Guild Wars 2

Just wondering if anyone has done the math or has a link to a similar thread as I haven’t been able to find any that weren’t just comparing Vampiric to Vampiric Precision (like my other post). One of the builds I run in PvP has 20 into Blood Magic and the Master trait is already Ritual Mastery and I can’t determine if siphon on crit from Vampiric Precision for double siphons via Vampric is better than an overall 50% increase to siphon abilities from Bloodthirst. I feel like Bloodthirst is better by default because it affects Vampiric, Life Siphon and Life Transfer, but I don’t know if the double heal on crit makes up for it (assuming 47%-58% crit as I float around there with Sigil of Minor Accuracy). Thoughts?

Hmm… Assuming everything’s at level 80…

To start, bloodthirst (BT) adds 12 healing to every vampiric hit, while vampiric precision (VP) is 32 to every crit. With a 50% crit rate, that’s about equivalent to 16 per hit. (I know you don’t want the thread to be about vampiric, but it’s there in your build so I’m going to take it into account.)

So without counting Life Siphon / Life Leech, VP is an improvement by 4 health per hit at 80.

The problem is, one use of life siphon with BT blows this advantage out of the water. At 80, you get a base of 200 health per pulse: BT improves that by 100. That’s the equivalent of 24 attacks with VP (25, but the pulse is an attack) and that’s per pulse. Even if you get interrupted halfway through and only land 4 pulses, that’s the equivalent of nearly 100 regular attacks that you’d need to land before the next life siphon attempt to make VP be worth more healing.

The distance only spreads further if you include non-trivial amounts of healing power, or the edge scenario of life leech (Downed 1).

So I’d say use bloodthirst. It looks like vampiric precision is more for builds that can only afford 10 in Blood Magic and thus don’t have vampiric, or aren’t taking a dagger.

Awesome answer! Thanks!

As a MM with Vampiric Master, I pick Bloodthirst every time. All those little nibbles from my pets adds up!

Couldn’t both be taken?

First off, Bloodthirst is only a 20% boost.

Second, while Vampiric Precision does more independent of skills (assuming a 50% or better crit rate), as soon as you factor in a skill with a siphon component, Bloodthirst flies away at an uncatchable rate. With 100 healing power (minimum to have Bloodthirst), Life Siphon heals for an additional 61.28 per pulse.
