Way

Support plugin "gravestone".

Group of players

Peaceful players;
Players who have a thirst for PVP;
Players that kill indiscriminately.

External differences

Peaceful players - with a white name above his head;
PVP-players - with a purple name above his head;
The Killers - with a red name above his head.

Description

* Its configurable.

In the beginning, all composed in the «Peaceful players».
When you hit another Peaceful player or player mode «PVP» - you also go for 30 seconds in the «PVP».
If you kill a player of the «Peace Group», you become a «Killer». Being in the «Peace Group» and attacking «Killer» - you do not go in mode «PVP».

For each kill «Peaceful players» - you karma falls by 10 points.
In order to go back to the «Peace Group» - you have to kill sheep, cows, zombies or skeletons.
For every mob - your karma is made up by 1 point.
If you die as a «killer», that karma is made up by 10 points.

Differences between groups

Peaceful players - dying from the other players do not lose experience, do not lose the armor, 95% do not lose things from the inventory;
PVP-Players - dying to lose everything;
The Killers - dying lose everything. Killers superimposed effects: Slow, slowdigg, weakness. Effects persist until the karma is less than zero.

Commands

/pvpstatus - about your status;
/pvpspawn mobName [level [count]] - spawn mob in current location (for Op).

Enabling rpg mode caused an uproar on my server. Be careful.

Disabled by default, you must change the setting rpg.enable.
Each creature has level.
The farther away from spawn in the world, so it is more. Each 100 meters = +1 level for mobs.
In the Normal world level begins with 1, in Nether with 25, with 50 in The End.

Damage in «RPG»
Entity with Y level has entity with X level: damage = default_damage * ( (Y / X) ^ rpg.difficulty ).
It is spread on the players.

Experience in «RPG»
Experience falls from mobs killed by you, only if the difference in level is not more than 5 (Hello, Lineage).
