Spiral Tower of Screams guide

Last reviewed · Editor: btiger · Public-source guide.

Spiral Tower of Screams is the tower mode identified by the public guide checked here. Build for consecutive battles with healing and sustained damage rather than assuming every mode is a timed burst test. No separate CZN mode called Clockwork Tower was verified.

Published tower rules: single-source details

Game8's dedicated tower article is the only detailed tower source used in this audit. It lists 150 floors, a Captain Level 45 unlock in Simulation, no turn limit, and groups of five battles with a boss. These remain attributed to that guide, not described as independently re-tested current rules.

Rule in the guidePractical implication
Enemies have every attribute weaknessChoose for synergy and damage pattern rather than one elemental matchup
Defense-based damage receives a bonusDefense-scaling damage dealers can fit the rule set
A per-turn generated-card limit appliesDo not assume unlimited generated-card loops
Consecutive normal/boss encountersRecovery matters across the sequence

How to choose a tower team

Game8 recommends a strong damage core plus recovery, and discusses defense-based options such as Narja, Khalipe and Amir. These are source recommendations, not a universal best team. Editorial approach: retain a reliable heal/shield option, match the team to the listed distortion, and avoid a loop that depends on producing more cards than the mode permits.

  • If the team dies between waves, prioritize recovery and mitigation before adding another damage-only slot.
  • If health is stable but bosses stall, inspect damage scaling, AP and draw consistency.
  • If a generated-card loop stops, check the mode rule rather than assuming the imported preset is broken.

Challenge-floor progress

The same guide describes floors above 100 as a challenge sequence with a team restriction and progress reset when returning to change the team. This is single-source; plan the lineup before a long attempt rather than relying on a documented free swap at every floor.

Is the 8th Basin the same tower?

No. The September 30 update notice describes 1st through 8th Basin under Basin of Hyperspace, a separately named Simulation mode. That particular September 30 to October 21 rotation has ended by this audit date; its modifiers are not copied as current tower rules. The notice was read through CZN.gg and is a single underlying official source.

Clockwork Tower search

No CZN Clockwork Tower entry was verified in the sources checked. This page therefore gives no invented unlock level, rewards or release date for it.
