Each Daevanion crystal adds 1 item level, Azphel ones included

What people say

Korean and German guides say Daevanion raises item level “one by one”. None of them clarifies whether a stat node counts the same as a skill node, or what happens with Azphel, the PvP board, which has its own crystal counter.

What happens

I measured it spending only crystals, without touching anything else in between:

Crystals	Before	After
12, in Zikel and Nezekan	941	953
7, in Zikel and Nezekan	1,285	1,292
2 Azphel	1,376	1,378

Always one point per crystal, whatever the node. Azphel ones count too, even though their nodes are health, mana or PvP.

What to do

• Don’t leave any crystal unspent: each one is item level.
• The Nightmare shop sells regular crystals at 300 fragments, 50 per character. Every good Nightmare run gives enough for several.
• The Abyss shop sells Azphel crystals at 10,000 Abyss Points, 20 per character. They also work for raising item level, even if they add little to combat power.
