Stuck on Phil Cup Round 5

[Destinywind]

I'm in round 5 of the Phil Cup and fighting a Cannon Gun and a Warlock Step. When the Warlock Step attacks, it reduces my strength x5. This makes all my hits do only 1 damage. I used Esuna, but it doesn't seem to remove the effect. What am I supposed to do?

It mostly depends on your medals.

Anyway, Esuna I won't help you, it just removes status ailments like 'poison', 'paralysis' and 'sleep'; I'm finding that "KH CoM Naminé ", which copies target's enhancements, is really useful in order to get rid of these malus or steal some bonus!
