"Hold on," you tell him as you two approach a flight of stairs to a lower part of the ruin. "There's a magic barrier through here."
He stares. "I ran through it just fine."
"That was before I got here, and before I filled your body full of magic," you explain. "That barrier's going to trigger a trap once we go through. It'll probably activate more guards."
"Is there any way around?"
You shrug. "I'm saying this just so you're ready for what happens next. But, I might be able to dispel it if we take the time."
He nods and looks around. "You're the wizard, but I say we're not in a good position here to fight. The stairs and the hallway are going to close us in. We'll be trapped in a fight with nowhere to go."
