What is twinned spell 5e?

Twinned Spell is a metamagic option in 5th edition Dungeons and Dragons that allows a sorcerer to cast a spell that targets a single creature or object, and target a second creature or object with the same spell without spending an additional spell slot. The second target must be a valid target for the spell and within range of the sorcerer's spellcasting ability.

However, there are some limitations to Twinned Spell. The spell being twinned must be of a level that the sorcerer can cast, and cannot be a cantrip. Additionally, if the spell has a range of self, it cannot be twinned unless it specifically targets one creature in addition to the caster. Finally, a sorcerer cannot twin a spell if they have already used another metamagic option on it.

Some popular spells for twinning include spells that inflict damage, such as Scorching Ray, and spells that impose conditions, such as Hold Person. Twinned Spell is a popular choice for sorcerers who want to maximize their spellcasting abilities in combat and support their allies with their magic.
