Acid Splash 4e FAQ FAQ
Did Acid Splash exist as a spell in D&D 4e?
No. Acid Splash was not published as a spell or attack power in D&D 4e. An official 4e feat named Acid Splash does exist in Dragon #380, but that feat is a separate game element rather than a version of the earlier spell. The closest official low-level Sorcerer comparison is Acid Orb, a level 1 at-will spell from Player’s Handbook 2. The Acid Splash entry on D&D Portal is therefore a clearly labeled Portal Conversion rather than an official 4e spell.
The name Acid Splash does appear in official D&D 4e material, which makes the history less straightforward than simply saying that the name disappeared. The important distinction is what kind of game element used the name. In 4e, Acid Splash was published as a feat, not as a Wizard or Sorcerer attack power that continued the 3e and 3.5e spell. D&D Portal separates those two facts so that a reader can follow the spell concept across editions without being told that a homebrew adaptation was historically published. The 4e spell page is therefore intentionally presented as a Portal Conversion designed to behave like native 4e material.
Acid Splash was not an official 4e spell

spells, class features, resistance, immunity, and vulnerability. Full link: https://dnd-portal.com/rules/damage-types/acid/ Splash that continues the earlier spell’s rules.
That distinction matters more in 4e than it might in another edition because offensive spells are normally expressed as class powers. A genuine 4e continuation would be expected to have a class, power level, usage frequency, action type, range, target, attack defense, keywords, and a hit or effect entry.
Because no such official Acid D&D Portal - Acid Damage type Acid is a damage type used by attacks,
spells, class features, resistance, immunity, and vulnerability. Full link: https://dnd-portal.com/rules/damage-types/acid/ Splash power exists, D&D Portal does not present the 4e page as a recovered or reconstructed official rule. The edition entry is explicitly marked as a Portal Conversion so the historical record and the playable conversion remain separate.
An official feat uses the name Acid Splash
Official 4e material did reuse the name Acid D&D Portal - Acid Damage type Acid is a damage type used by attacks,
spells, class features, resistance, immunity, and vulnerability. Full link: https://dnd-portal.com/rules/damage-types/acid/ Splash for a Paragon-tier Wizard 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.

The feat does not recreate the 3e or 3.5e spell. It does not function as a reusable Acid D&D Portal - Acid Damage type Acid is a damage type used by attacks,
spells, class features, resistance, immunity, and vulnerability. Full link: https://dnd-portal.com/rules/damage-types/acid/ projectile and should not be treated as the 4e edition of the spell merely because it shares the same name.
This naming overlap is one reason searches for “ Acid D&D Portal - Acid Damage type Acid is a damage type used by attacks,
spells, class features, resistance, immunity, and vulnerability. Full link: https://dnd-portal.com/rules/damage-types/acid/ Splash 4e” can produce confusing answers. A result showing the official feat proves that the name existed in 4e, but it does not prove that an official spell or attack power D&D Portal - Attack Roll Combat rule Attack Roll is a combat rule used by attacks,
damage, defenses, or turn order. Full link: https://dnd-portal.com/rules/combat/attack-roll/ with that name existed.

spells, class features, resistance, immunity, and vulnerability. Full link: https://dnd-portal.com/rules/damage-types/acid/ projectile can look like.
Acid D&D Portal - Acid Damage type Acid is a damage type used by attacks,

spells, class features, resistance, immunity, and vulnerability. Full link: https://dnd-portal.com/rules/damage-types/acid/ Splash. It has Ranged 20, stronger single-target damage, and specific permission to function as a ranged basic attack. D&D Portal therefore uses it as a design reference instead of treating the two names as interchangeable.
Why D&D Portal created a 4e conversion
D&D Portal is intended to let readers move through the history of a spell across editions. When an edition contains an official version, the site can document that published version. When the spell is absent, a conversion can fill the playable gap without rewriting history.
The 4e conversion therefore asks how the earlier Acid D&D Portal - Acid Damage type Acid is a damage type used by attacks,
spells, class features, resistance, immunity, and vulnerability. Full link: https://dnd-portal.com/rules/damage-types/acid/ Splash concept could be expressed through native 4e mechanics. That means using an At-Will attack power D&D Portal - Attack Roll Combat rule Attack Roll is a combat rule used by attacks,
damage, defenses, or turn order. Full link: https://dnd-portal.com/rules/combat/attack-roll/, an implement, an attack against a defense, class-appropriate ability scores, and level-based damage scaling rather than importing the older 3.x spell framework unchanged.
The result is original D&D Portal homebrew informed by 4e design conventions. It should be judged and used as a conversion for 4e play, not cited as evidence that 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. Full link: https://dnd-portal.com/classes/wizard/ published an Acid D&D Portal - Acid Damage type Acid is a damage type used by attacks,
spells, class features, resistance, immunity, and vulnerability. Full link: https://dnd-portal.com/rules/damage-types/acid/ Splash spell for the edition.
How to tell official and converted content apart
The 4e edition entry should visibly include the Portal Conversion label. That label is part of the content status, not a minor footnote, because it tells the reader that the mechanics on the page were created by D&D Portal.
Official references should remain separate. The Acid D&D Portal - Acid Damage type Acid is a damage type used by attacks,
spells, class features, resistance, immunity, and vulnerability. Full link: https://dnd-portal.com/rules/damage-types/acid/ Splash feat from Dragon #380 and Acid D&D Portal - Acid Damage type Acid is a damage type used by attacks,
spells, class features, resistance, immunity, and vulnerability. Full link: https://dnd-portal.com/rules/damage-types/acid/ Orb from Player’s Handbook 2 can be discussed as published 4e material, while the converted Acid D&D Portal - Acid Damage type Acid is a damage type used by attacks,
spells, class features, resistance, immunity, and vulnerability. Full link: https://dnd-portal.com/rules/damage-types/acid/ Splash power should be discussed as a compatibility-oriented homebrew option.
This separation also prevents edition history from becoming ambiguous later. A future reader, search engine, or rules discussion should be able to distinguish “official 4e content called Acid D&D Portal - Acid Damage type Acid is a damage type used by attacks,
spells, class features, resistance, immunity, and vulnerability. Full link: https://dnd-portal.com/rules/damage-types/acid/ Splash” from “an official 4e Acid D&D Portal - Acid Damage type Acid is a damage type used by attacks,
spells, class features, resistance, immunity, and vulnerability. Full link: https://dnd-portal.com/rules/damage-types/acid/ Splash spell,” because only the first statement is supported.
