Skill Sets A1-A4

[Nevarie]

I'm confused.. where exactly are these ussed? I looked through the ENTD tab battles and couldent find them being used anywhere. Am I blind or did they really leave 4 unused skill sets in there?

I believe those are the undead units' skill sets, IIRC theyre missing a few of the skills from the normal version of the skill sets.
