Guild Wars 2

NEW: Sigil of Ruthlessness: Gain 5 might (3 seconds) when interrupting a foe.
NEW: Sigil of Absorption: Steal a boon when interruption a foe.

gg. Staff removed for thief.

I don’t really think that this is going to make anyhow great difference.

3 seconds of might is crap, unless it’s 25 stacks, which it won’t be. It needs to be 6 seconds IMO. The boon on interrupt looks nice though. I’d totally run that on a D/P thief. The other options, don’t know which will be best. Strength is nice but requires 10 seconds for 5 might stacks, purity can help with conditions, nullification can make you an even more powerful boon stripping/stealing machine, and some of those passives look nice. I’d probably end up going all out boon stripping.

Force and Draining are superior to both of these. Similar with Condi builds. Ruthlessness won’t beat Force until at least two Ints land in 3s and then it is only good for those 3s. Force is always on and basically akin to running at least 5 stacks of might all the time.

Absorption would be great if it went through Stab and Blocks but it doesn’t. The only time it is clearly worth having is against resistance builds when running condi. I carry an offhand pistol with the sigil for just such occasions but otherwise the more general sigils are better.
