What happens when you use Extended Spell on Shield? The duration increases to two rounds (12 second total). So round two, you still have the +5 AC. You’re now hit again, and you have your reaction back (new round) so you Shield again.
Can you be affected by the same spell twice 5e?

What is meta magic?
Metamagic was a group of skills used by spellcasters, including wizards, sorcerers, illusionists and other casters focusing exclusively on arcane magic for their survival and livelihood.

Can a metamagic be used more than once?
No, you can only use a metamagic option once per spell. This question is explicitly addressed in the Sage Advice Compendium: Metamagic rules state you can’t use multiple Metamagic options on a single spell. Can you use one option multiple times?

Can a sorcerer quadruple the duration of a spell?
For instance, a sorcerer can’t quadruple the duration of a spell by spending 2 sorcery points on Extended Spell. This fits with the explicitly stated restriction that you can only use one Metamagic option on a spell when you cast it; likewise, you can only use that option once on a spell you cast (it doesn’t stack with itself).
