Repeater Build

In Hell Clock, the Repeater Build is an incredibly powerful and efficient setup, specifically designed for rapidly clearing dungeons in the early stages of the game. Centered around the Repeater ability, this build excels at both high single-target damage and effective area-of-effect (AoE) clearing.


This build primarily leverages the Repeater ability as its main damage source, complementing it with various relic synergies to boost mana efficiency, diversify damage types, and enhance AoE capabilities.


  • Description: This is the primary damage ability for the build, providing a rapid and continuous stream of fire.
  • Focus: It’s effective against both single targets (bosses) and groups of enemies (for clearing rooms).

These specific relics are crucial for maximizing the Repeater Build’s potential:

  • Fire Damage Conversion:

    • Benefit: This changes your ability’s damage type, making you more effective against fire-vulnerable enemies and potentially creating synergies with other fire-focused relics or buffs.
  • Grenade Drop Chance:

    • Benefit: Provides additional AoE damage, helping you clear groups of enemies faster. This is invaluable in crowded rooms.
  • Plague Explosion:

    • Benefit: Significantly boosts Repeater’s AoE capabilities. It creates chain reactions upon enemy kills, dealing additional Plague damage to nearby foes, which is vital for rapid room clearing.
  • Mana Cost Reduction:

    • Benefit: Allows you to use Repeater more frequently and makes mana management much easier. This is critical in sustained fights or high-attack-speed setups.

  • Slow Time:
    • Description: If you can find relics that grant bonus damage to enemies within a “Slow Time” field, this ability can be a fantastic support for your Repeater Build.
    • Synergy: It allows you to slow down enemies while simultaneously increasing the damage they take from your Repeater, enhancing both control and offensive output.

  • Relic Priority: During your runs, prioritize seeking out the key relics mentioned above. The mana cost reduction and plague explosion relics, in particular, form the backbone of this build’s effectiveness.
  • Mana Management: Thanks to mana cost reduction relics, you should experience fewer mana issues, allowing for continuous Repeater usage.
  • Fast Clearing: This build excels at quickly eliminating groups of enemies, enabling faster progression through dungeons.
