Aside from the Story (or World Conquest) mode, Fantasy War Tactics also offers players a chance to prove their team's worth by battling other players. The Battle menu currently offers 2 game modes, the Battle of Honor and the Dimensional Breakthrough.
Battle of Honor
Battle of Honor is a PvP-oriented (or Player-versus-Player) game mode where you put up a team of 4 heroes to battle and climb through the ladder determined by your Honor Points. Wins will increase your Honor Points while defeats will incur losses. To participate, you must have at least 1 Honor Sword, Honor Swords recharge every time up to a cap (7 by default). Participating in the Battle of Honor will give you rewards.
Battle of Honor is formatted into Seasons, each Season players will have their Honor Points reset to 1000 and given a chance to climb the ladder up again. A season lasts for a week ending on Sunday and every start of a new season, participants are handed out the rewards from the previous season.
Rules
There are certain limitations in the Battle of Honor, these are the following:
- The first turn is determined by random before the start of the battle.
- You must defeat the enemy team within 20 turns, being unable to do so will result in a defeat.
- You cannot use Lord Skills (i.e. Hellfire, Grace, Heal, and High Morale).
Rewards
Battle of Honor rewards players who participate on the season. You must participate in at least 1 battle to be eligible for the rewards. Rewards include Gold, Crystals, and Honor Medals. Honor Medals can be exchange to the Honor Shop for 
Belle, 
Nox, and/or 
Persona hero genes.
Dimensional Breakthrough
Dimensional Breakthrough is also a PvP (Player-vs-Player) game mode wherein you will battle through a series of battles called Virtual Stages.
Rules
There are also rules for Dimensional Breakthrough, these are the following:
- Unlike Battle of Honor, you may use Lord Skills (i.e. Hellfire, Grace, Heal, and High Morale) during the battle.
- Heroes will not heal up completely after the stage, they will only recover a portion of their HP and MP for the next battle.
- Once a hero loses its all of its HP, it cannot participate anymore in the breakthrough.
Reward
Rewards for Dimensional Breakthrough are given out after a stage. Rewards include Gold, 
Lena and/or 
Fruel Hero Genes, ancient coins, energy, and crystals.
Strategies
- Dimensional Breakthrough requires no energy to enter but will often reward energy. By expending your energy first, then coming back to Dimensional Breakthrough will allow you to go back and farm those genes in the main map.
- Dimensional Breakthrough also allows you to check the map and enemy placement before actually attacking as quitting after checking the map results in no loss other than your progress in that stage.
- A common practice that is also possible is to charge your Lord Gauge in other dungeons, enter a hero on the DB stage, use Hellfire, then let the enemy kill your hero. Repeat the steps until the enemies' HP is low enough to be whittled down by a strong team. Best on Stages past 5.
