Consumable items are your lifeline in Tartarus, providing healing, SP recovery, and status ailment cures. Stocking up on these before each expedition is crucial. They can be purchased from the pharmacy, vending machines, or found in Tartarus.

Key Item Categories:
- Healing Items: Restores HP (e.g., Medicine, Snuff Soul).
- SP Recovery Items: Restores SP (e.g., Soul Drop, Chewing Soul). These are often the most valuable.
- Status Cure Items: Cures specific status ailments (e.g., Dis-Poison, Dis-Charm).
- Battle Items: Deals elemental damage or inflicts status ailments (e.g., Fire Gem, Ice Gem). Useful for exploiting weaknesses when your Personas lack the right skills.
- Revival Items: Revives a fallen ally (e.g., Revival Bead, Balm of Life).
Prioritize SP recovery items, as SP is often the limiting factor in long Tartarus runs. Don't be afraid to use items during boss fights; that's what they're for!
