Corvin is a raven? Well, I suppose he is strong. He is!
Here's what I *discovered.....*
Alae Custodiae - Fill the Party Gauge by 16 for each critical hit delivered. This skill synergises well with his third skill . I have Corvin at about 50% critical chance, so a good amount of his Driver Arts will crit. To add to that, most of his specials are multi-hit attacks, so that helps him fill up the Party Gauge even further. Corvin's ability to keep the Party Gauge filled up makes him work really well alongside Shulk.
剑螳 - Boosts recharge for Driver Arts by 2.5 when you evade an attack. This skill is what really brings all of Corvin's abilities together. He'll constantly be evading attacks because of Ensis Lucis (which increases his evasion rate by 25%), which will help to recharge Driver Arts extremely quickly, especially when pouch items that boost arts recharge are being used. At this stage, Corvin essentially lets you spam arts, which is an ability that's pretty much limited to attacker Blades with critical recharge arts.
Fuga Daemonum - When landing a hit, restores 10% of damage dealt as HP to the party. This isn't exactly the strongest Blade special out there, but it gives the party a little more survivability, which can really tip the odds of a tough battle towards your favour.
Lacerna Noctis - On using a Special, has 100% chance to purge 敌人 rage status. It's similar to Shulk's Monado Purge Special, but instead of getting rid of an enemy's awakening state, it gets rid of their rage. Many of the strongest 敌人 in XC2 become extremely dangerous when they're 狂暴化, but Corvin gets rid of this problem entirely.
Ex Tenebris Lux - On Special, Driver receives afterimage, evading next 6 attack(s). Not only is this the coolest looking lvl 3 special in the game, it also helps you evade even more attacks, which means that you get a recharge on your arts.
