The ''Reduced Bacteria Strength Needed'' (RBN) effect changes how many [[Resources#Bacteria|'''Bacteria''']] are needed to take down a [[Planets|'''planet''']].

For example, if a player attacks a planet with 100k Bacteria and has +100% bonus to Bacteria StrengthRBN, it will be just as effective as attacking with 200k Bacteria and +0% to Bacteria StrengthRBN.

===NB!===RBN does not reduce the price of [[Colonies|Bacteria Strength Colonies]] and [[Upgrades#Bacteria Upgrades|Upgrades]].  RBN can be increased via '''[[Planetary Research]]'''.
