At this moment, for pilar Karok - basicly atacking with proper delays so you absorb enemy boss attacks while taking no damage. Main combo is i would say LRLRRRE (a tleast for me) and as you probably see - it's kinda big and slow combo, it lasts for like 2 or 3 enemy boss attack patters - but he can do it thanks to absorb unlike any other character.. He does not have proper block - absorbing with attacks is way better than absorbing with his roll. Basicly he is all about timing and spacing his attacks properly.
For cesus Karok... well i never played him too much, never cared ^_^.
