The demonic, psychic and cybernetic distribution in Kaidan

This is actually confusing but I did a little googling and found this dev blog from the lead designer. I have added emphasis to the key parts of the paragraph.

In order to explain the progression we need to start talking about xp. At the bottom of the screen is the xp bar, and when the player has filled up 1/3 of it they will be given an ability point. Filling out the whole bar gives a skill point. A player gets xp from many different sources: Killing monsters, PvP, missions and crafting. The amount of xp needed to get an ability point or a skill point is static.

So it looks like everyone was on the right-ish track but I think we were reading too much into the bar.

EDIT: A bit more info from playing more tonight. The blue area will fill up each third of the XP bar as your progress. When you completely fill the bar you will get an AP point and the redish tint will go over that section of the bar. When you fill all three bars, that is when you get an SP.

There is a location a lot closer where you can find the slow and dry moving zombies. And that is if you go from Norma's house, to the street and turn right following the street till you reach a fence. Reaching the beach and close to pyramid point. Past the fence are cultists, and walking around in that area are called (reawakened, or something else will check later on) warrior. Also there are Slow and Dry zombies at the Graveyard, behind the church (Dearly Departed.) These count as Dry and slow zombies.

In that location you can get both the cultists and slow and dry.

I'll post a screenshot later on.
