Putting all my red 5* here:
- Mitsuko+19 (870pwr - 726-874-1565)
- Costumed Elena (794 pwr - 845-588-1494; regular Elena at 4.01). Yunan+19 has the Fighter emblems.
- Grazul (770 pwr - 628/817/1406) - Ariel+19 has the Cleric emblems.
- Zimkitha (769pwr - 714-681-1454) - Alberich+19 has the Druid emblems.
- Azlar (757pwr - 793-607-1322) - Kageburado+20 has the Barbarian emblems; 96 extra emblems without a hero.
- Scarlett+19 (735pwr - 895-558-1142) - high firepower for events. Probably will be replaced (and stripped of her emblems) after Regular Elena is maxed and received Fighter emblems to surpass that 895 attack stat.
Mitsuko is my #1 red hero, for her flexibility, being good against all green, in addition to blue heroes with attacking specials (hello Finley). Zimkitha is my second red hero, again for her jack-of-all-trades character. Azlar and Elena are damage dealers (DoT and Riposte are additional skills). Grazul is very good alongside Zim. I use the Graz-Zim-Mitz combo against Telluria.
Unfortunately, I don’t have Gravemaker.
Ursena would be a better tank, best on defense. But that’d depend of who do you have in your roster. I don’t have Ursena, but my purple 5* squad is quite nice (Kageburado+20, Seshat+19, Alfrike+12, Kunchen, Hel and Sartana maxed; Alfrike 4.12, maxed Costumed Rigard and Tiburtus and Seshat 3.70).
