Guild Wars 2

Mug: How much damage?
Improvisation: Can it roll an Utility Skill type you do not currently have equipped, therefore wasting said roll?

Shadow Protector: Also affects self, but this is unspecified.
Shadow’s Embrace: Also removes a condition instantly, but this is unspecified.
Cloaked in Shadow: How long does the Blind last for?
Infusion of Shadow: You can benefit from this multiple times when using or gaining any effect that provide you with Stealth despite already being stealthed; the tooltip is unclear and appears to actually require stealthing.
Leeching Venoms: How much health is leeched?
Patience: How much Initiative?
Shadow’s Rejuvenation: How much healing?

Power of Inertia: How long does the Might last for? How many stacks of it?
Vigorous Recovery: How long does the Vigor last for?
Assassin’s Retreat: How long does the Swiftness last for?
Feline Grace: How much Endurance is returned?
Assassin’s Reward: How much healing?

Instinctual Response: How long does the Blind last? How about the Stealth?
Uncatchable: How long do the Caltrops last? What do they do?
Long Reach: How much is the range increase?

Cloaked in Shadow – Last I used it, it was around 3 seconds. This was quite some time ago though.

Infusion of Shadow – Stealth is a buff that stacks in duration. All other traits that affects things that stack in duration works when you add to its duration.

Patience – 1 per second.

Shadows rejuvenation – Around 70% of shadow refuge. I distinctly remember Shadow refuge healing me for 350+ and getting 200+ healing from the stealth.

Power of Inertia – 10 seconds

Feline Grace : about 40% of endurance used.

Uncatchable : 4 seconds, does the same as the caltrops utility skill

Long Reach : I remember it saying increases to 1200 range on the trait but I havent checked on it for so long…

Leeching Venoms…I remember someone posting the maths on that in these forums.

Have you tried testing these out in PvP(Heart of the Mists)? Numbers will vary between builds, so your best bet is to try it out yourself on target dummies/sparring bots. HotM allows for free respecs and grants level 80 while youre in there: a perfect staging area!

I’ve done it for some, but for, say, Mug or Leeching, it gets hard to calculate the exact formulas. For basically anything with numbers, actually. I figured someone would know here!

@ Oxygen: the SC for Mug must be between 1.4838 and 1.46, I need some more tests to get a more precise number, as soon as I’ll get it I’ll post it in my thread about weapons SCs.
