Chaplain is a bit underwhelming in it’s current form, so I would suggest to strengthen it by giving the skills new attributes.
Attribute 1: Increases AOE Attack Ratio by 1 per attribute level. (Max level: 5)
Attribute 2: Increases crit rate by 20 per 1 attribute level. (Max level: 10)
Attribute 1: Gives you immunity against every debuff and status ailment for half the time Paraclitus Time is active. (Max level: 1)
Attribute 1: Lates Rites spawns an additional holy attack line for every Chaplain buff that is currently active in your buff slots. (Max level: 1)
Attribute 2: Your current max stamina amount is added at x100 to the holy property attack amount of Last Rites. Example: Your max stamina is currently 25, so 2500 holy property damage is added to Last Rites. (Max level: 1)
