I have identified all of the new traits associated with the newest Alchemy Reagents and will now list them. As a bonus I will also list the old traits that can be found on them too.
Beetle Scuttle: Lower Spell Resist / Increase Armor / Protection / Vitality
Butterfly Wing: Restore Health / Lower Spell Crit / Sustained Restore Health / Vitality
Fleshfly Larva: Ravage Stamina / Vulnerability / Creeping Ravage Health / Vitality
Mudcrab Chitin: Increase Spell Resist / Increase Armor / Protection / Defile
Nightshade: Ravage Health / Protection / Creeping Ravage Health / Defile
Scrib Jelly: Ravage Magicka / Speed / Vulnerability / Sustained Restore Health
Spider Egg: Reduce Speed / Invisible / Sustained Restore Health / Defile
Torchbug Thorax: Lower Armor / Lower Weapon Crit / Detection / Vitality
I'll let ya'll experiment to see what the traits do
Pretty self-explanatory though based on the trait name. They're all Minor buffs/debuffs though. Here's a quick list of the new ones for quick reference:
Positive
Sustained Restore Health
Protection
Vitality
Negative
Creeping Ravage Health
Vulnerability
Defile
Hope this helps
