Hi, I cant seem to get the pernalizedeath working here is my config:

    PenalizeDeath: true
    PenalizeType: true
    PenalizeAmount: 15.0

This means that 15% will be taken off correct?
I have set up the permissions and still cant seem to get it on
I was also wondering how to set a percentage gain when you kill a player instead of a set amount

Player:
    Coin_Minimum: 20.00
    Coin_Maximum: 20.00
    Coin_Percent: 50.0
    NoReward_Message: ''
    Reward_Message: '&7You are awarded &6<amt>&7 for murdering &5<crt>&7.'
    Penalty_Message: '&7You are penalized &6<amt>&7 for murdering &5<crt>&7.'

Im using the latest Bukkit and Pex,
Thanks :)

My setup with PEX works with this in my permissions.yml:

groups:
    default:
        default: true
        permissions:
        - ecocreature.reward.*
        - ecocreature.gain.*
    Admin:
        permissions:
        - '*'

Regarding percentage gain, if you mean that a player gains a percentage of what is in their account, then there is no support for this feature.
