Sub: Queen Penn

Need around 55-60ish armor on Penn with over 170k hp.
Had one sword at 105 and two at 95.
One spirit at 105, two at 75.
And three level 12 vengeance, 1 lvl 12 advantage, 2 lvl 11 advantages.

I got between 85 and 95 with 5 heroes standing using either of the two forms in the replays.
