What is Spell Slot Calculator 5e?

In Dungeons & Dragons 5th Edition, a “spell slot” is effectively a resource spent to cast a spell. While single-class characters follow their class table, multiclass characters require a specific spell slot calculator 5e to determine their combined power.

This calculation relies on the “Spellcasting” feature. Classes like Warlocks are excluded because they use “Pact Magic,” which operates on a separate progression and is tracked independently from standard spellcasting slots.

How to Calculate Spell Slot Calculator 5e (Example)

  1. Determine your levels in each class category.
  2. Example: A Level 3 Wizard (Full), Level 2 Paladin (Half), and Level 1 Artificer.
  3. Calculate Wizard: 3 Levels.
  4. Calculate Paladin: floor(2 / 2) = 1 Level.
  5. Calculate Artificer: ceil(1 / 2) = 1 Level.
  6. Total Effective Level = 3 + 1 + 1 = 5. Look up level 5 on the multiclassing table.

Frequently Asked Questions (FAQ)

How do Warlocks affect my spell slots? Warlock levels do not add to your effective spellcasting level. Pact Magic slots are tracked and recharged separately.

Do I round up or down for Artificers? Per Tasha’s Cauldron of Everything, Artificers round UP when multiclassing, unlike Paladins or Rangers.

What is the maximum effective level? The effective level for spell slots caps at 20, even if your total character level exceeds this (which isn’t standard RAW but occurs in homebrew).

Can I use slots to cast spells from any of my classes? Yes! You can use your 5e spell slots to cast any spell you know from any class, provided the slot is of high enough level.
