There is one ach. left between my and my red proto "
Less-Rabi".  I am at my wits end.  I have tried multiple strategies from quick burns to timing of ints on slow burns to even bugging it and repulling.  I am asking...no, I am begging for help from anyone who has a cut and dry method.

Currently this boss is bugged, allowing it to transform after it's dead, makes this achievement 
very hard to get.

I´ve had my frustrations about the pains of daily life
I´ve tasted degradation and found the lace and candle light
But we have the weights we have the measures of our days and nights
I´ve had my frustrations but now I´ve found my place
And you will make it
But only if you run
ALL GLORY TO THE HYPNOTOAD!
