1. Troops in the battlefield won't suffer any casualties. Injured troops will be sent to the Infirmary. The Infirmary has no capacity limit. Healing your troops doesn't cost any resources, but you can use Speedups to reduce the healing time. All your injured troops will be healed when you leave the battlefield.

2. Buildings will burn much faster within the battlefield. If you fail to defend your City and extinguish the fire in time, your City will be moved to the Safe Zone.

3. After entering the Tundra Arms League battlefield, you must leave the battlefield first before joining Foundry Battle, Frostfire Mine, Canyon Clash, and Frostdragon Tyrant.

4. The cooldown of your Battle-type Pet skills will be reset at 00:00 and 24:00 UTC every match day.

5. Buffs from Battle Techs, Alliance Techs, VIP stats, Chief Gear, Hero, City Bonus items, Skins, Pet Skills, Position Perks, and Experts will all take effect in Tundra Arms League.

6. You can watch the matches of all Zones if the Tundra Arms League is held in your State.

7. If you leave the battlefield halfway through a match, you can only re-enter after 12 minutes.
