The death penalty

[Darklake]

No, it's not a thread about sending Fourthmeal to the chair :-)

Just an idle musing, how is the XP loss on death calculated? Is it a fixed amount for the level, or is it more based on "the equivalent of x white con mobs". I was wondering whether (for example) two level 30s, one a troll SK, the other an assling warrior, both eat a death, would the troll SK still have to kill more level con mobs to make up the loss in comparison?

I don't intend this to degenerate into another OMGWTFLOL right or wrong discussion regarding penalties, just more interested in the maths behind xp loss upon death.
