Something wrong with this week's Blue Mage advanced challenge - a bug?

[Eryna]

Now the problem is actually winning without any heals... I was able to complete Act 1, but I keep getting defeated by the add's poison in Act 2. Dodging the line AoE is already a pain. The adds just make it ultra difficult. When the adds appear, I silenced the Golem big spell. Then I tried to freeze the adds with Ram's Voice, and then Peculiar Light, and spam Plaincracker since they're weak with earth. But it didn't take them long to release themselves, and use like 5 poisons on me. Without my heals (3 star), I died almost instantly. Any tips?

I used Drain (Role Action) to heal myself.

That's really smart! I'll try that later! Still, I think my major problem wasn't something Drain alone can resolve. I probably need to deal with the adds with a better strategy.

When the adds appear just use Level 5 Petrify on them, apply Peculiar Light and burn them with Plaincracker.
