7* chewbacca Event

Modding appropriately is the Key

. If you stay with a Boba lead you will need a lot of potency and some RNG. The Bossk Zeta lead made the fight very manageable for me after trying 50+ times with a Boba lead a bit the bullet and zeta'd Bossk's lead then remodded the team for higher protection and no focus on potency. I got it in 3 tries, the first 2 tries were really bad RNG, but the third try I got very lucky and Greedo hit chewy with his basic 5x in a row. This was possible because I put all my fastest crit chance set mods on Greedo, his crit chance was over 70%.

Run Down on mods (use your best speed secondary stats speed is king)

Bossk with Zeta lead gear 11, All Health set mods, Protection circle, Protection Cross, Protection Triangle, Speed Arrow.
Greedo Gear 10, all Crit set mods, Protection Circle, protection Cross, Crit Chance Triangle, Speed Arrow
Boba Gear 12, Crit damage and Crit chance sets, Protection Circle, protection Cross, Crit Damage Triangle, Speed Arrow
Zam gear 10, Speed and health set (could use crit chance but my best crit chance mods are used on the above). Protection Circle, protection Cross, Crit Damage Triangle, Speed Arrow
Dengar Gear 9, What ever the fastest set you have left speed/offence set preferred, Protection Circle, Potency Cross, Crit Damage Triangle, Speed Arrow.

Note Dengar actually needs some potency to stick a stun and he shouldn't take too much damage once he is sheathed.
Note I needed Dengar to Stealth to prevent R2's smoke screen to have a chance to pick of the guys in the order I wanted.
