, figure out which lane a player was standing in at a given point in time.

To achieve the former, we first had to find the “upper” and “lower” bounds of the boss area, and then split the arena into equally sized arcs. For the latter, we brushed off some high school math to work out the angle a given player had in relation to the boss, which we could then use to work out which lane a player was in.

On paper, this solution seemed easy to implement, since you could just take the coordinates from the boss and the player, work out the angle, determine their lane, easy peasy lemon squeezy. But when initially testing the implementation, we kept getting mismatched placement, which required a deeper investigation.

After some more scouring through combat logs, we found that the boss actually has a different position than is recorded in the events! In order to figure out the boss’s position, we needed some other approach to calculate his true position. It turns out that Fractillus has a spell for knocking back players that get too close to him (called the

, funnily enough), and that ability captures an event in the logs if you are immune (e.g. bubble). We were able to use those events and other nearby events to estimate a new boss position, and once we entered that into the code, everything fell into place and the lane matching worked like a charm!

After a bit of cleanup reviewing additional logs/vods to tweak the lanes and make sure we were matching all edge cases properly, we were able to roll this feature out to everyone on Wipefest."
