Early Rounds: It is recommended to deploy 2-star Warrior pieces and try to activate Synergy Warrior (3) effect. If you have both Tusk Championand Werewolf, or Redaxe Chief and Swordman or any other Warrior pieces that can activate Beast or Cave Clan Synergy effects, you may deploy them on the Chessboard to earn a winning streak in the early rounds. If you still have Gold left after piece purchase, you may Buy Exp with the rest Gold to level up to Lv.6.
Mid-rounds: Upon reaching Lv.6, it is recommended to maintain Synergy Warrior (6) effect and deploy pieces with better quality and higherstars on the Chessboard. Meanwhile, stop buying Exp and try to have 30 Gold at hand instead. If you have more than 30 Gold however, you can still Buy Exp withthe exceeding part to reach Lv.8 (try to always keep 30 Gold at hand to earn asmuch Interest as possible). Besides the required Warrior pieces, it is recommended to purchase Siren as long as it occurs in your Store. If you arelucky enough to rank up your Siren to 2 stars, unlock 7 piece slots with your Gold,and deploy it on board to earn as much Gold as possible with another possible winning streak.
Later Rounds: After Lv.8 has been reached, it is recommended to keep more than 30 Gold at hand and meanwhile refreshing the Store for useful pieces. During your search, try to increase your Magic Resist by activating Marine (2) Synergy, and try to get Tsunami Stalker while ranking up your core pieces on board.
