Bugs

• Despite not dealing any ⁠Poison damage, this spell is tagged as a poison DamageType.
• When first cast on an enemy, the combat log displays the enemy as making two separate saving throw rolls.
• After the initial cast, subsequent turns of Insect Plague use the Constitution modifier of the caster, not the spellcasting modifier, in order to determine Difficulty Class.
• When upcast to  Level 6 Spell Slot, Insect Plague is missing a technical condition which is normally applied when a creature first enters the radius. This causes the following behavior, which is different from when cast at  Level 5 Spell Slot:
  • Damage is dealt both when a creature first enters the radius and when it ends it turn within the radius on the same turn.
  • Damage is dealt each time a creature exits and re-enters the radius during a turn.
