Is there something wrong with this week's Blue Mage challenge?

In the Advanced Challenge this week, there's "Enfeeble Me Tenderer" (apply 10 or more unique enfeeblement) and "Beginner Spellcasting" (use only rank 1 and 2 spells). As far as I know, "enfeeblement" include the following:
Slow (Ice Spike)
Deep Freeze (Ram's Voice)
Paralyze (Mind Blast, Glower or Dragon's Voice)
Stun (Faze, Bomb Toss or Sticky Tongue)
Dropsy (Aqua Breath)
Blind (Ink Jet)
Silence (Flying Sardine)
Silence/Paralyze/Malodorus/Slow/Blind/Poison/Heavy (Bad Breath)

Bad Breath is 3 star, Aqua Breath is 4 star, and Ink Jet is 3 star.

So the remaining 1 and 2 star skills will only give:
Slow
Deep Freeze
Paralyze
Stun
Silence

I guess Peculiar Light can be considered an enfeeblement too?

How about Level 5 Petrify? Would that work?

Even including Petrify and Peculiar Light, that's only totaled up to 7 though! How the heck do you get 10 enfeeblement?
