Frode is so concerned with the abilities of the special undead because of Tullas.
Although he always complained about Tullas causing destruction when they were in Originheart City, as they spent more time together, he gradually understood Tullas. He's just a slightly silly big boy, very pure-hearted. If Frode were still alive, he might mock him as an idiot, but since becoming a soul body, Frode has grown to like this kind of pure-hearted person more and more compared to unpredictable complex personalities.
Earlier, Angel mentioned there was a chance for Tullas to also learn soul tricks.
Since then, Frode has been attentive to it.
There are two mainstream methods for learning soul tricks. Adar and Shanni learn through death energy, which is relatively safe but tends to be mediocre.
The second method involves killing and absorbing special energy from the undead to assist in learning soul tricks.
