Illusion Magic

Interesting. It probably won't dispel the rumor about the Death Plain but it might work well on Dag.
According to this Stone Tablet, the Death Plain is under a phantom spell. The spell was for protecting a temple which once stood there, so that a phantom appeared to anyone approaching the temple. I think Dag saw one of them.
The Stone Tablet has instructions on how to break the spell, so I think different people made the spell and the Stone Tablet. I need some ingredients to follow this, though. Do this for me. I need <HFFFA7272>1 Piece of Rare Leather<HFFFFFFFF>. You can get it by using <HFFFA7272>Collecting Skill of Уровень 3 or higher<HFFFFFFFF> on <HFFFA7272>Duriven Поискers<HFFFFFFFF> in <HFFFA7272>The Span<HFFFFFFFF>.

I'll ask you again. I need <HFFFA7272>1 Piece of Rare Leather<HFFFFFFFF>. You will get it most easily by using <HFFFA7272>Collecting Skill of Уровень 3 or higher<HFFFFFFFF> on <HFFFA7272>Duriven Поискers in The Span<HFFFFFFFF>.

We're all ready. Let's try to get rid of Dag's fear.
