This is correct , I also see the upgrades as soon as I logged in atlasreactor homepage and they ' re 50 % off . <| sep |> Wow that ' s some neat observation . After 20 runs I still don ' t get the HP bar thing . Now that you mention it , I think most teams are screws when u see the . and compound damage laser . I guess that happens when we fail to burst first head during the 1 chain window and subsequently do 0 damage to 2 nd and 3 rd head , and thus allowing the 3 head to do the ultimate laser compound damage , which I think also decreases your block regeneration . Because somehow even after surviving the laser , I feel like always lacking blocks to healbuff back . Then for some weird reason the boss still died when the 1 chain window came out again . I guess that ' s when the 1 st head is vulnerable again , and thus 2 nd and 3 rd head .
