Weakens· 15 of 18Slows or roots· 3 of 18How is the total effect worked out?
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.
To cast a spell you draw its runes, each in one stroke and each scored on its own: a long stroke with many turns takes longer and gives more chances to slip out of the shape. Each spell shows its runes, drawn from their strokes, with their level (I to III) and how long their strokes are added up, in widths of the rune: the game scales the drawing, so its size on screen does not count. A higher level is usually longer, but not always (Water II is shorter than Wind I).
