Wood Style – Deep Forest Wall

Before:Generates a Shield based on 50% of the unit’s Resistance base attribute on a selected unit, will also receive 40 Chakra points.

Now:Generates a Shield based on 50% of this unit's Resistance base attribute to a selected unit on the same column as this unit. Moreover, the player will also obtain 20 Chakra points for each unit in the same column as this unit.

Actually its more... 60 chakra from 40 if u place 3 ninjas in same column
