Varlamore & Summer Sweep-Up Combat Tweaks

Posted by on 06 Aug 2025

Known Issues	Status
Midair projectiles during Dooms melee punish phase can trigger a phase transition and cause unintended healing.	Hotfixed. Dooms transition to shielded phase is now triggered by his attack timer instead of on-hit. To avoid instant phase transitions, he will also wait for 2 attacks after the last orb phase before triggering the shield. Additionally, Doom can no longer heal unintentionally after firing his beam.
Re-equipping Lightbearer at the Delve boss allows for the regain of Special Attack.	Hotfixed.
The large grub spawned at the Delve boss does not have its expected 1 tick attack delay after it has been killed.	Hotfixed.
The Holy Water boss effect isn't guaranteed when killing the boss during the melee punish phase.	Hotfixed.
Beam charge during the melee punish phase can no longer be interrupted by grub damage - this should prevent Doom from starting a melee punish and unexpectedly switching to the blue shield phase a few ticks later. Note: if you have an arrow in mid air and it knocks the boss past its 75% threshold - this will still cancel the punish and move it onto the blue hp phase. This is intended.	Hotfixed.
Surviving Grubs no longer de-spawn and persist into the car phase.	Hotfixed.
Players can drink surge potions in between delve levels.	Hotfixed.
Gemstone Crab MVP announcement celebrates "null" if the MVPs are logged out of the world at despawn.	Hotfixed.
Giant grubs don't stall like the small grubs do when KO damage is incoming.	Hotfixed.
When transitioning from Melee Punish to the Blue Shield Phase, some subsequent orb projectile attacks are being nullified.	Hotfixed.
Grubs spawning in at Doom have an expanded clickbox that will sometimes overlap with Volatile Earth.	Hotfixed.
The Doom boss's hitbox can be extended after a diagonal wall dash during the car phase, allowing the charge to hit players even when they are far from the boss.	Investigating.
Rocks that spawn on acid before the car phase are deleted.	Investigating.
Grubs spawning in have an expanded clickbox that can sometimes overlap with Volatile Earth.	Investigating.

This week brings continued improvements to Varlamore and the Delve boss, with added combat tweaks from the Summer Sweep-Up.

Changelog August 6th

Doom of Mokhaiotl Changes

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 punishment to the player if it reaches the boss.
Rockfalls no longer place a permanent rock on your position if you are hit by it while under the protection of the shield orb.
The centre tile of the shield orb now clears acid as it moves.
The current Delve level now appears in Dooms health bar.

Made the charged attack particles smaller to reduce the chance of misclicks.
Improved the Dooms clickbox to prevent players accidentally clicking through the boss.
The Holy Water item now correctly one-shots range larva spawns during the fight.
The Holy Water effect triggered upon killing the boss can now be activated by the bonus damage dealt from the melee punish, not just the primary damage splat.
Special attack energy no longer regenerates between Delve levels, during loot collection or downtime between fights.
Killing the Doom of Mokhaiotl during the Melee punish phase will now heal up to 24 Prayer Points, 32 HP and 25% special attack energy regardless of where you're standing. This will also clear acid in a 3x3 area, centred around water projectiles landing on the ground after the boss has died.

The Eye of Ayak now instantly kills magic grubs and ignores attack delay.
Cannons can no longer be placed in any Delve level.
Added Elite clue scrolls to the loot table, with a drop rate of 1/75 for Delve levels 1-2 and 1/50 for later delves.

Vale Totems now correctly count toward the total minigame items in the Collection Log overview instead of the Other total.

Custodian Stalkers now correctly appear in Slayer level-up messages instead of Jellies.

Adjusted the reclaim cost and PvP drop of the Arkan Blade from 75,000 to 250,000 GP to more accurately account for its power.

Summer Sweep Up Combat Changes

There is now a warning message when depositing Inventory or worn equipment in the deposit pot in TOA.

Further refined Zebak's waves to stop the player from getting pushed closer to Zebak while attacking.
Duke mushrooms and salts now stack properly if your Inventory is full and you have one held.

The Giant Mole is now 50% weak to Earth instead of Water.

Fixed a graphical issue where the Crondis crocodiles would sporadically turn towards the player when pathing to the tree.
Reduced the number of tornadoes spawned by the Blue Moon as our last change didnt have a significant impact - let us know how this feels!
Halberds can now do damage to Vespula when flying.
Decreased Ironman's minimum damage threshold from 10% to 7% for group Wilderness bosses.
There is now a quick leave option while fighting Bryophyta and Obor.

Delve Boss Changes

Weve been having a ball watching you dive into Delve, push its limits, and share your feedback. Theres been a lot of great discussion over the past week, and its helped shape some of the improvements youll see today. That includes tweaks to the melee punish phase, adjustments to grub behaviour, better clarity during certain mechanics, and a range of smaller fixes that should make the overall experience feel a bit tidier.

We know last weeks 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 weeks update builds on that foundation, and we think the changes will be a lot more noticeable.

However, were being mindful about how much we change and how quickly. The Doom of Mokhaiotl is designed to be a tough, endgame-level boss, and were 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 were actively discussing, and just because something didnt make it in this week doesnt mean its off the radar. Well keep reviewing how things are playing out and continue listening as more of you take on the fight.

Heres whats 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 punishment to the player if it reaches the boss

The Holy Water item now correctly one-shots range larva spawns during the fight.
The Holy Water effect triggered upon killing the boss can now be activated by the bonus damage dealt from the melee punish, not just the primary damage splat.

Varlamore Changes:

While the Doom rages below, things have been ticking along nicely back on the surface. Here are a few more Varlamore updates:

Vale Totems now correctly count toward the total minigame items in the Collection Log overview instead of the Other total.
The Proudspire Agility shortcuts now show up correctly in Agility level-up messages.
Using the Eye of Ayak's special attack no longer causes the clickbox to change.

Not even the afterlife could keep Nieve from her Youtooz debut!

The King Black Dragon may be bored after thousands of years of battles but weve managed to pique his interest with a Youtooz debut! At 4.1 inches tall his bright red eyes shine out from above his three toothy, horned heads. A pair of jagged wings curl out from his shoulders as a long thick tail wraps around his back and clawed feet. Scary stuff!
