Fast Friends is a 5th edition Dungeons & Dragons (D&D) spell that allows the caster to charm a creature, making it friendly and willing to obey simple commands. The spell can be cast on creatures that can understand the caster, and it lasts for 1 hour or until the creature takes damage.
When the spell is cast, the creature must make a Wisdom saving throw. On a failed save, the creature is charmed by the caster and considers the caster its friend. The creature will obey simple commands and will not attack the caster or its allies.
Fast Friends can be a useful spell for convincing an enemy to stand down in combat, or for recruiting an ally from among a group of hostile creatures. The spell can also be used for non-violent purposes, such as convincing a guard to let the party into a restricted area, or convincing a shopkeeper to give the party a discount.
However, the spell should be used with caution, as the creature is not under the caster's complete control and may still act in its own self-interest. Additionally, the spell's duration is relatively short, so the creature may return to its hostile state after the spell has ended.
In summary, Fast Friends is a spell that allows the caster to charm a creature, making it friendly and willing to obey simple commands. It can be a useful spell for convincing enemies to stand down in combat, recruiting allies, or for non-violent purposes, but it should be used with caution as the spell's duration is short and the creature may return to its hostile state after the spell has ended.
