A top-tier team defensive and sustain Codex.

Centered around the Four Seasons buff system, it provides massive damage reduction, death immunity, control countermeasures, and team-wide cleansing. It significantly increases team fault tolerance and serves as the ultimate answer to high-burst environments.

I. Codex Skill Breakdown & Star Progression

★0 — Level 2 Damage Cap

Effect 1 — Teamwide Opening Buff

Before the round begins, all allies gain:

• 30% Fixed Damage Reduction
• 30% Final Damage Reduction
• 10% Absolute Damage Reduction

Effect 2 — Autumn Harvest (Level 2 Damage Cap)

At battle start, grant all allies 2 stacks of Autumn Harvest.

Each stack limits a single instance of damage to 20% Max HP.

In the current environment, Green Snake can ignore most traditional damage cap and block effects, making Level 1 caps nearly obsolete. However, Level 2 Damage Cap stacks and works alongside other cap effects to effectively restrain single-target burst — especially Green Snake’s triple Rage and splash piercing damage.

Two stacks of Autumn Harvest can limit:

• 1 Rage hit
• 1 splash instance

This greatly improves anti-burst survivability.

Effect 3 — Stack Consumption

• Max 5 stacks
• Each consumed stack grants the wearer:
  • +20% Damage Taken Reduction (max 100%)
  • Lasts 2 rounds

Tactical Value

1. Perfect anti-burst mechanism — hard counter to high-burst heroes like Green Snake.
2. Even at Default, the 30%/30%/10% layered reductions already significantly enhance team defense.

Recommendation: ★★

★1 — Sustain & Death Immunity

Effect 1

Autumn Harvest increased to 3 stacks (teamwide).

Effect 2 — Unrivaled Force

Refresh Codex activation on rounds 4 / 7 / 10.

Effect 3 — Spring Bloom (Teamwide)

Before each round:
Grant all allies Spring Bloom:

• +30% Recovery Rate (Lv1–2 recovery, excluding Fixed Healing)
• +20% Level 2 revive rate
• Core effect: Immune to first fatal damage and recover 80% Fixed HP

If death immunity is not triggered within 2 rounds, it still restores Fixed HP.

Effect 4

Upon successful revival:

• Consume Spring Bloom
• Gain full 5 stacks of Autumn Harvest

→ Enables 5 layers of damage cap

→ Followed by 100% Damage Taken Reduction window

Tactical Value

The core mechanic Spring Bloom provides a new “first-death immunity” system.

Upon fatal damage:

• Instantly revive with 80% Fixed Healing (Level 3 healing tier)
• Gain 5 stacks of damage cap

Compared to Bai Ze’s revival system:

• Bai Ze: 1★ self / 3★ three allies / 5★ full team
• Agriculture Survey: 1★ already teamwide

Extremely high cost-efficiency.

Recommendation: ★★★★
(Low threshold, extremely high team value)

★3 — On-Hit Cleanse & Counter-Control

Effect 1

Autumn Harvest increased to 4 stacks.
Each consumed stack grants:

• +5% Piercing Damage Reduction (Max 20%)

Effect 2 — Summer (On-Hit Cleanse + Scaling Buff)

When allies consume Autumn Harvest:

• 40% chance to gain 1 stack of Summer
• 30% chance to remove 1 control effect (Once per round)

Each Summer stack:

• +10% Damage Result
• +5% Piercing Damage (Max 3 stacks → 30% result + 15% piercing)

Effect 3 — On-Hit Counter-Control

When allies are hit by Rage or Basic Attack:

• Based on Summer stacks:
  • 20–35% chance to inflict Deep Sleep

Deep Sleep:

• Hard control
• Attack automatically fails
• Removed early if damage exceeds 30% Max HP

Each ally may trigger Deep Sleep once per round.

Tactical Value

1. On-hit Cleanse Multiple hits guarantee at least one cleanse (including Cage, Thunder Trap, Concussion II, Deep Sleep).
2. On-hit Counter-Control Multi-hit attackers (Green Snake, Mo Ye, Ling, etc.) may suddenly “fall asleep” mid-combo.

Important:

Lyvia’s Thunder Punishment is not considered a standard attack sequence, so it does not trigger this mechanic.

Recommendation: ★★★★
(High strength, but higher investment cost than 1★)

★5 — Complete Form & Four Seasons Cycle

Effect 1

Autumn Harvest starts at full 5 stacks (teamwide).

Each consumed stack grants:

• +8% Piercing Damage Reduction (Max 40%)

Effect 2 — Winter Store

When consuming Autumn Harvest:

• 20% chance to gain Winter Store
• Immune to 1 control application
• Once per round

Effect 3 — Core Mechanic: Harvest Blessing

Triggered when team collectively gathers:

• Spring Bloom
• Summer
• Autumn Harvest
• Winter Store (Full Four Seasons)

Activation condition:

After any unit finishes acting → immediately trigger Harvest Blessing.

Effect:

• Cleanse all allies’ HP reduction effects + 1 control
• Restore 80% of lost HP (Fixed Healing)
• 30% chance to inflict Deep Sleep on all enemies

Tactical Value

1. 40% Piercing Damage Reduction + Level 2 control immunity ensures team action reliability.
2. Harvest Blessing is a strategic emergency reset:
   1. Cleanse
   2. Massive recovery
   3. AoE counter-control

Four Seasons are collected across the entire team, not one unit alone — so difficulty is manageable.

Once triggered:

• Full recovery
• Action reset
• Enemy control disruption
• Immediate counterattack opportunity

Recommendation: ★★★★★
(Ultimate defensive system with counteroffensive power)

II. Five Treasures Classic vs Agriculture Survey

Conclusion

From 0–3★:

Agriculture Survey holds clear advantage.

At 5★:

Both Codex options become comparable.

Agriculture Survey fits the current piercing-damage meta better.

Five Treasures Classic was stronger in older multi-segment damage eras.

After reaching 5★:

Both have long-term viability.

Equipping two 3★+ Codexes simultaneously provides excellent hybrid defense.

Star Upgrade Recommendations

• 1★: ★★★★ Spring Bloom teamwide death immunity — major breakpoint.
• 3★: ★★★★ Valuable on-hit cleanse + counter-control + piercing mitigation.
• 5★: ★★★★★ Perfect Four Seasons system with powerful, stable comeback potential.

Final Summary

Agriculture Survey provides:

• Teamwide Level 2 Damage Cap
• Death immunity & Fixed Healing revival
• On-hit cleanse
• On-hit counter-control (Deep Sleep)
• Massive piercing reduction
• Strategic Four Seasons reset mechanic

It is a meta-aligned defensive Codex built for today’s piercing-heavy burst environment.

At 1★ — major power spike.

At 3★ — strong control & anti-burst utility.

At 5★ — full strategic dominance.
