The only issue with [Dante] is how sluggish his abilities are. Would recommend using Madurai and archon shards for at least 150% total casting speed. No need for additional strength like Molt Augmented, for example. Pageflight is necessary to one shot eximus and thrax at level cap. To make full use of [Equilibrium] need [Synth Deconstruct], which can easily be triggered by [Arc Coil]. It can also proc [Archon Stretch]. [Arc Coil] has a small range compared to Dark Verse and Tragedy, so would also use [Helstrum] to tag enemies for [Equilibrium] from far away. Can use [Xata Invocation] and [Khra Canticle] on the [Grimoire] for even more energy income.
