[2023] Necromancy Prayer.

Other than the fact that the prayer is deemed as a 'curse', I don't think it can be sloppily added to the Praesul codex after the fact just for the sake of it.

I'm well aware that the final Necromancy boss will drop tier 95 armour, but this could potentially be the drop from the lower tier Necro boss split amongst pages where it requires x amount of pages to complete (similar to Dominion journal).

Mid tier Necromancy boss could drop untradeable pages of the Codex, called:

• 'Tainted page' - a tainted page torn from an old Codex.
  

Five or Ten of these pages could be combined to make the codex, potential options:

• 'Lost Praesul Codex' - one of the first Necromatic codex's written in the City of Um.

• 'Stolen Praesul Codex' - a codex stolen from Nex, tainted with the incantations of the first Necromancer.

Which can be tied into the lore about the boss, lore about the City of Um or the past Necromancers who habited the City of Um. There's a lot of potential lore areas that can benefit from this.

Also gives the player a sense of achievement to unlock this prestigious upgrade alongside the players journey through their Necromatic adventures to skill mastery.
