I updated the wiki page. Neither the previous page nor the old officials were accurate. It uses SL:B skill not ranks and it's at seed 1.

https://gswiki.play.net/Vigor_(1616)

Additionally, the spell-list.xml in lich should look something like this:


<spell availability='self-cast' name='Vigor' number='1616' type='utility'>
<duration span='stackable' multicastable='yes'>20 + Spells.paladin</duration>
<cost type='mana'>16</cost>
<bonus type='constitution'>[10, 4+((Spells.paladin-16)/4).floor].min</bonus>
<bonus type='health'>((Spell[1616].constitution + Char.con[0] - 50) / 2 - Char.con[1]) + (Spell[1616].constitution * 2) + (bonus = 0; [1,3,6,10,15,21,28,36,45,55,66,78,91,105,120,136,153,171,190,210,231,253,276,300,325,351].each { |n| bonus += 1 if Skills.to_bonus(Skills.slblessings) >= n }; bonus)</bonus>
<message type='start'>The blood in your veins thickens and pulses with renewed life!</message>
<message type='end'>You feel slightly weakened as the blood in your veins thins\.</message>
</spell>

I don't think this is a situation of intermediary benefit; it looks like this is very nearly Seed 1 skill but not exactly. I went from 24 ranks to 25 ranks and expected to see +1 health, but instead needed 26 ranks.

Maybe 5 skill is enough to achieve +3 HP. That is to say, compared to Seed 1, it requires less skill to receive the benefit on the low end but more as you progress higher?

NIR to confirm.

I'm getting 38 HP. 25 base from spell ranks, and 13 from SL:B. With round(sqrt(2*SkillBonus)), I should be getting 39 HP.

I added both tables, the seed 1 SL:B and round(sqrt(2*SkillBonus)) to the wiki.
