Beast Pet Arrival is a synthesis tower defense strategy mobile game, where players not only need to cultivate characters but also need to reasonably build a lineup to advance through levels. So, what are the recommended lineup combinations for Beast Pet Arrival? Currently, there are four major systems in this game, each corresponding to different attributes and mechanisms, and each system has unique core output, support, and control units. Grouping heroes of the same system can trigger additional attribute bonuses, so during the early stages, it's best to focus resources on building a complete lineup around one system.

Preface:
During the server opening phase, the system gives away several core heroes, such as the Six-Eared Macaque obtained by logging in, Hong Hai'er and Black Bear Spirit from the opening gift packs, and rare heroes like Little Yellow Dragon, Ling Xi Longnv, Kang Jin Xingjun, and Princess Wansheng, which are easily obtainable through regular draws. Although these are not the highest rarity, they have low acquisition thresholds and fast star-upgrading speeds, allowing for the quick formation of a powerful team under limited initial resources. Additionally, rare heroes may trigger a same-hero feedback mechanism during the synthesis process, further accelerating the 5-star advancement speed. Therefore, it's advised to avoid dispersing resources during the early stages, treating extra heroes as fodder, and focusing on developing 2-3 high-star main cores.

Card Pool Rotation:
The general draw pool and the limited-time draw pool, with the latter being key to building the core lineup. Each limited-time draw pool focuses on a specific attribute system, rotating in cycles: Great Sage Returns (Physical), Nezha Reborn (Fire), True Lord Manifests (Thunder), and Destiny's Strange Fate (Water). You can set your desired hero, increasing the probability of drawing specific rare or rare+ heroes.

Physical System:
Among the physical system, the Great Sage Returns card pool is the most suitable for direct investment at the start of the server. The core outputs are Sun Wukong and Patriarch Bodhi, featuring very strong mechanisms such as crit, armor penetration, and stun, capable of dealing highly suppressive group damage. Especially in map-clearing and resource missions, the cycle of crit and control can bring surprisingly efficient map clearance. Surrounding heroes like the Six-Eared Macaque and the Arm-Stretching Ape, form a secondary system centered around General White Eyebrow, enhancing overall survival and control chains. However, this system consumes a lot of resources; if unable to quickly upgrade stars, mid-game combat power will be mediocre. It's suggested that common players prioritize upgrading Sun Wukong to purple 4-stars after obtaining him, then gradually complete the core positions through return events or self-selection activities.

Fire System
Nezha Reborn is the second limited-time draw pool, suitable for players who have accumulated some resources in the early stage. The core of the system is the Crimson Flame Demon Child, with multi-stage burst and burn vulnerability mechanisms, offering superior sustained output compared to the physical system, making it suitable for PVE and boss battles. If resources are limited and you couldn't draw Sun Wukong in the first round, then the Nezha Reborn card pool is a more stable choice. Venerable Luo Jia is also an important support option, capable of inflicting burn status on enemies and providing some control effects, helping the Crimson Flame Demon Child deal massive damage. The fire system leans towards sustained output rather than control, so when building the lineup, you can select some heroes from other systems to complement, such as pairing with water system's freeze or thunder system's paralysis to improve fault tolerance.

Thunder System
"True Lord Manifests" is the system with the strongest burst, represented by the core Erlang Shen, possessing high true damage and powerful single-target suppression, capable of quickly eliminating enemy main forces. In the mid to late game, or against elite bosses, the single-target breakthrough capability of the thunder system far exceeds that of other systems, especially when paired with Thunder Envoys (such as Little Yellow Dragon, Kang Jin Xingjun), combining AOE and paralysis control, performing well in various scenarios. If you didn't invest in the first two limited-time pools, then it's time to go for "True Lord Manifests."

Water System
Destiny's Strange Fate is the most versatile and efficient to develop among the four systems. The core Ao Guang and Ao Run not only possess strong control abilities like freezing and slowing, but can also be used as synthesis materials for each other, greatly reducing the risk of getting stuck in development. This system, with its frequent AOE output and control capabilities, performs well in map-clearing, grinding, and even PvP. Although its burst is not as high as the Great Sage or Erlang Shen, its overall rhythm is light and its mechanics are complete, making it a very friendly choice for common players. If planning to go for the water system, you can also pair it with auxiliary units like the Oceanic Dragon God or the Azure Wave Demon Saint to enhance sustained output and control.

Recommended lineup combinations for Beast Pet Arrival should be judged based on your own resource investment capacity, hero acquisition, and future card pool planning. Big spenders can prioritize building a versatile team with high burst, high control, and high AOE around multiple rare cores (such as Sun Wukong + Erlang Shen + Oceanic Dragon God). For ordinary players, choosing a stable and star-upgradable system, focusing on developing core positions, and skipping 1-2 rounds of limited-time card pools to accumulate resources, often leads to a longer and more stable growth curve.
