      How to read this list
      • Names are the cartridge’s own. The Spanish ones are often abbreviated (none is longer than 12 characters) and are kept as they are; each card also shows the name in the other language, and search finds both.
      • A spell's element is its last rune's: 294 of the 396 mix runes of different elements.
      • Effect: what the spell does, worked out from its data, with the same tags as the families. A spell can have several; the filter keeps the spells that have the chosen one. Spell families
      • Total effect: what one unit receives over the whole spell. The real figure depends on who casts and who receives it, so it is worked out for a fixed reference: the caster has magic 30 (Isaac at level 1), the element at level 1–10 and a perfect stroke (quality 1); the receiver has defense and magic defense 0, a neutral element and no weakness or shield; no random factor. “up to” is a maximum that needs every hit to land, or the unit to stay where the spell reaches it; “not confirmed” marks what the code read so far does not settle.
      • The badges come from the best spells guide; each one links to its explanation. Best spells
