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. (
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:
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:
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
