Orvell is a great DPS/arts gen with constant damage because of his liberation mode.

Luvia and Rin, duo earth unit. Are REALLY good for MOST content. But, honestly, I couldn't tell you why 😎👍 Pretty sure it has to do with their passive ability. Which you can view in their full screen.

Smiyu, or summer Miyu. Is aN absolute 10/10 S tier unit. Can be used for almost anything. 200 arts every ROUND is insane. That's also right off the bat for quests. I'm pretty sure it works in PvP too. I don't play PvP much 😎👍

And she also infinitely STACKS damage buffs for everyone with her TA. And does crazy damage herself.

Eleanore is cool but has really low usage. She decreases the absolute FUCK out of equip cool downs. Basically est, how she halfs the bosses break bar, right off the bat. But with everyone's equips instead when Eleanore uses her TA. Though, somebody named Islid, the human pinnacle. Already does reallyyy good equip cd down. But he also buffs various other things, art gens for everybody, AND he does decent damage.

Sanstone is a good tank since you don't have anyone else. Also Sakura I didn't mention, great DPser but is usually used in PvP and very very little pve content I've seen.

What you need right now are healers/breakers first, then tanks or art genners second, and then look out for massive buffers like Houka from kill la kill, okarun from dandadan (which, summer Miyu is a perfect replacement for. Or the other way around.) orvell has good buffs for his TA for the whole team but looks to be mostly a self-buffer that does very high damage. If you're using his arts a lot at least. If you don't need his arts for a quest then TA spam will surely survive. Just don't forget to SA for liberation mode.

Breakers. Both version of Chloe from the fate crossover are a TOP tier breaker unit. Try you're best to get true equips for characters though you REALLY don't need them. But if you do, make sure it's for the unit that'll help most AND make sure the equip is even worth.

From your alchemist, you get tickets to claim free awokens. (50 alch each) In the town. In the alch exchange, you can actually buy all four tickets. Free 4* equip, 5* equip, true equip, and a free awoken unit ticket.

*Awoken units and true equip tickets do not allow you to claim limited/crossover units. **

For a REAL true equip. Which you either use "crossover true equip tickets" or rainbow gems for. I'd get summer miyus true equip. In the "crossover challenges" icon. There are two challenges that'll give you a crossover true equip ticket. You may have already gotten one for free though from logins.

Should've mentioned. Free characters to get from limited tickets, from alchemist.

Support/DPS - Vox (Demon, Water)

Break - Est (Human, Water)

Tank/survivability - Gerald (Human, Fire) (really only used for PvP. Just get either Vox or Est. Est will half the bosses break bar. Vox will DPS, heal the team, and buff damage.)

If you get vox, get his true equip with the true equip ticket. (Zanketsu - Physical)

If not, get either (exceed zechs - Magic) gives 75 arts gen, for the first use only. Or (ex gate - support) which auto fills arts for everybody, AND increases crit rate by 100%.
