Instead of losing all skilltree levels when players die (default setup), how bout allowing modpack/server owners to adjust how much skill levels are lost upon death?

For example, when a player dies:

0 ~ 50 random points per death

You can change loseStatsMultiplier in the config or set them per stat

yes but ranges are
0.0 ~ 1.0

So when players die, they lose all of everything.
Where as, losing a little by little after every death is the goal.
