To clear Hardcore Sortie at 30/30 difficulty in Chaos Zero Nightmare using Tiphera and Rossweisse, use Tiphera’s card draw and shielding abilities early in every turn to fuel Rossweisse’s high-cost burst attacks. This pairing solves the resource starvation and punishing enemy damage scaling of max-modifier runs by guaranteeing consistent card access and reliable barrier coverage.
Core Squad Roles and Deck Building
A successful 30/30 run requires streamlining your combat decks so Tiphera consistently draws Rossweisse’s key finishers without running out of Action Points (AP).
| Combatant | Primary Role | Key Deck Focus | Strategic Priority |
|---|---|---|---|
| Tiphera | Engine Support / Shielder | Low-cost draw, AP recovery, barriers | Cycle the deck and absorb incoming burst damage |
| Rossweisse | Primary Burst Attacker | High-scaling strikes, stance finishers | Maximize burst combos during vulnerability windows |
| Flex Support | Buffer / Debuffer | Vulnerability cards, passive morale generation | Amplify damage output without consuming AP |
Deck Trimming Rules
- Remove basic strikes from Tiphera: Prune non-essential baseline attack cards as early in the run as possible to prevent draw dilution.
- Prioritize Tiphera’s low-cost cycling cards: Upgrade abilities that return AP or draw additional cards on play.
- Keep only high-impact finishers on Rossweisse: Remove intermediate single-target cards that lack stance synergy or high damage scaling.
- Restrict third-slot resource usage: Equip your flex support with passive skills or zero-cost debuffs so all remaining AP goes directly to Rossweisse.
Turn Sequencing and AP Management
At 30/30 difficulty, unspent AP is heavily penalized, while misplaying offensive cards before defensive measures leaves the squad vulnerable to lethal boss retaliation. Follow this activation order across every combat turn:
- Activate Tiphera’s draw and generation skills first: Play Tiphera’s cycling cards at the start of the turn to expand your hand. This reveals your available offensive and defensive options before committing AP.
- Deploy barriers against telegraphed attacks: If an enemy intends to strike on the current turn, activate Tiphera’s shields immediately to secure the party.
- Trigger preparatory buffs and stance shifts: Play zero-cost support debuffs, such as vulnerability, alongside Rossweisse’s setup abilities to build your damage multipliers.
- Unleash Rossweisse’s primary finisher: Spend all remaining AP on Rossweisse’s burst strikes. Cash out damage immediately rather than holding finishers across turns, as high-tier Sortie modifiers can force hand discards or drain AP between rounds.
Handling 30/30 Modifiers and Target Priority
High-tier Sortie modifiers punish slow, defensive attrition by increasing enemy attack values and restricting clear times.
- Multi-target waves: Target high-speed disruptors first. Use Rossweisse’s area-of-effect strikes or directed single-target bursts to take down secondary enemies before they inflict crowd control. Once disruptors are removed, Tiphera can focus shields on the remaining elite.
- Boss phase transitions: Monitor stage boss health thresholds closely. Never trigger a phase change near the end of a turn unless Rossweisse can defeat the boss outright. If your remaining AP is low, spend it on Tiphera’s shields and card replenishment, then initiate the phase transition on the next turn with a fresh AP pool and a full hand.
Tactical Mistakes to Avoid
- Spending AP on damage before establishing shields: Never exhaust your AP pool entirely on Rossweisse while an enemy attack is incoming. High-tier modifiers allow elites to eliminate unsupported characters through unmitigated damage.
- Over-collecting reward cards: Adding excessive cards during run progression dilutes Tiphera’s draw pool. Maintain a lean deck so high-value cycling and finisher cards recur every couple of turns.
- Miscalculating AP breakpoints: Always calculate the total cost of preparatory buffs and finishers before playing your first card. Leaving a high-damage finisher unplayed at the end of a turn wastes valuable hand space and offensive momentum.

Can you add more details about strategy in a future update?
Nice guide. I am checking the other Chaos Zero Nightmare articles next.
I wish I had read this before upgrading the wrong thing.
I tried this today and it worked better than my old setup.
