IEH2 [ver. 4.1.5.1] Auto Area/Dungeon Progression Loadouts!

Added [Auto Area/Dungeon Progression Loadouts] to the Epic Store’s Ambition 4 tab. Save and switch between progression settings and target clear counts. The first purchase unlocks 2 slots for both AAP and ADP; each additional purchase adds 1 slot, up to 5. Shift-click a loadout button to rename it. Loadouts carry over between WA3 Runs.
Added a “Go to Favorite Area when finished” option to Auto Area/Dungeon Progression. When enabled, participating heroes return to their Favorite Areas after progression ends. When transitioning from AAP to ADP, heroes not joining ADP return to their Favorite Areas. These settings are saved in loadouts and carried over between WA3 runs.
Background Mode now displays the Tier 3 World Ascension count. During WA3 runs, it also shows expected Heart Stone and Spirit Essence rewards alongside your current balances.
Buffed Treasure Instinct’s Lv35 passive: Rare Artifacts are now always included in its equipment reward pool, without requiring a separate Artifact drop chance roll.
The Cloud Save success popup now displays a 10-second countdown and closes automatically. The countdown scales with Nitro Speed.
To address severe performance drops caused by Counter-triggered projectile bursts, Base Attacks triggered by Counters no longer activate the additional attacks from Bananoon Doll or Florzporb Doll. Regular Base Attacks still trigger these effects.
Fixed a bug where auto-disassembling artifacts through enchantment filters did not apply Piece of Ruby gain bonuses.
Fixed a bug where Auto Mysterious Water Adder remained unavailable until the World Ascension 1 screen was opened, even when its unlock requirements were met.
Fixed custom Multibuy values resetting to defaults after a WA3 Retry.

Added Steam leaderboards for the highest Area Mission, Pet Rank, Super Dungeon Modifier, Expedition, and Nitro Reactor Milestones reached in Main. WA3 Run progress is excluded.
When Blue Treant’s pet active effect is enabled, acquiring Relic [Expedition Timer Counter] now automatically claims completed expeditions and starts eligible expeditions before applying its time advancement effect.
Spirit Essence Gain passives now remain active while the Dormant Relics fracture is enabled.
Changed Treasure Instinct’s Lv35 passive: Equipment granted by this Relic, including at the start of WA3 Runs, now has a chance to include Rare Artifacts.
Fixed WA3 Auto Retry freezing when exiting Background Mode during the retry countdown. The countdown now resumes with the remaining time preserved.

Relic Echo’s bonus stacks now accumulate with consecutive picks and are applied together to the next non-Echo Relic you select.
Area Mission Milestone #5000 now also increases the level caps of Super Adventuring, Super Developing, Super Hunting, and Super Experimenting from 20 to 100.
Reduced the level-up cost of these four Guild Super Abilities from [5 + 5 × Lv] to [1 + Lv]. The difference for previously purchased levels will be automatically refunded as Guild Super Ability Points when the save is loaded.
General Upgrade levels now carry over between WA3 Runs when both WA3 Accomplishment #35 and Area Mission Milestone #4000 have been achieved. Fracture [Primitive Upgrades] disables Resource Gain 2+ effects while preserving their levels for future Runs without the Fracture.
SD Modifier Milestone instant-clear rewards now apply at the start of WA3 Runs when WA3 Accomplishment #95 and the corresponding milestone have been achieved.
Ultimate Trial [Monty Punching Bag] is now exempt from No Second Chances and no longer ends your WA3 Run when the trial ends or you quit it.
Relic [Relic Echo]’s bonus stacks now work with Fracture [Relic Singularity], applying to the next selected stackable Relic.
Fixed an issue where WA3 Accomplishment progress could be lost after performing WA1 or WA2 and restarting the game during the same WA3 Run.
Fixed WA3 Auto Retry not working in Background Mode. Automatic retries now keep Background Mode active and respect the Nitro countdown speed setting.

Fixed Auto Area Progression stopping prematurely at locked regions while Purple Magicslime’s active effect is enabled. Cartographer now immediately levels up as far as available materials and its level cap allow, then progression continues if the region is unlocked.
Fixed inherited Quest rewards granting Dungeon Coins again when the Coin balance was already carried over from the previous WA3 Run.
Fixed Ordeal 26 completion record being lost, preventing progression to Ordeal 27 and beyond. Players who previously completed Ordeal 26 will need to complete it again after this patch.
Fixed the Raid Boss Quit button not working correctly when a different Hero was selected in Challenge Easy Access.
Fixed an issue where the Super Dungeon Quit button failed to exit when a different Hero was selected in Challenge Easy Access.
Fixed the Super Dungeon auto-purchase floor limit resetting to 100 between WA3 Runs despite having unlocked WA3 Accomp #95.

New Epic Store Item [Nitro Reactor Loadout] in QoL5 tab
Added quick-access reset buttons. If a Reset Item’s cost is 0 Epic Coins due to the effect of Reset Bundle, a dedicated button will now appear in the relevant UI, allowing you to reset it instantly without opening the Epic Store. (Excepts for WA1/2 Upgrade Reset.) For example, if [Guild Ability Reset] costs 0 Epic Coins, a dedicated reset button will appear in the Guild tab.
Changes
Nitro Reactor can now be accessed after World Ascension if it has been unlocked at least once through Town [Adventuring Party] Rank 3 ⁠
Epic Store item [Tier 2 World Ascension Upgrade Reset] now also performs a reset equivalent to Tier 2 World Ascension without gaining points from current progress.
Bug Fixes
Fixed an issue where performing WA1 after resetting WA2 Upgrade [Tier 1 Milestone Expansion] via Epic Store [Tier 2 World Ascension Upgrade Reset] could reduce the Best Lv of WA1 Milestones that were originally Lv11+ back down to Lv10.
Fixed an issue where using Epic Store [Nitro Reactor Rank Reset] could duplicate Nitro Reactor Points. As a result, after this patch, performing Nitro Reactor Rank Reset will correct Nitro Reactor Points to their proper value.
Fixed: General Quest [Tiger Taming]'s captured count is now correct
Fixed: Other minor bugs/typos
Hello everyone! Thank you all so much for your continued support and feedback. I really appreciate it!
I’ve been working on implementing Tier 3 World Ascension for the next major update. It’s coming along, but it’s taking a bit more time than expected. So I decided to release a patch focused on fixes and QoL improvements first.
After that, I’ll be fully focusing again on finishing the WA3! I’m really excited to share it with you all!

Full Patch Note: IEH2 [ver. 3.1.3.1]
Additions

Bug Fixes
Idle Mode calculations are now more accurate.

Idle Mode (Performance Optimization)
The game will enter Idle Mode after 30 seconds of no player input.
Idle Mode is applied only to normal areas and dungeons.
Super Dungeons and Challenges are excluded and will continue to run normally.
Idle Mode is applied only when the area clear time is less than 1 second in real-time.
Areas that take 1 second or longer to clear will continue to run standard battle updates as usual.
Idle Mode is also applied during Auto World Ascension and Auto Rebirth.
How Idle Mode Works
In Idle Mode, Battles for Passive Heroes are fully calculated through simulation rather than running the standard Battle Update loop.
This significantly reduces CPU load.
For example, when all 6 Heroes are set to Active/Passive:
The 5 Passive Heroes will switch to simulation-based Battle processing.
As a result, the Battle processing load is theoretically reduced to approximately 1/6.
Overall, this results in up to around a 50% reduction in total CPU usage for the game.
While in Idle Mode, EXP, Gold, Resources, Materials, Equipment, Capture #, Defeat #, Skill Trigger #, Area Clear Count, etc will continue to be gained normally.
Background Mode Improvements
In Background Mode, not only Passive Heroes but also the Active Hero will be fully simulated.
This results in a dramatic improvement in overall game performance while running in the background.
Others
Added: "Common Talisman Gain from Swarms + X%" at Town [Cartographer] Lv Milestone Lv90-100 and AMM5250, 6250, 7250.
Added: Talisman [Nari Sune Doll] extra passive effect "Talisman Fragment Gain +%"
Added: A new option "Disable Auto SD during Auto Tier Switching" in Rebirth > Auto RB Customize > Auto Tier Switching Settings
Changed: Rebirth Point Gain from Town [Temple] is now multiplicative
Fixed a bug where Passive Heroes could become stuck inside a Dungeon when WA was performed during Auto Dungeon Progression. With this patch, if WA is executed while ADP is in progress, all heroes will move to their Favorite Area after WA. (If "AAP on WA" is enabled, AAP will be executed.)
Fixed: Other minor bugs
Thank you for always supporting IEH2!
This has been one of the biggest optimization updates so far, and it was made possible thanks to the community’s feedback and testing.
I would especially like to thank everyone who participated in the beta test on our Discord. Your help and reports were incredibly valuable. Your support truly means a lot.
I hope you enjoy the smoother performance!

Improved: Export/Import File dialog now remembers the last used folder. The save and load window will now open in the previously selected location instead of defaulting to the C: drive each time.
Added: Current total pet rank after WA2 now shows in Bestiary
Fixed: Auto Area/Dungeon Progression could get stuck when changing Area Difficulty during progression.

New strategies.
New growth ceilings.
New possibilities.
