The initial Patch 7.31 shipped with a few internal item changes that were not supposed to be shipped to the public.

The new items included the return of Diffusal Blade II and 3 other new items (all of them are Eaglesong upgrades).

These changes were already reverted by a follow-up update 1h afterwards, but I managed to document the internal items anyway.

Price: 5500 gold

Recipe: Diffusal Blade I + Eaglesong + Recipe (200g)

Stats: 45 Agility, 15 Intelligence

Manaburn Passive: 50 mana (hero), 16 mana (illusion melee), 10 mana (illusion ranged)

Active: Purge (functions like old Diffusal Blade II)

Cooldown: 15 seconds

Does not use charges like the old Diffusal Blade II, uses a regular 15 seconds cooldown. Purges and applies a decaying slow on the target. Cannot target invulnerable (cycloned) units.

Price: 3700 gold

Recipe: Gem of True Sight + Eaglesong

Stats: 35 Agility

True Sight (Passive): same passive as Gem

Everlasting (Passive): Item cannot be dropped once equipped (like Aegis). Item is disassembled on death and the Gem is dropped on the ground. (example video)

Predator’s Gaze (Active): Reveals a 300 area within 1500 range for 6 seconds. (works like Seer Stone active)

Cooldown: 30 seconds

Voidwalker Scythe:

Video: https://youtu.be/HSiRruvljMY

Price: 3900 gold

Recipe: Javelin + Eaglesong

Stats: 40 Agility

Swift Strike (Passive): Every 4th outgoing attack deals 300 bonus magical(?) damage (has true strike).

Void Shift (Passive): Every 4th incoming attack causes you to become untargetable for 1 second. (works similar to Shadow Realm)

Evaded attacks do not count towards Void Shift’s incoming attack counter.

Fluff: This is the only new item that has the following (placeholder) lore: „Lore lore lorem ipsum.“

This might suggest that it was the closest one to actually being implemented, other than Diff Blade II of course.

Bruiser’s Maul:

Video: https://youtu.be/BQp5smyaDrk

Price: 6100 gold

Recipe: Basher + Eaglesong

Stats: 35 Agility, 15 Strength, 30 Attack Damage

Bash (Passive): identical to basher’s passive

Tenderise (Passive): Every attack on the enemy will reduce their total attack speed by 5%. Lasts 3 seconds.

Internal Name: Tenderizer

Unmentioned behaviour: The Tenderise debuff apparently fully stacks with itself and a new stack resets the debuff duration to the full 3 seconds for all stacks.
