This can be easily done very early on in the game, if you are the type of person who likes to get Trophies ASAP, here is how you can;
Once you acquire the
Bow of Apollo, it costs 2500 Red Orbs to upgrade it - at this point you should have well over this amount (I had just under 4000).
Go into the Menus, select the Bow and
hold to transfer the Orbs into the weapon - Trophy will unlock one all 2500 have been transferred.
