Acorn Protection Chant/Talisman
The acorn especially is well suited for magicks of protection. Obtain an acorn or two (pine cones can substitute in a pinch, be sure though to alter the spell accordingly) and say:
“Acorn true, acorn seed
Hush and listen to my need:
Protection from all harm I ask
Fail me not in this task.”
Bless Acorn and empower as per usual method; Carry acorn in pocket or purse.
