My HC seasons crusader has officially turned into a 'zoosader'. I found the shield that grants double Phalanx summons and the ring with 200% more Phalanx time (pets stay out the entire time). The results are pretty hilarious - this is like playing a witch doctor.
Can't get the ring or the flail but it looks like ridiculous fun. One of the other sader I run with in the guild uses stampede and it works great with the archers. Would love to finish this build.
