Trial

You don’t want to get corrupted and stay in the Umoir forests forever, right? Listen to me then.

The Leper doesn’t kill. It transforms, corrupts, modifies, turns inside out not only your body, but your very Spark. The further, the faster.

First of all, we have to understand how deep the Leper is in your body. The most accurate test is to see your abilities in combat.

How curious! I’ve never seen such a manifestation of the Leper!

Have you brought any alterations into your body before you met the Leper? Have you ever drunk Dragon’s blood, for instance? You have? I knew it!

I haven’t figured out how the Leper works yet, but I am positive that the source of it is the Astral - and who would resist the Astral best of all? Dragons! Their blood produces very strange effects, which you have just shown. Ah, anyway, the Leper is unlikely to make good to you. It might heal by itself or cause weird mutations, this is totally unpredictible. The impact of the Astral on the living matter hasn’t been studied enough, you know.
I’ll give you an artifact that is supposedly able to control the spread of the Leper across your body. It’s up to you to decide when to use it. And I’m not certain about the side effects, so make sure not to overuse it, or it might kill you on the spot, see?
