Best BG3 Spells for Beginners: Every Class's Must-Have Spells Ranked

Spellcaster’s Golden Rules for Beginners

1. Concentration matters. You can only concentrate on ONE spell at a time. Casting a second concentration spell drops the first. Pick one concentration spell at the start of each fight and build around it.

2. Saving throw spells vs attack roll spells. Spells that require an attack roll can miss. Spells that require a saving throw always deal half damage on a successful save (if the spell says so). Against high-AC enemies, use saving throw spells.

3. Upcasting. Many spells can be cast using higher-level spell slots for bonus effects. Healing Word at Level 3 heals more than Healing Word at Level 1. Fireball at Level 5 deals 10d6 instead of 8d6.

4. Never waste a spell slot on healing in combat unless reviving a downed ally. Healing 7 HP from Cure Wounds won’t save anyone. Killing the enemy faster will. Use Healing Word (Bonus Action, ranged) exclusively for picking up downed allies.

Spells to Avoid as a Beginner

Spell	Why Avoid
True Strike	Costs an action to give Advantage on next attack. Just attack twice instead.
Witch Bolt	Concentration for mediocre damage. Enemy walks out of range, spell ends.
Feign Death	Extremely niche. You’ll use it zero times.
Find Traps	Doesn’t actually find traps. Just reveals that traps exist (you already know).
Mordenkainen’s Sword	A level 7 spell that deals less damage than a level 2 Spiritual Weapon.
