Digging up this tweet concerning dispel magic. Looking for intent. Is the intent that you cannot target the "magical effect" of Water Walk to remove on every PC because in this scenario it's actually multiple magical effects, 1 effect per PC so the PC must be the target?

When you use dispel magic to target a magical effect within range, you're choosing a discrete effect that you're aware of, often one created by a spell. If a spell has put an ongoing effect on multiple creatures, each of those creatures bears a discrete, targetable effect. #DnD https://t.co/9rKRqFiezb

An implication of this may be that being effected by a spell may be discerned by viewing the target? https://t.co/R8iY8GZe2A

You know that a creature/object/space is affected by a spell only if the spell's effects are visible, you witnessed the spell being cast on the target, or you've otherwise detected/discerned the presence of the spell's effects. #DnD https://t.co/Diw1dRekvk

I'm curious about the words "that you're aware of." Does this mean that one could not cast "dispel magic" on a tomb, door, or creature unless you know what is affecting them? That is, can one cast dispel magic -for example- on a chest just in case there is a magical trap?

The text of dispel magic says you can target one of the following:
creature
object
magical effectThe spell doesn't require you to know what magical effect, if any, is on a creature or an object that you target. #DnD https://t.co/FAGYuxXutc
