The spell Silence as described in the PHB:
For the Duration, no sound can be created within or pass through a 20-foot-radius Sphere centered on a point you choose within range. Any creature or object entirely inside the Sphere is immune to thunder damage, and creatures are Deafened while entirely inside it. Casting a Spell that includes a verbal component is impossible there.
The spell is obviously a useful tool against magic wielders, but I'm trying to get clarification on its limitations.
Would it be common for magic users to recognize the Silence spell and know easy ways to counter its effects? For example, a wizard familiar with the spell might know to just run a short distance in any direction to leave its area of effect, and then continue casting spells. I understand that different types of characters will have different knowledge of spells, but Silence isn't a high level spell and would seemingly be well known to many mid- and even low-level magic users.
The related question below might shed light on how a character would react to the Silence spell, because they might instead interpret the effect as being deafened.
