Worshipper – “Ship” [Campaign 2, Mission 4]

Thanks everyone. I found the booster myself. The dragons also helped with experience. I easily reached level 30. But I was still one level short for "The Call." Even without that, surprisingly easily (Veteran difficulty), I beat Botanist in the port - it's almost a shame. I "tied up" the dragons and ents using Hypnosis (I recommend this) - after which the elf started to glitch, or maybe he really couldn't do anything. Still, the battle was a huge pleasure - all of Agrail's unique abilities and many Darkness spells were actually useful. So demons are quite fine even without Chaos magic.
P.S. But I still want the s/ability. Went to another thread - Agrail's Solution.

Oh, by the way, I saw a Lighthouse on this level. Will it happen to work in the next mission?
