It's weird. I tried to imbue a Longsword [a practice weapon] and I put 25 ssi, 44 hit fireball, 44 hit fire area, and 23 mana leech. That is clearly 4 properties, they don't come with any DI on them. I went to add FC 1 and it said the item has too many properties, so I figured maybe it just put it over the cap of 450% intensity. But then I tried to put something on that had 1.0 weight, and it wouldn't let me. When I went to modify an intensity it showed that the weapon had 5/5 properties. I'll post some screenshots tonight or tomorrow, but curious to know if anyone has had these issues.
