In the attached screenshot, you can see that Devour 9 isn't displaying correctly. It might be an Apotheosis Ascended issue since the roman numeral for the effect displays properly when using /effect, but I am going to report it here too just in case.

This is a Minecraft issue (same thing happens with enchantments) and I personally don't have interest in fixing it.

I'll probably nerf the values given from Ascended to avoid this kind of issue, they were intended to be temporary values anyway, but no-one complained about the balance of them or anything.
