Chaos Zero Nightmare Anniversary Banner and Reward Guide

To maximize your account gains during the Chaos Zero Nightmare anniversary, immediately halt spending on permanent banners and reserve your premium currency until you can reach the hard guarantee on a featured seasonal combatant. In parallel, redirect your daily stamina into limited celebration stages to clear out exclusive rewards before farming routine upgrade nodes.

Evaluating Seasonal Combatant Banners

Seasonal combatants feature time-limited kits that do not enter the standard summoning pool after their banners expire. Because partial progress on these limited pools risks wasted currency, evaluate banner spending against three specific account requirements:

Kit Uniqueness: Check whether the unit offers card-draw manipulation, distinct debuff removal, or unique damage scaling that standard 5-star alternatives cannot duplicate.
Pity Threshold Safety: Pull only when you hold enough summon currency to trigger the hard guarantee. Committing partial reserves leaves your roster vulnerable if you fail to hit the featured combatant before the banner leaves.
Squad Synergy: Confirm that your roster already contains the compatible supports or secondary damage dealers required to build around the seasonal combatant's deck archetype.

Pass on niche damage dealers that depend on unowned companion units, and prioritize versatile combatants that slot into multiple squad configurations.

Anniversary Currency Allocation

The anniversary celebration distributes summoning tokens, account upgrade bundles, and stamina across several distinct channels. Allocate each asset to its intended use rather than spreading resources thin.

Reward Type	Primary Source	Resource Strategy
Limited Summon Tickets	Milestone logins and stream codes	Bank exclusively for featured seasonal banners; avoid unbudgeted single pulls.
Standard Pull Currency	Celebration mail and stage clears	Spend on standard pools to push toward milestone selectors or combatant unbinds.
Stamina Restorations	Daily login distribution	Stockpile until event bonus drop stages unlock to farm gear and talent materials.
Enhancement Catalysts	Anniversary exchange shop	Direct strictly toward core abilities for your primary damage dealer and main support.

Avoid converting universal currency into standard banner summons while seasonal banners remain active, as this limits your pull flexibility.

Event Stage Progression and Farming Priorities

Celebration stages provide event tokens redeemable for rare character unbind items, high-tier deck upgrade materials, and exclusive memory cards. Use this order of operations to clear the event efficiently:

Clear every story and challenge event stage once to collect initial clear currencies and premium rewards.
Shift all surplus daily stamina to the highest-difficulty event stage your squad can farm reliably.
Redeem event shop stock in order of scarcity: buy limited summon tickets, rare catalysts, and exclusive memory cards first.
Purchase standard gold and basic experience items only after all limited and high-tier account upgrades have been cleared from the shop.

Post-Anniversary Unit Investment

Receiving multiple new combatants during the anniversary can cause severe bottlenecks in talent and leveling items. Concentrate your celebration upgrade chests on one unit at a time, beginning with your newly acquired seasonal combatant. Maximize their primary skill cards and core abilities before evaluating how their inclusion alters your squad rotations in high-difficulty encounters. Once that unit reaches combat readiness, move remaining materials to secondary supports.
