Wild Arms 2 [Demo Disc] [Playstation Underground]

On the extremely thin spine, there is a Quest and Riddle:
Find five HIDDEN Letters to Spell a Secret Word. Hint: Oliver (the enemy boss in Lilka’s opening quest) is weak against her ________ attack.
This is from the PlayStation Underground and shipped to subscribers. It’s a tri-fold cardboard sleeve with a nifty gimmick to it.

The gimmick comes in the packaging’s use of clear gloss patterns. If you look at the featured sections below in direct lamp light and tilt the case, you’ll see the glossy messages reflected. The 5 sentences read:

F – The Future of Filgaia
l – Only on PlayStation
a – Ricochet the “Hurl Knife” to activate hard to reach switches
m – Equip guardians immediately. Ultimate Control
e – Condition Green nullifies abnormal status.

Since I already ordered them for you, it spells out the answer that “Flame” is Oliver’s weakness.
