Let’s create a little checklist on when you can and can’t benefit from casting
guidance.
- Foresight. Can the caster discern, in the game world, that their or their ally’s skills are about to be tested? (With at least 6 seconds to spare!).
- Task Duration. Is the target able to complete the task they are being guided in within 1 minute?
- Situation. Is it socially acceptable to cast a spell right now?
- Range. Can the caster touch the target?
- Concentration. Is the caster still able to concentrate on the spell for the duration of the guided task?
If the situation meets all those requirements, go ahead and let your player cast
guidance. If not, explain why it doesn’t work!
