• Effect: Apply 2 Overload. Reaction — trigger when an enemy is killed

A-tier kill-chain Overload spreader — strong in Overload builds, B-tier without them. Zula has Counter 0 (Reaction) and 0 Attack. She never fires on her own counter; she fires when any enemy is killed. On that trigger, she applies 2 Overload to the next enemy. That enemy's Overload detonates when their counter reaches 0 — if the detonation kills them, Zula fires again, chaining to the next target. In wave fights with multiple low-HP enemies, one kill from your main attacker can cascade into a full-wave wipe.

The ceiling depends on Overload detonation actually killing enemies. Overload 2 detonation = 2 damage. For the chain to propagate, enemies need to already be at or below 2 HP when detonation fires. Shen's escalating Overload stacks (4–6 per activation after hits) push detonation damage high enough to kill mid-HP enemies outright, fueling Zula's chain. Without Overload pre-applied at meaningful stacks, Zula's 2 Overload on each kill provides utility but not chain clears.

Boss fights: single-target, no kill chain possible. Zula applies Overload 2 to the boss — accumulates over time — but contributes only as a secondary source, not a chain engine. Her value drops significantly in boss phases.

Back row for Zula — 0 Attack means she contributes nothing from direct combat. HP 7 is durable enough to survive in a secondary position. She operates passively: each kill your party generates triggers her Reaction.

The chain requires a reliable first-kill source. Zula's Reaction fires on the kill event, not on Overload detonation alone. Your main attacker (Dregg, Groff, or another damage carry) needs to land the first kill, then Zula's Overload → detonation → Zula → chain extends from there.

Reduce enemy HP across the wave before attempting the chain. Use area damage or Overload detonations (Shen-applied stacks) to push multiple enemies toward low HP simultaneously. When the first kill triggers Zula's Overload on enemy 2, enemy 2 is already close to death — the 2 Overload detonation finishes them. Then Zula fires on enemy 2's death, applying Overload to enemy 3.

Shen front row + Zula back row is the core combination. Shen applies escalating Overload (2 base, +1 per hit received) per Counter 4 activation, enemies die from detonation when counter reaches 0, each death triggers Zula, Zula applies more Overload to the next enemy. The Shen → Zula pipeline runs automatically with both on the field.

Vesta + Zula double-Overload chain. Vesta doubles current Overload on all enemies in her row (Barrage). Zula applies 2 Overload on each kill; Vesta activating doubles those 2 stacks to 4 before detonation. Overload 4 detonation kills more enemies outright, which triggers more Zula chains. Shen + Vesta + Zula: Shen applies Overload 4–6, Vesta doubles to 8–12, detonation clears the enemy, Zula fires on the kill and applies 2 more Overload to the next target (Vesta doubles that too).

Multi-kill simultaneous triggers. When your attacker kills two enemies at the same time (Barrage, area attack), Zula's Reaction fires for each kill separately. Two simultaneous kills = Zula applies 2 Overload to two different enemies. Both enemies accumulate Overload heading toward detonation simultaneously, expanding the chain width.

HP equalization before chain initiation. Use Shen's Overload application to bring multiple enemies to the same HP threshold before the first kill. When all enemies are sitting at 3–4 HP and Overload has detonated one of them, the chain propagates through the entire wave in one fight sequence. Planning the Overload-equalization phase before the kill-chain phase is the mark of an advanced Shen/Zula pilot.

• Shen — primary Overload applicator; Shen's escalating Overload kills enemies via detonation, each kill triggers Zula's chain; the foundational combo
• Vesta — doubles Overload stacks before detonation; Zula's 2 Overload becomes 4; chain detonation damage floor doubles
• High-damage carries (Dregg, Groff) — Zula needs a reliable first-kill trigger; strong carries land kills consistently; each kill activates Zula
• HP-up charms on Zula — Zula must survive in the back row to keep chaining; HP 7 is durable but extra HP against AoE threats is valuable
• Area damage items/companions — pre-damaging the entire enemy wave toward low HP sets up the Zula chain kill cascade
