I have a 5* Unduped Loki, R2. And it's very difficult without him being awakened. I have to risk more basic hits and getting evaded and counterattacked too frequently. If I had awakening, it would be easier. I have a max 3* ranked duped but block damage is too much so in practice, i'm at a loss. I've spent 900 + units (wasted Battlechips rewards) I give up! I would actually pay someone in units to do it for me now.
@Infinite Warlock I completed this about a month after posting. I got lucky and got a Medusa. I just got her to R3 Max as 4* and she did the job. I managed with 2 tries. Goodluck. Now I'm stuck at 6.2.2. WAIT till you meet Mr Sinister.
I have dup r5 5* void and r4 5* medusa but i cant kill ultron and now im stuck at final boss. I lost 700 units already. Im getting depressed already. Can someone please help me? I will gift u ggc on xmas if u can kill this ultron. 🙂
Arni2 thanks brother, it's been 2 days that I stuck in there, out of resources for awhile, but I'll be trying your method once I was ready. Thanks a lot for your useful tips👌👍
