To Understand Is to Forgive?

Drink a potion with a glare of Tep's spark.

I've finished. I bet you have never drunk such a muck! Sorry, it's absolutely necessary, if you want to overcome Tep.
This potion contains the very essence of the illusory world, a distilled glare of Tep's Spark. It will make you see what's inside your enemy, make you understand him. You know, Tep's like a god with his strongest armor and sharpest weapon, and the most powerful magic that one can imagine. Your only chance to win is to feel this from the source.

If I had a choice I wouldn't dip into that abyss. However, I had to, and I had a drink... and I'm still alive.

Hush, hush.. It's all over. I was afraid you would turn gray. What you've seen is the real Tep. That is your enemy. Now his most wicked witchcraft will be helpless against you, though some of them still pose danger.
