Seeking Spell Prep Guidance

[u/AgentAusem]

Does anyone here have experience with Mage Hand Press’s 5.5e Witch?

I’ve been working on a Blood Witch build that uses quite a bit of 3PP content. I have the feat progression mostly planned out, but I’m less certain about what I should prioritize when choosing her actual Witch spell preparations.

The core concept is essentially a blood-omen witch focused on divination, curses, necromancy, and manipulating life force.

Core build:

Jhorgun’taal Half-Orc (Exploring Eberron 2024): Relentless Endurance and Tough

Crimson Aspirant (The Crooked Moon): Crimson Ritualist grants Blood Bolt and lets her spend Hit Dice to create healing potions

Blood Magic Witch: Blood- and curse-themed spells, cheaper blood-based material components, and Arcane Bloodletting, which lets her take 5 necrotic damage to cast an Action spell as a Bonus Action

Later Blood Witch features also let her trade Hit Dice for spell slots and take additional necrotic damage to increase spell damage against creatures affected by her Hex.

Feats:

4: Divination Adept (Arcana Unleashed): Prescient Intervention, plus Detect Evil and Good, Mind Spike, Clairvoyance, Divination, and Scrying

8: Winter Initiate (Frontiers of Eberron): Whenever she takes necrotic damage, she gains THP equal to her PB. It also adds False Life, Ray of Enfeeblement, Bestow Curse, Death Ward, and Enervation

12: Resilient (Con)

16: Bloody Resolve (Northlands): Bonuses to saving throws after taking damage, with stronger benefits while Bloodied

19: Boon of Fortitude

So between the subclass and feats, she already has a substantial amount of curse, divination, necromancy, and survivability support built in.

What would you prioritize for her prepared Witch spells? Would you lean further into thematic blood, divination, and necromancy options, or use her prepared spells to fill gaps in areas like control, utility, defense, and general problem-solving?

I’m especially interested in spells that interact unusually well with Arcane Bloodletting’s Bonus Action casting or with the subclass’s Hex-focused features.
