i've already finish the challenge 1 and 2. the challenge 3 is to hard how can i finish it?

this is the way how i beat challenge 3:

I used the gautlet of zeus to defeat all the enemies except the bats by using the
"R+triangle" move and "hold circle" move..........For killing the bats,i use the dual
swords and do "R+triangle" move to kill most of the bats......
