Blade Ward

If a target creature would take damage this turn,
it instead only takes half of that damage.
"Quite simply, you can wiggle your fingers and
whisper some curse words. And as easy as that, now
you have resistance to most weapons... for about six
seconds. This spell is available to bards, sorcerers, warlocks, wizards, and (by extension) arcane
trickster rogues and eldritch knight fighters." - Doug
