Guild Wars 2

Masshypnosis.9367:

Mhm… Sigil of Battle = 3 Stacks of Might on weapon switch and sigil of fire = chance of flame blast on crit. That work.

The other guy stated it correctly, all Sigils share the same internal cooldown. So if you get a fire blast and switch elements within 5 seconds, you won’t get 3 stacks of might, and if you switch elements and get 3 stacks of might, your crits won’t make fire blasts for 9 seconds. You do get the effects of both, but because they share cooldowns, it really isn’t optimal at all.

It took me like a month of playing D/D to finally question why it didn’t seem like superior sigil of battle was doing as much as I think it should, and I stumbled upon that shared internal cooldown blurb on the wiki in the Sigils article.

Would I be correct in assuming that in the best case scenario (100% crit rate, Arcane skill every 10 seconds, no other +% critical damage), this Master Major trait gives a whopping 2% increase in damage (153/150)?

More likely you have a 50% crit rate and can only Arcane half the time for an amazing increase of 0.6% effective damage if you run no other +% crit damage.

Makes even the fairly lackluster Bolt to the Heart look pretty good with its <5% increased effective damage (which at least has a reason to exist in “spike him to death NOW” situations).
