Converting PF1 Spells to Starfinder First Edition: Absorb Toxicity (Patreon)

I've done a lot of these, but not for a long time. Paying patrons can find a continuously updated page with all of them here, and the index for all Starfinder First Edition articles here.

Absorb Toxicity
Classes mystic 3, witchwarper 4
School necromancy
Casting Time 1 standard action
Range personal
Duration 10 minutes/level or until discharged
Saving Throw see text; Spell Resistance no

You absorb the toxicity of your surroundings, becoming toxic as a result. While under the effect of this spell, you are immune to diseases, poisons, and radiation with which you come into contact. When you are exposed to a disease, poison, or radiation effect, you can choose to absorb it. Doing so ends the immunity due to this spell to any disease, poison, or radiation effect other than the one you absorbed. You remain immune to the new affliction until this spell ends. Casting absorb toxicity a second time does not allow you to absorb a second toxin, but instead resets the duration of the effect to its full 10 minutes/level.

While you have an affliction absorbed, you can use a melee touch attack to transfer that affliction to another creature. A missed attack does not discharge the spell, and you can try to transfer the affliction again in subsequent rounds. If you hit, this spell is discharged, and your target must make a saving throw against the transferred affliction (DC equal to this spell’s save DC or the affliction’s save DC, whichever is higher) or suffer its effect or initial effect immediately. The target then continues to suffer from the affliction’s normal effects.

If the spell’s duration expires before you have transferred the affliction, you are exposed to any absorbed disease, poison, or radiation as if you had transferred it to yourself, but you gain a +2 bonus on saves against that particular instance of the affliction. Absorbing an affliction does not end an affliction from an ongoing source, such as an area of radiation, or a monster's poisonous attack.

(Congratulations. You're toxic. Art by grandfailure.)
