Next game is in the western part of the district.  You will have to take some flags and move them to the base. Your opponent will try to stop you. 
Healing Potions will be handy here. At the beginning of each round, run towards the target. From the edge of the building under which the flag is located, simply jump down. You will loose some life, but you will be first for sure.  Go back onto the roof.  You should be fast, because the enemy can take the flag at any time.
The party is not very difficult, you can always take the flag from the opponent.  In addition, you can use their aversion to water - when you will jump into the water the chase will be suspended for a few seconds.
