Repost cause they removed it...

So, lemme give you the details about the entire situation.

As you can see my stella is perfectly matched. There are three waves. Wave 1 starts with 2 Harte Knaves and after a few seconds a frenz!ed Harte Knave joins, which I defeat in 21-22 secs, not within 20 sec, which dissipated the frenzy energy.

Wave 2 starts for me when 2:10 mins is left, with a blue lion thing with 2 protocore shields. Few seconds later a same blue lion but frenz!ed one joins. I defeat the latter in 23-24 secs, within which the frenzy energy dissipates. I defeat wave two with only 50 sec left for the boss.

The boss is a purple electric dragon. I very desparately manage to take off 1 whole HP bar within this time. There are still 3 more HP bars left when the timer runs out.

Now, what am I supposed to do. Because even if I increase the stats, I think I'll probably have to defeat both waves within a minute so that for the boss, 2 mins are left for me to defeat.

But for people who have already passed this level, is there any suggestions? I've been stuck here for almost 2 weeks. I really need to get through it.
