This item is designed awesomely. There's only one real fault with it: cacophonic guard? Do you know when that would be useful? If the item didn't have a minimum level. If it was a no minimum level item, I could see me slot a bunch of whatevers at level 1 alongside master's gift and laugh my hat off. Or heavy fortification, fear immunity, vitality +20 at level 11. Or NEVER at level 24.
What's with developers and their need to make trinkets way over level?
This item falls for me in the Gem of many facets category. Oh hell yeah, I'm gonna wear this gem and get +2 attack bonus at level five if I wear a pair of +3 jump boots! So powah, much swag
