Since I believe this is where most theorycrafters and min/max’ers live I have a question/request. I need a formula which will calculate HP for light, medium, and heavy characters when downleveled.

I have two known variables: current level and vitality stat. How can we process that into HP?

Based on the wiki http://wiki.guildwars2.com/wiki/Health

The health is increased in tiers. You’d have to formulate based on those tiers.

var L = level;
var V = Vitality;

health = L* 28;
if( L > 19) { health += (L-19) * 42; }
if( L > 39) { health += (L-39) * 70; }
if( L > 59) { health += (L-59) * 70; }
if( L > 79) { health += 70; }

health += V * 10;

This above formula would be for high health (warrior, necro)
——————————-

health = L* 18;
if( L > 19) { health += (L-19) * 27; }
if( L > 39) { health += (L-39) * 45; }
if( L > 59) { health += (L-59) * 45; }
if( L > 79) { health += 45; }

health += V * 10;

This is for medium hit point (Engi, ranger, mesmer)
—————————————————————
health = L* 5;
if( L > 19) { health += (L-19) * 7.5; }
if( L > 39) { health += (L-39) * 12.5; }
if( L > 59) { health += (L-59) * 12.5; }
if( L > 79) { health += 12.5; }

health += V * 10;

And this is for lower hit point professions (Thief, ele, guard)

Codes I use in gw2dungeons.net: http://pastebin.com/PpfGTjzB

Health = base health (profession) + vitality health (vitality).

Base health can be calculated by using the formula Kirin gave above (just check numbers from wiki as he copypasted bit too much).

Stat scaling is based on base stats. You can check wiki how many base stats you get each level. Then calculate base stats for wanted level (for example level 30 has 206 base stats) and divide by base stats at your level (level 80 has 916 base stats). For example 1000 vitality would be 1000 * 206 / 916 = 225 vitality at level 30.

To get health from vitality just multiply it by 10. For example 225 vitality gives 2250 health.

Perfect, after a bit of coding here’s the result:

Shows allies around you (<6,800 radius open world, and unlimited for party members) and their Vitality deviation from base. Good way to guess people’s traits (a lvl 80 ele with 200 vit deviation most likely implies he traited 20pts in water), and their gear (36vit most likely means a cheap backpiece), and obviously easily spot fellow pvt’ers

Now, at lvl 80 traiting 200pts results in +200 vitality. When downscaled that is not the case anymore. Looks like that’s the next thing to figure out so I can add a +traitPoints deviation from base. Doesn’t look like I’ll be sleeping tonight XD

Can you elaborate more? Stats scale same regardless of source so I don’t see what’s the issue.

- At lvl 80, +100 vit = 10 points in vit line.
- At lvl 65, +48 vit = 10 points in vit line.

Of course I know this because I looked at my hero panel, but what if I don’t know how many traits player has spent. For example,
- At lvl 65, +230 vit over base = how points in vit line?

Obviously, both lvl and vit-over-base will be variables.

You seem to have messed up something.

With level 80 character I reseted my traits, went to lvl 66 area and put 100 trait points. I got 73 stat points which is exactly same as ratio between lvl 66 and lvl 80 base stat points.

Then I took my lvl 67 character, reseted his traits and put 100 trait points. I stayed at city so he didn’t get downscaled and he got exactly 100 points.

To calculate stats from traits correctly you need both original level and downscaled level.

I found the culprit – I was playing with traits using a lvl 69 alt. Using a proper lvl 80 char everything calculated as expected.
