Bigger Challenge,makes the opponent grow bigger in the beginning.You will have to be lower level than your Opponent or similar level then you get the 3option after you encountered an enemy.1. "bring it tiny" Makes the opponent bigger in the start of the combat.2. "You'll have to fight me first" makes the opponent slightly bigger.3. "i don't think i will" doesnt make the opponent bigger.Choosing the first 2 options gives you an "Ego Boost" which gives you a XP multiplierer and it also makes your cock bigger.
