Contractually Unbound is a grandmaster combat achievement which requires the player to defeat Yama under the elevated conditions of one of his non-standard contracts.

Strategy

Players may choose to complete this achievement with any one of the following contracts:

The contract of forfeit breath is generally considered the easiest out of the six as maintaining run energy for the fight is not as complex as dealing with the mechanical changes in the other four contracts. The baseline changes for all sigil contracts are as follows:

  • Yama does two standard attacks before a special attack; glyphs respawn faster.
  • Shadow Waves and Fire Streaks appear more frequently.
  • Special attacks in phase 1 land 1 tick earlier than usual.
  • Phase transition thresholds trigger at 75% and 50% health.
  • The Judge of Yama throws fire bombs every 3 ticks, and throws two per attack.
  • Shadow Waves and Shadow Crashes are more frequent in phase 3.

Other tasks

There are 11 Combat Achievement tasks (totalling 55 points) available for Yama.
