How Eldritch Blast Works in D&D 5e
Eldritch Blast functions like a magical ranged attack, dealing force damage to targets. Unlike other cantrips, it scales by adding more beams instead of increasing damage:
- Level 1-4: Fires 1 beam (1d10 force damage per hit)
- Level 5-10: Fires 2 beams (each 1d10 damage)
- Level 11-16: Fires 3 beams (each 1d10 damage)
- Level 17+: Fires 4 beams (each 1d10 damage)
Each beam requires a separate attack roll, meaning you have a better chance to hit multiple targets.
