Changelog
The changelog was taken from here.

DEATH THE DUNGEON MASTER

 * Death is no more. All hail Jeohnne Pierre, our great Dungeon Master!
 * Death's AI received a massive overhaul and its tier moved from pre-mech to post-golem. I mean Dungeon Master's AI. You get it.
 * Dungeon Master's HP changed from 9999 to 66666, defenes changed from 18 to 44.
 * Dungeon Master's physical damage changed from 50 to 99, projectile damage changed from 40 to 66.
 * Bloody Skull item removed. New summon item craftable from Ectoplasm. Vampire Blood and Souls of Night requirements reduced from 6 to 3.

DEATH'S GEARS

 * Death's Scythe completelly reworked to not be just a glorified sword but a fancy and unique chargeable weapon. Death's Scythe recipe simplified to only require Obscure Essences. Material requirement reduced from 40 to 15 to fall in line with other similar recipes. It also has a new sprite (contributed by Suweeka).
 * New chargeable bow with extra piercing on full charge.
 * New chargeable spellbook shooting tiny or giant death sickles.
 * New generalist armor set granting below average damage to all types but a powerful risk-reward set bonus.

UMBRELLAS AND FAIRIES

 * Craftable Suspicious Umbrella to increase global spawn rates, alongside greatly increasing spawn rates of fairies and similar enemies.
 * Power Ups can now be used to provide a constant buff when used, consuming Power Ups over time for extra damage.
 * New Hotkey to automatically toggle the Power Up buff.
 * Koumajou Set renamed to Youkai Hunter, now a throwing-centered armor set providing reduced Power Up costs.
 * Rumia's vanity set renamed to Dark Child set, now providing extra defense, damage reduction, blindness and enemy-sense when powered up.
 * Forest Fairies
 * Ice Fairies
 * Underground Fairies (Zombie Fairies)
 * Hallowed Fairies (Holy Fairies) (also fancy sword projectile contributed by puffepuf)
 * Evil Fairies (Cursed Fairies)
 * UFOs! (kinda placeholdery)
 * Youkai Repellent Charm's type changed from magic to throwing. Damage increased from 9 to 12. Now consumes Power Ups as ammo. Can consume extra Power Ups for a special attack.
 * Youkai Buster now cosumes Power Ups as ammo and can consume extra Power Ups for a special attack. The type will not be altered for the time being due to the lack of hardmode throwing gears, however it no longer requires mana to be used.
 * Recipe requirements adjusted to fit the new Power Up system and drop rates. Dark Child's set recipe changed to now require Shadow Scales/Tissue Samples. Youkai Buster recipe adjusted to require 20 Crystal Shards instead of 50.
 * Rumia's spawn chances are affected by the umbrella and base spawn chance was slighly lowered to compensate. Her sprite was also slighly improved (by Suweeka).

Item Adjustements and Fixes AKA the 'Ivy Plant didn't even spawn' UPDATE

 * Increased damage of Sandman from 8 to 10. The baseball now deals full weapon damage instead of half.
 * Reworked charge system of Chick Decapitator and Red Wing to allow for prefixes to work properly.

 * New sprite for Starstorm's projectiles and Soma (contributed by @Suweeka).
 * New unique sprites for Dungeon Master, Ivy Plant, Ardorix, Arborix and Aquatix's expert mode bags (contributed by Suweeka).
 * Renamed Thick Gel into Metroid Membrane because it sounds more straight forward and less... weird.
 * Renamed Thick Paper into Paper because... not even I know the story behind that one.
 * All item prices should now be as intended. Please report overly ridiculous price tags in case I missed anything.
 * The recipe for the Jump Pack has been removed as the item is currently not functional.
