Not here to yell (BUFF BUFF) just here to express how disappointed I am, at new years hashirama (didn't buy him yet so dodge a bullet). So here what I TAUGHT he did,
Chase would stack on pre-chase, such as giving that 20 chakra increase then if he chases again getting 40 (but nope it locks at 20 on that ninja), Then that only last that round I at-least taught it would last 2 rounds minimum.

Another thing I taught since i seen other units (like genma who can literally give everyone a permenant 5 extra chases even on summons and even keeps going after he dies)
that his extra chase that random would at-least last 2-3 rounds not just that round then bye bye.

personally was just sadden by it but such is the "balancing' life .
