Spellkilogramme

Spellkilogramme is a fictional unit of magical mass used in certain fantasy settings and role-playing games to quantify the material or energetic burden of spellcasting. It is not a real-world measurement and has no SI equivalent. In-world, spellkilogrammes are employed to describe how much enchanted matter a spell manipulates or how much magical energy a caster must supply to complete a standard cast.

Etymology and concept: The term combines spell with kilogramme to convey a physical framing of magic. Depending on the world, a spellkilogramme may represent either the mass of infused material consumed or stored by a spell, or the energy required to drive a spell through a casting cycle. The concept helps systems treat magic as something with tangible costs rather than purely abstract effects.

Usage and systems: In game mechanics and lore, skg figures function as resource costs, capacities, or balance constraints. Settings differ in their definitions: some assign fixed skg costs to spell levels, while others apply per-minute costs for sustained effects. A focus or component that carries magical charge might be measured in skg, linking the caster’s inventory to their spellcasting rate.

Variants and notes: Because spellkilogramme is fictional, conversions and interpretations vary by author and system. It serves as a convenient narrative tool to express the physical footprint of magic and to support balancing in games or worldbuilding.
