Mishap Table

When a Spellcraft research attempt misses by 10+, roll on this table immediately. The components for the attempt are consumed regardless, and the spell is not produced. A result of 19-20 inflicts a permanent magical curse from the Curses table.

Table

Roll — Backfires when a Spellcraft research attempt misses by 10+.

RollResult
1–3The caster takes 4d10 force damage and is knocked unconscious.
4–6A permanent visible scar appears at the spell's source point (hand, eye, throat).
7–9The caster loses access to one currently-known spell of the target spell's level for 1d4 weeks.
10–12A creature, object, or feature within 30 ft is permanently transformed in a small way (hair to snakes, table to stone, doorknob to mouth, etc.).
13–15The failure clouds the caster's thinking. They have disadvantage on all Intelligence (Arcana) checks for 1d4 weeks and cannot start a new spellcraft attempt during that window.
16–17The caster loses 1 Intelligence permanently. Restorable only via a 7th-level spell or a major plot beat.
18A hostile magical creature manifests, drawn by the disruption. CR equals the target spell's level.
19–20The caster acquires a permanent magical curse. Roll on the Curses table, or pick. Curses last until removed by remove curse, greater restoration, or a major plot beat.
