4* challenge for the win yeah!
@Muchacho you’ve started a movement 
Linking to my plan…
Went with my back up plan:
Proteus 2 +6/ Kiril / Kashhrek costume / Proteus 2 +19 / Skittleskull normal
- +19 Proty supported with Lvl17 mana troop to charge in 9 tiles
- Kash protects +19 Proty and Kiril, so I have my mana block, healing and a direct counter to boss Ulmer
- Skittles’ attack debuff makes a good backup just in case
- costumed Melendor is a bit redundant vs. Kiril, so I went for Kiril as the attack buff would help - this team relies on tile damage and stalling. Decided a 2nd Proty would make more sense.
Benched 5*: Sartana, Isarnia
Benched 4*: Melendor costume (as reasoned above), Sabina (nothing to dispel, weak color to 2 bosses)
Made it to boss stage with all specials charged, and my core 3 had double HP. Wow, costume Kash is a beast - I’m glad I maxed him. Alas, ran out of purple tiles after a few turns and Ulmer and Quintus got to fire. poor backup Proty and Skittles died… but the middle 3 stood strong. Ulmer died first to a cascade of Green tiles. Balthy fired again, but got killed by tiles soon after… and finally, Quintus.
My middle 3 were never in danger of dying, thanks to good old Kash! Never imagined I would ever type that…
Wizard emblems bring Sartana to +6, and targetting to get her to +7; I usually use her on offense with Proteus, Tibs and Seshat and prefer her in costume (as that extra up-front OOMPH is often the difference between murdering a dangerous opponent before they can fire).
Sorcerer emblems in the bank. Might bring my Sabina 2 up to +20 as well… Skittles is the only other option, and Sabina 2 still gets more use in my mono Purple 2nd war team, while Skittles sees use mostly in Class Quests and world map.
Purple Trainer to dupe Sartana’s costume.
