Dust 514: Passive Skill Points
Passive skill points
In Dust 514, each account can have three characters but only one can benefit from Passive Skill Points gain while you are not playing the game. It is currently 1000 per hour or 24,000 per day. That works out at 8,760,000 per year.
Players can purchase using Aurum from the Playstation Store, a 'Passive Skill Points Booster' which increases the rate of passive gain by 50% or 36,000 a day. That's 13,140,000 Skill Points a year.
Passive Skill Points Booster's come in 1, 3, 7 or 30 day versions, with the latter being the better value.
