Also happened to me when i sac'ed some of my 5* eddies that i dont care about, got skill shards, not a problem since i need them for rainmaker, but with the the tier 7 i also got myself a vortex fill, which netted me another 5 skill shards and 10 assassin souls, no 4*s or 5*s ofc
Funny that i got 3 skill shards in the past day, from skull quests, so i guess I technically did an ultimate sac?
Other than that, i can say the game is pretty free to play for me, the immortal (or was it called somehing else) shards where a great help for free players (got my rainmaker from it!) and the events while grindy and stuff like that help you become better, but i have to say this event is total Bullshit, 20 rare souls, for 1 legendary green bomber boy?!? What a deal bois! Never gotten anything except from a legend except green bomber bois for some reason, i can complain about that roight?
Other than that i am trying to play this game more. Shit event
I give it a green bomber boi/10
