Initial Drop:
A book "archive" that unlocks "Master Void Equipment" knowledge (as well as a teleport straight to raids 4).
1kc drop-has lore inside it to read.
Additional drops:
Med Tier Upgrades:
Cloth upgrade to allow void gloves to combine with barrows gloves OR slayer bracelets (pick either one here, both useful upgrades).
Visor/Bracket Upgrade to allow combination of the void melee helmet with slayer helm or serpentine helm (pick either one here, both useful upgrades).
New trade-able Void Knight armor AND weapon ornament kits in a Guthixian green.
Lore:
This can be "Some of the hidden knowledge kept deep within the archives, long forgotten by Masters of the Void Knights AKA the first to get together before the knights officially formed."
Higher Tier Upgrades:
Mega rare: Void Knight Mace Upgrade
Void Knight mace upgrade suggestion details:
Name: The Enforcer
Utilizes an unused item
Passive effect to cause a "crushing blow" similar to the keris passive on kalphites except it would act as a passive for any mob.
(It is a mega rare after all).
Passive deals Flat damage of 100.
Passive procs increase with completion of elite diaries, similar to zcb spec.
Armor sidegrade: Master Void Knight top/bottom
Adds a +2 prayer bonus for both
Adds a +10 accuracy to crush for both
(Pairs well with the new megarare).
Void Knight Necklace: The Annihilator
Adds a +2 prayer bonus
Adds a +10 accuracy to crush
Upgraded from dragonbone necklace
All of these are "Crush related upgrades" available to existing lore-based equipment and gear that most players going into raids 4 should already have to "upgrade".
Keep it simple-utilize what's already in the game with a few additions to existing.
(Notice this in NO WAY buffs range, or Magic and only slightly buffs Melee, as well as crush accuracy, while fixing glove and helmet problem areas of void).
