Version 8.4:

Updated to Quest Items Resized version 1.4.
Automatoi Champions at Knossos Palace no longer keep spamming Energy Shield on themselves.
Heat Shield and Energy Shield now reserve 75 energy, down from 100.
Fixed the Arc of Attack bug for Rend Armor (Defense) and Spreading Influence (Neidan): Rend Armor now always has a static 120 degree Arc of Attack, and Spreading Influence now scales from 15 to 90 degrees (Which is actually 180 degrees, the highest you can get before it starts looping backwards. For more info, see this graph which shows the difference between the displayed values and what you get in reality due to the bug: https://i.imgur.com/yMCBPYN.png)

Version 8.3:

Increased Core Dweller's base energy regeneration from 2.0 to 3.0, and optimized its taunt aura.

New "Unlock Content" codes are available:

"123" - Gives you a selection of helpful potions to use when things feel unfair. Note that some of these potions cannot be picked up without the Eternal Embers expansion.
"1234567890" - Gives you a potion to respec your attribute points.

Note that these codes can only be used once, so don't waste them.

Version 8.2:

The heroes Lysia Spellbreaker and Miao Miao can now only cast Energy Shield with the Reflection modifier on themselves.
The automatoi champions outside Knossos Palace can now cast Energy Shield as intended, but only on themselves. The "Masterwork" versions at Olympus retain the AoE version of the shield.
The restored Spirit Animal and Dream Guide enemy summons from A Few Bug Fixes now have the correct levels on Epic and Legendary difficulty. In addition, the Dream Guide has been rebalanced, and its mana burn has been nerfed from 65% to 20% per cast.

Version 8.1:

Fixed a bug that prevented the XP adjustments from working as intended after a recent update.
The Might of Hephaestus set (mace, shield, ring) now has +15.0 energy regeneration and -15% recharge on its set bonus. When combined with the artifact by the same name (Might of Hephaestus), this allows you to use Ring of Flame permanently. Juggernauts don't have any other sets than this one from core TQ, so I thought I'd give it some love and make a Hephaestus character build a bit more fun.

Version 8.0:

The Core Dweller pet now has 100% bleed resistance and 50% life and energy leech resistance. (It already had 100% vitality and poison resist)
Fixed its bugged skill which was supposed to give it a chance to stun on melee hits. It's also slightly better at keeping enemies' attention.
Its "Wildfire" skill now does fire damage instead of burn damage, allowing it to stack with other sources of burn damage, and it now slows enemy movement speed by up to 20%.
The Nymph's "Overgrowth" shield now heals the target for half of the amount absorbed, and does slightly more pierce damage.
Heat Shield, Energy Shield, Herbal Remedy and Rune of Life are now toggled skills with a 20 meter radius. In return, they now reserve mana. This also means that items which grant these skills can no longer be abused by unequipping them after applying the buff.

Version 7.12:

Nerfed the life leech/energy leech AoE used by Soul Empusas and other mobs. It was massively overtuned as it didn't account for AE level scaling, and it remains very strong but now it's at least possible to have energy left after being in it for 1 second with 80% energy leech resistance.
Added various minor bug fixes.

Version 7.11:

Rebalanced Herbal Remedy from Hunting. It now provides less % Health Regeneration in the beginning but scales up to 100%, making it less overpowered early game and more powerful late game. The poison resistance now scales from 30% to 100% like vanilla, except it scales more linearly.
Reduced the energy drain on the huge energy drain aura from Draugr Princes in Ragnarok by 50%.
The armor pieces from The Shade set now only require 50 strength so that casters who want to use the staff don't have to invest in strength to equip the full set.
Made some minor tweaks to the crab pets from the Atlantis rings.

Version 7.10:

The first boss of Atlantis now spawns the unused higher level variant present in the game files. Due to his unconventional spawn method where he rises out of a tomb, it is not possible to spawn several of him, so spawning his slightly stronger variant is the best we can do.
The crustacean pets from the Atlantis rings have been overhauled with many improvements and are now as tough as they look.

Version 7.9:

Awesome Artifacts update:
The temporary pets from Star of Ishtar and Sigil of Bast now have Aggressive AIs.
Reduced the run speed bonus on the proc from Crescent Moon of Artemis to +50% speed, but it now ignores the movement speed cap.

Version 7.8:

The version of Deathchill Aura provided by The Shade set no longer drains energy and cannot be dispelled. This fixes a bug where it would become permanently disabled.
Shield of the Shades now has a base block recharge time of 2.0, down from 2.5.
