Use your strongest heroes as rally leader, the correct first hero when joining, and a 10/10/80 formation for maximum damage.
→When starting a rally, send your strongest heroes.→When joining a rally, place Jessie, Jasser, Reina, Seo-yoon, Jeronimo, or Philly in the first, far-left hero slot. These heroes provide damage bonuses.→Do not send the same hero if the rally already has several copies of that hero.→If none of these heroes are available, send troops only. Unsuitable heroes will be removed from the rally.→For maximum damage, use a 10/10/80 troop ratio: Infantry / Lancers / Marksmen. Feel free to experiment with other formations as well.→Higher damage means better rewards.
Prepare troops, teleports, and roles in advance, avoid unnecessary battles, and heal without Speedups.
→Keep training the highest-tier troops available to you.→Save Gems and Teleport Scrolls.→Heal troops in 2–3-minute batches; do not use Speedups.→High-Furnace players: assign one squad to reinforce a weaker player so we can support one another.→Prepare separate attack and defense squads.→Avoid unnecessary battles.→If your troops are too badly injured, leave the battle and return after 12 minutes. They will be fully healed.
