Death certificates is a simple plugin that gives the player a certificate confirming that he or she killed that player. You can even redeem the certificates for a little bit of money if you have Vault.
desthcertificates.relaod - Gives you access to the /deathcertificate reload command.
Currently, you can configure the name of the certificate and multiple lines of lore. At the moment, 4 placeholders can be used: %player%, %killer%, %time% and %money% Color codes can now be used in the configuration. Please note that currently %money% only works in the RedeemMessage and the other placeholder don't work in RedeemMessage yet.
Code (Text):ItemName: '&4Certificate of %player%''s death'
- '&fAt %time%, &4%player%'
- '&fwas killed by &4%killer%'
RedeemMessage: '&2You have redemeed a Death Certificate for %money%'
I would like to thank @Talion for the economy idea.
