Editing Blackstaff's Tome of Wizardry (section)

==The Green Star Adept==
A blast from the past, the Green Star Adept first appeared in the Complete Arcane as a [[gish]]-themed prestige class that slowly transformed the character into a living golem of luminescent green "star-metal". It was widely considered terrible. This subclass is basically a 5eification of that original prestige class, and preserves the original concept: you're a wizard who seeks to fundamentally empower yourself with magical energy by ingesting alchemical formulas based around the viridian-hued star-metal left behind by the Green Star of Alhazarde.

At level 2, the Green Star Adept first begins consuming their '''Green Star Admixture''', which makes their unarmored AC equal 13 + Dexterity modifier and causes their unarmed attacks to deal 1d4 damage.  This damage increases to 1d6 at 6th level, 1d8 at 10th level, and finally 1d10 at 18th level. They also gain the feature '''Star Expert''' at this level, which gives them Advantage on any Intelligence check relating to the sky, as well as the ability to cast Dim Light in a radius of 5 feet from the green crystal-like slivers of star-metal growing from their flesh.

At level 6, the advancing transmutation of their body gives them '''Jade Skin'''; they can now add their Intelligence modifier to Strength and Constitution saves, and get to make a Constitution save (DC equal to the modified damage) against critical hits; if successful, they downgrade the critical hit back to a normal hit.

By level 10, the transmutation of their body has turned them into a living '''Arcane Focus'''; they always count as having a spellcasting focus, and spells with a range of "melee" gain bonus damage equal to the Green Star Adept's unarmed attack damage. Also, once per short rest, they can cast a "self" targeting spell with a +1 spell slot level bonus - that is, they can cast, say, a level 3 spell with the potency of a level 4 spell without having to actually use a level 4 spell slot to do it.

Finally, by level 14, the Green Star Adept has attained '''Emerald Perfection''', gaining a sizable list of [[golem]]-like powers: they no longer need to eat, drink, breathe or sleep, and are immune to poison damage, disease, and exhaustion. They're also impervious to the Deafened, Incapacitated, Petrified, Poisoned, Stunned and Unconscious conditions.
