considering both of the following...sure if something triggered the spell (you're reacting to something)...you can't just proactively cast shield because you know the bad guy is going to attack you when its his turn.
Reactions
Certain special abilities, spells, and situations allow you to take a special action called a reaction. A reaction is an instant response to a trigger of some kind, which can occur on your turn or on someone else's. The opportunity attack, described later in this chapter, is the most common type of reaction.
When you take a reaction, you can't take another one until the start of your next turn. If the reaction interrupts another creature's turn, that creature can continue its turn right after the reaction.
Shield
An invisible barrier of magical force appears and protects you. Until the start of your next turn, you have a +5 bonus to AC, including against the triggering attack, and you take no damage from magic missile.
So shield is a spell that has a casting time of a reaction, does that mean you can cast it after you cast your spell that requires an action?
