Changelog August 6th

Details

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 the punishment 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 Doom’s health bar.
Unclaimed loot can now be retrieved from a chest in the lobby if you leave after pressing 'Claim and Leave'. The loot interface can also be accessed from further away.
Made the charged attack particles smaller to reduce the chance of misclicks.
Improved the Doom’s 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 its beam charge 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 above effects will now also occur if the boss is killed with the bonus damage from the melee punish.

Reduced the chance of back-to-back rock-throw attacks.
Grubs now try to spawn farther away from the boss (but still on the same side as the player).
Melee grubs no longer spawn outside of the shield phase.
Added an extra tick (0.6s) before the charge beam fires to give players more breathing room to deal with multiple attacks.
Improved the visibility of the Doom of Mokhaiotl’s melee projectile by using a deeper red colour, matching the one used for Leviathan.
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 waves 1-2 and 1/50 for later waves.

Varlamore Changes

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.
Custodian Stalkers now correctly appear in Slayer level-up messages instead of Jellies.
The Orange hat is now storable in the PoH.
Highlighting the Gemstone Crab's shell will no longer highlight random spiky shapes outside of the shell.
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.
The Wardens’ skull bombs can no longer land underneath the Obelisk.
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 Accursed Sceptre (a) can now correctly use its special attack without setting an autocast.
Combat stat adjustments:

Dragons’ Stab defence lowered to 0, from 5.
TzHaar are now correctly 40% weak to Water spells.
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.

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.

The first option on placeholders in the Seed Vault is now correctly labelled as Remove-placeholder.
The Geomancy spell interface no longer incorrectly displays the Tai Bwo Wannai Calquat patch or the Draynor Manor Belladonna patch.
The ‘Investigate’ option on the smashed window in Sinclair Mansion during King’s Ransom now correctly reflects whether it is broken or repaired.

Delve Boss Changes

We’ve been having a ball watching you dive into Delve, push its limits, and share your feedback. There’s been a lot of great discussion over the past week, and it’s helped shape some of the improvements you’ll 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 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.

Made the charged attack particles smaller to reduce the chance of misclicks.
Improved the Doom’s 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.

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.

Nieve is waiting for you at the Grand Tree!

If you can’t see the image above, click here!

Not even the afterlife could keep Nieve from her Youtooz debut! Standing at 4.8 inches tall with long blonde hair, she holds her iconic Zamorakian Hasta in her right hand and a translucent Elysian Spirit Shield in the other. Her outfit is completed with a Fire Cape hanging from her shoulders and an Amulet of Fury around her neck along with full Bandos Armour.

Who got the King Black Dragon fired up?

If you can’t see the image above, click here!

The King Black Dragon may be bored after thousands of years of battles but we’ve 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!

Pre-order now here!
