Igneous Weapons Morph gives Spell DMG and WEAPON DMG to character and allies. At certain locations I noticed that only 1 buff was showing under the Title Igneous Weapons. The Major Brutality buff was missing. I checked my stats and indeed my Weapon DMG had not Increased, only my Spell DMG.
Should some1 like to confirm that IGNIOUS WEAPONS malfunctions at certain locations try these:
Skalar's Hoster(boss quests at Wrothgar)
Cyrodiil Keeps(as soon as u port via transitous Shrines give it a go, u will not gain Weapon DMG)
Imperial City Sewers alliance base at corridors and doors.
I also happen to notice it while I was gathering for a raid at Accursed Nursenry. Don't remember my exact location.
I have tested this problem with another person at Skalar's Hoster. While inside he admitted that he only got Igneous Weapon buff icon(which only increases Spell DMG) but not Major Brutality Icon, and that his weapon dmg did not increased. When we stepped outside I used Igneous Weapons again and we noticed 2 buff icons, Igneous Weapons and Major Brutality. Then we looked at our Weapon Damage and it was truly increased.
I have not tested Molten Armaments or the skill without Morphing it.
This is kinda serious for certain builds. Please have a look at it.
