The Citadel of Chaos

A sudden intense flash of light bursts out in front of you.
You shield your eyes and then rub them —
but you cannot see! Panic hits you as you hear a low growling noise.
Padded footsteps come closer and you cry out in pain
as this unseen creature roars and embeds its sharp teeth in your leg.

Will you:

Cast a Strength Spell ?

Cast a Weakness Spell ?

Draw your sword and slash out at the creature ?
