ToME: the Tales of Maj'Eyal

Similar to health, just for stamina... ?

Sounds simple, and somehow it seems stamina is increased less by willpower than mana is... This may be just to be able to sustain some of those really big sustains like slow motion...

Mana talents usually cost more than stamina talents (archmages have multiple >=200 sustains).
Slow Motion is however too costly and has been disminished to 80
