A truly dedicated warrior is always ready to fight, especially if he hates his enemy as much as Magmars hate Humans and vice versa.
If you are a truly dedicated warrior you should come to help your commanders at 01:00 on Thursday morning. Be well prepared and expect a hard and fierce battle, your enemy will not be sleepy and in this battle the commanders will allow you to call your summons even after the battle becomes a Great Battle. You can receive a large Valour reward when you join the battle of your commander.
The PvP Tournament with Summons is for all warriors up to level 10. Access to the Malleable Badlands will be granted Thursday morning, 01:00 Faeo time. The Commanders will already be fighting and you should join their fight. Go to the Baurvill Hamlet and the Settlement of Faytir and pick the Malleable Badlands as your destination.
