Description

Swarming locusts fill a 20-foot-radius Sphere centered on a point you choose within range. The Sphere remains for the duration, and its area is Lightly Obscured and Difficult Terrain. When the swarm appears, each creature in it makes a Constitution saving throw, taking 4d10 Piercing damage on a failed save or half as much damage on a successful one. A creature also makes this save when it enters the spell's area for the first time on a turn or ends its turn there. A creature makes this save only once per turn.

At Higher Levels: The damage increases by 1d10 for each spell slot level above 5.

Doungim Lore

School Fit

Conjuration is the school of making something appear where nothing was. Summoned creatures, conjured objects, opened portals — every spell in the school changes the contents of a space. The school tag on Insect Plague is obvious from the effect — the spell places matter or creatures into the world that were not there before the cast. The 5th-level slot is precious; Insect Plague earns its slot or doesn't.

Class Fit

  • Cleric: Clerics often prep Insect Plague for a single arc — a kidnapping arc, a planar arc, a politics arc — and swap it out when the arc ends. Concentration is the binding cost — Insect Plague can't share a slot with another concentration spell.
  • Druid: Druid concentration is precious. Most Druids prep one big concentration spell and one non-concentration utility per day; Insect Plague fits one of those slots. As a concentration spell, Insect Plague occupies the caster's single concentration slot.
  • Sorcerer: Twin Spell turns single-target spells into two-target spells; if Insect Plague is single-target, Twin doubles its value. Insect Plague has an at-higher-levels rule; the spell's per-slot scaling makes upcasting worthwhile in the right context.
