Golden Survival Rules

MP Restoration Trick: whenever your magic pool runs dry during exploration, awaken or level up any Parasite Energy in the menu to instantly restore 100% of Aya's MP.
Support PE Priority: prioritize leveling Metabolism (removes and prevents status ailments), Healing (vitality recovery), Antibody (reduces damage taken), and Energyshot (weapon damage multiplier).
Best early offensive PE is Necrosis: deals heavy elemental damage and inflicts continuous poison, permanently breaking optical camouflage on stealth mutants.
Never consume [???] Relics directly: always keep Holy Water, Skull Crystal, Ofuda, and Medicine Wheel slotted in your armor for permanent passive stat multipliers.
M.I.S.T. Shooting Range: clear all 5 target training challenges with Pierce before leaving Los Angeles to claim 50 Hydra rounds, Ringer Solution, Hunter Goggles, Lipstick, and the Shoulder Holster from Jodie.
