Best time to max out Stamina (Available Ability)?

[IanTheWizard]

In a video which shows a player killed black trolls in Suslanger in multiplayer, the player said his character "reached 1m exp". From the video, we can see his character has 156 Health and 417 Stamina. (He boosted up the Health to 235 by using Strengthen spell)

Today, my character reached 1m exp (1001640), too. But he has only 130 Health and 217 Stamina.

So apparently, that player's character has chosen Health and Stamina from Available Abilities before.

I know that, if I max out my Stamina (Available Ability) now, my Stamina will become 434 (217 x 200%) and will be able to kill black trolls like that player. But I'm not eager to kill black trolls now because I'm currently farming money to buy Teleportation spell.

If I understand correctly, the later I max out Stamina (Available Ability), the more Stamina I net earn. For example, if I max out Stamina (Available Ability) when my Stamina is 100, I net earn only 100 Stamina (100 x 200% - 100); but if I max out Stamina (Available Ability) when my Stamina is 300, I net earn 300 Stamina (300 x 200% - 300).

If my calculation is correct, I think I can max out Stamina later so that I can net earn more Stamina. Please correct me if I'm wrong.


== Edit ==

Regarding the Health of that player's character in the first video, I watched his second video again and noticed that his character's Encumbrance is 216. So I think his character has chosen Strength (Available Ability) rather than Health (Available Ability) in the first video.
