Acid Splash 2e FAQ FAQ
Did Acid Splash exist in AD&D 2nd Edition?
No. Acid Splash was not published as an official AD&D 2nd Edition spell. D&D Portal therefore presents its 2e version as a homebrew Portal Conversion rather than as historical rules content. AD&D 2e did publish other acid spells, such as Melf's Acid Arrow and higher-level acid effects, but those are separate spells and should not be treated as official versions of Acid Splash.
Acid Splash is familiar from later editions, which can make it seem as though every older edition must also have contained a version of the spell. That is not the case for AD&D 2nd Edition. The D&D Portal entry fills that gap deliberately. It asks how the later Acid Splash concept could function as a native 2e Wizard spell while clearly separating that homebrew conversion from the edition's actual published spell catalogue.
There is no official 2e Acid Splash spell

That absence is important because the conversion changes several mechanics to fit 2e. Those changes are design decisions rather than lost or reconstructed official statistics.
The edition selector and source field should both communicate the distinction. A reader should be able to tell immediately that 2e Acid D&D Portal - Acid Damage type Acid is a damage type used by attacks,

Why D&D Portal includes a conversion
D&D Portal tracks spell concepts across editions. When a spell exists officially, the site records the published version; when it does not, a clearly labelled conversion can provide an optional edition-native interpretation.
The 2e conversion is not a direct mechanical translation. It changes level, resolution, school terminology, and splash behavior so the result fits AD&D 2e play more naturally.
That approach follows the Portal principle that a conversion should answer how the spell might have been designed for that edition, not merely replace modern terminology with older labels.
How the Portal version should be identified
The 2e page should be displayed as “2e • D&D Portal Conversion” rather than simply “2e.” Its source should likewise be D&D Portal Conversion rather than an official TSR or Wizards D&D Portal - Wizard Character class An Intelligence-based prepared full caster with the largest spell-learning system, ritual flexibility, and subclass traditions focused on schools or specialist theories.

spells, class features, resistance, immunity, and vulnerability. Full link: https://dnd-portal.com/rules/damage-types/acid/ spells can still be cited as design references where useful, but they do not become the publication source of Acid D&D Portal - Acid Damage type Acid is a damage type used by attacks,

Keeping those labels explicit protects the historical accuracy of the wiki and lets players decide whether their campaign allows the homebrew option.
