This is a page from my book of shadows:
To Call Luck
Burn few Rose Petals at thine Altar, and then say the following Enchantment.
I need some Luck, so bring it here,
the Bad Luck shall now disappear.
So please receive my Desperate Call,
and bless with Luck my Luckless Soul.
And when the Hour Twelfth shall strike,
my Luck shall be as it was like.
