(Missable!)
Dante has Skills available for purchase in the game for his Alastor and Ifrit weapons. A grand total of 26,800 Red Orbs are required to purchase every one of them. Both only have five main upgrades, with further upgrades available for two in each category. In all honesty, this isn’t a difficult trophy, as there aren’t too many upgrades you need to get. Anyway, here’s the upgrades:
ALASTOR:
Stinger Lv. 1: 350 Orbs (Stinger Lv. 2: 1,400 Orbs)
Round Trip: 1,550 Orbs
Air Hike: 4,000 Orbs
Air Raid: 750 Orbs
Vortex Lv. 1: 1,150 Orbs (Vortex Lv. 2: 2,400 Orbs)
IFRIT:
Rolling Blaze: 3,450 Orbs
Magma Drive: 500 Orbs
Kick-13 Lv. 1: 700 Orbs (Kick-13 Lv. 2: 2,100 Orbs)
Meteor Lv. 1: 900 Orbs (Meteor Lv. 2: 2,700 Orbs)
Inferno: 4,850 Orbs
