This is a guide on how to progress in the early stages of Hero Wars Mobile. It includes efficient ways to play the game and recommended characters for early game progression.
Early Game Progression
No Need to Reroll
Rerolling is not recommended as it takes a very long time.It's better to start the game quickly than to spend time rerolling, as you'll become stronger faster.
Advance the Campaign

Once the tutorial is finished, start by advancing the campaign. Advancing the campaign allows you to obtain new characters and equipment items necessary for development. Also, since the equipment you can get varies by stage, try to advance through the stages as much as possible.
Develop Your Characters
If you can no longer win in the campaign, develop your characters. There are several ways to strengthen characters, but in the early game, it's recommended to focus on 'leveling up skills' and 'promoting characters'.
How to Level Up Skills

Character skill levels are raised using 'Skill Points'. It's recommended to focus on leveling up the skills of tanks and attackers. Also, since Skill Points recover at a rate of 1 point every 5 minutes, it's important to level up skills frequently.
How to Promote Characters

Each character's stats increase when they equip items. Also, equipping 6 items allows them to be 'promoted'. Promotion not only increases stats but also allows them to learn new skills. Equipment can be obtained through the campaign and other means.
Advance Missions

In the early game, you can take on limited-time missions. By completing missions, you can obtain items and other rewards, allowing you to progress efficiently. Also, details about each content and the required level to challenge them are listed, so it's recommended to check the missions as you progress.
Increase Your Team Level
In the early game, focus on increasing your team level. Team level can be raised with experience points earned from campaigns and missions. When 'Guilds' and 'Sanctuary' are unlocked, character development efficiency greatly increases. Therefore, first aim to reach level 30, when Guilds are unlocked, as you progress through the game.
Challenge the City Gate

The City Gate is a mini-game where you defeat enemies with lower numbers than yourself to advance. Clearing it rewards you with gold and experience potions. Stages are unlocked based on the total power of your characters.
Daily Content to Do
Arena

Arena is content where you battle against other players' defense teams. It unlocks when your team level reaches 10. Winning battles earns you Arena Coins. Arena Coins can be exchanged for Soul Stones, equipment items, and more at the 'Merchant'.
Tower

The Tower is content where you aim for the 50th floor while obtaining items and strengthening characters. It unlocks when your team level reaches 15. The items obtainable from treasure chests are luxurious, so be sure to challenge it daily. Also, Tower Coins obtained along the way can be exchanged for items at the 'Merchant'.
Outland

Outland is content where you can earn rewards by defeating 'Highwaymen' and 'Masters'. It unlocks when your team level reaches 25. You can obtain Skin Stones used to enhance and unlock character skins. Also, Outland Coins obtained in Outland can be exchanged for items at the 'Merchant'.
Recommended Characters for Early Game
Astaroth

Astaroth is a tank character obtained during the tutorial. He specializes in protecting allies and serves as a versatile shield. He remains useful even in the mid to late game, so prioritize his development.
Thea

Thea is a healer character obtained during the tutorial. She specializes in healing and recovers allies with her skills. However, her healing amount is less compared to other healer characters, so replace her with another healer once you obtain one.
Morrigan

Morrigan is a support character obtained during the tutorial. Many of Morrigan's skills enhance only 'Path of Eternity' characters. If you plan to build a party centered around Path of Eternity characters, it's worth developing her.
Galahad

Galahad is a tank character obtained at the start of the game. He can deal damage to all enemies with his skills, making him useful as an attacker in the early game. However, he becomes less effective from the mid-game onwards, so his development priority is low.
