Similar to yourself, ignore, block, "shield wall", passive reflection, be wrapped in thorns.

That last one relates to Thurisaz and opposing brute force (as giants use). It's passive/reactive but directed to the target/intrusive brute energy.
Allow them to bash, pricking themselves over and over eventually burning out.
Why expend energy when you can let them take care of themselves? Below is a rune/spell song/poem that I have paired with visualizations. There are strong associations with Thor/Mjolnir, hence the hammer reference. Also worth noting is that nightingales nest in blackthorn in order to protect themselves from predators. There's a whole Fae rabbit hole to go down with that as well.



Thrice they wrap around,
The thorns to protect.
Grown strong from the ground,
The thorns will deflect.

This guard makes no sound,
Deep wounds t'will inflict,
The hammer will pound,
And skin will be pricked,

Dark purpose now found,
Pinched off as a wick,
Flee! Lest ye spellbound;
And mind become bricked.



I think I've given you enough detail to find/conjure some appropriate imagery if you'd like add this your repertoire, but here's a rune card for Thurisaz to help further.
