Speed Thunder (ブーストサンダー Būsuto sandā, lit. Booster Thunder in the Japanese version) is a Tome that is introduced in Fire Emblem Fates. A rare tome, Speed Thunder is comparable to Fimbulvetr, but lacks an Attack Speed penalty. Engulfing a selected enemy target in a cage of blue lightning, Speed Thunder boosts the Speed of nearby enemy units, and is risky to use in the presence of multiple enemy units.
