Finished the event

On the last map pray to the RNG gods really hard to get the uppermost boss

Bosses:
Uppermost: 2 Finishers and a Crimson Winged Moth lvl42 - relatively easy
Right: 2 ???lvl Caterbros - a relatively healthy ~35k squad can take them down
Middle: ???lvl Ancient threat - Only boss that can give you trouble but two squads can take it down (or 1 squad at around 45-50k strenght)

first 3 were really easy, 2 attempts on 1 and 1 shot 2 and 3, decided to go for only 2* on the third on the first try and was glad I did, my teams are not yet strong enough to handle the double ?? boss team. Be sure to lvl your teams 2-4 quite high or you will not live through the last map. Suggest 30k+ power on all teams, 25k didn't cut it lol.
