Most of the lucky hits seem a bit “meh”. Keep in mind that lucky hit is a double roll, so you first have to roll a lucky hit and then you roll for your “up to a 5% chance” proc.
Small chance to heal isn’t great. Small chance to restore resource is okay. Small chance to immobilise, I don’t really care. Small chance to daze is okay as it’s effectively a stun.
Random 1% to 270% of your normal damage. You’ll average out to around 135% damage, so it could just be replaced by an item giving +35% damage.
It’s a fun item, I guess, but I’d really hate to have a string of 5% damage hits against a boss.
