We know last week’s changelog felt a little light for some, especially following such a big launch. Much of what we focused on early was under the hood – important stuff, just not the kind that grabs attention in a blog post. This week’s update builds on that foundation, and we think the changes will be a lot more noticeable.
However, we’re being mindful about how much we change and how quickly. The Doom of Mokhaiotl is designed to be a tough, endgame-level boss, and we’re happy with the overall level of challenge it offers. Our goal is to refine the encounter without losing what makes it demanding and rewarding.
There are still a few areas we’re actively discussing, and just because something didn’t make it in this week doesn’t mean it’s off the radar. We’ll keep reviewing how things are playing out and continue listening as more of you take on the fight.
Here’s what’s new this week:
- The melee punish phase now ignores attack delay if the player is using melee.
- Added a sparkly glow to the burrow hole when a unique item is present.
- Replaced triple grub spawns with a single giant grub that has double the health, explodes in a larger area, and causes triple the punishment if it reaches the boss.
