Whats energy of salvation?

I'm kind of a noob to it too but it's either the term for rested experience or the bonus bonus experience you get after not playing for x amount of time that it gives you as incentive to play. it also gives like 5% better drop rates or something like that.

It gives you extra Experience and additional droprate chance.
Without gold pack I recall the Experience rate was 40%, and with 60%?

It is not time based, but exp based. If you have 100% when logging in, killing a mob might bring you down to 98% etc etc.

Logging out in a studio/house etc will make you fill this bar quicker.

You just combined both energy of repose and energy of salvation.

Energy of SALVATION:

If your progress in level is rather slow you will get an extra boost to experience (20% additional exp I think and maybe increased drop rate)

Energy of REPOSE:

If you log out for a while you start accumulating this guy. 40% additional exp, up to a preset amount that changes as you level, and some % increased drop rate. I can't remember if it is like 5%-15% increased drop rate....I don't remember, but I could log on and check.

Repose is a 10% increase to drop rate.
