🔥 AoE Is King & Synergy Wins Runs
Onslaught isn’t a solo sprint; it’s a marathon of destruction. AoE damage is non-negotiable. Bring Descendants like Valby or Freyna who can melt groups instantly. Crowd control is your best friend—slow, stun, and poison effects buy precious seconds when the screen fills up. Don’t ignore support! A buffer or shielder like Ajax can keep the team alive during brutal spikes. Synergy beats raw DPS every time; coordinate your skill rotations to maintain constant pressure without downtime.

Positioning saves runs. Stick to choke points where enemies funnel in, making your AoE skills devastatingly efficient. Watch the minimap for Elite Spawns and Boss Waves. These require focused fire and ultimate coordination. Save your ultimates for these moments rather than wasting them on trash mobs. Communication is key—call out threats and rotate cooldowns to ensure someone always has a big play ready.
The loot table is stacked. You’re hunting for Rare Modules, Gold, and essential Upgrade Materials that accelerate your build progression. Higher waves yield better drops, so pushing your limit is worth the risk. Even if you wipe, you often keep partial rewards, making every attempt valuable.
