Aghanim's Scepter

Rod, legendary (requires attunement by a Spellcaster)

A crystalline scepter humming with arcane intelligence. Runes shift and rewrite themselves as spells are cast, as if the magic itself is learning.

Spell Amplification

While attuned to Aghanim’s Scepter, when you cast a spell of 1st level or higher, you may choose one of the following Aghanim Enhancements to apply to that spell.

You can use this feature multiple times, depending on your level, after a long rest.

At level 3 =up to 3 slots
At level 6 = up to 6 slots
At level 9 = up to 9 slots

Only one enhancement may be applied per spell unless stated otherwise.

Aghanim Enhancements

1. Overcharged Power

Damage Amplification

The spell’s damage dice are doubled
(e.g., 8d6 → 16d6)
This does not double flat bonuses (like +CHA mod).

This does stack with effects that already double dice instead it adds plus the would be dice. (like crits). (e.g., 8d6 → 16d6(Aghanim's) + 8d6(crits))

2. Arcane Multicast

Target Expansion

If the spell targets one creature, it may instead target:
- Two additional creatures within range
Each target is affected independently.

At spell level 6 or higher, you may target three additional creatures instead.

3. Widened Spellfield

Area-of-Effect Expansion

If the spell creates an area (sphere, cone, cube, line, etc.), its radius or length is doubled
Shape remains the same

Example:
Fireball (20-ft radius) → 40-ft radius

4. Echo of Magic

Effect Repetition

The spell’s primary effect triggers twice
- Damage is rolled twice
- Conditions are reapplied (save separately if applicable)
If the spell requires concentration, the second effect happens immediately, not later.

The same creature cannot be affected twice by a condition if the condition wouldn’t normally stack (DM adjudication applies).

Arcane Strain

Each time you use an Aghanim Enhancement, you gain 1 Arcane Strain.

At 3 Arcane Strain, you take 2d6 force damage
At 5 Arcane Strain, you gain 1 level of exhaustion
At 6+ Arcane Strain, you gain +1 level of exhaustion per Arcane Strain above 5
All Arcane Strain resets on a long rest

Arcane Mastery

If the wielder can cast 9th-level spells:

Once per long rest, you may apply two different Aghanim Enhancements to the same spell
Doing so immediately gives 3 Arcane Strain

Lore

Aghanim’s Scepter was forged not to create new spells—but to perfect existing ones.
It rewrites the arcane formula mid-casting, forcing magic beyond its intended limits.
