The massive amount of options that the Suggestion spell can provide, even whenever you factor out the unreasonable requests, can sometimes seem very overwhelming. If you don’t want to spend several minutes during a combat or social encounter thinking of a Suggestion that you can use, there are a few questions you can reasonably ask yourself to consider what you should suggest. First, think about what this creature would reasonably do. A dumb bugbear might be susceptible to more Suggestions than a trained guard. You might be able to convince the bugbear to fall on its face during combat, but you won’t have the same thing happen to a guard whenever you say the same thing to them. Most guards have some form of combat training, and they know that being prone in combat isn’t helpful. Thinking about the person or creature you are trying to suggest something to can help you roleplay and consider ways to make their Suggestion seem reasonable. Plus, it can be like a puzzle you need to figure out, and that can be fun. It also makes every interaction where you cast Suggestion different!
