The Sin of Envy is a Deadly Sin boss on Envy's Coliseum. The floor is guaranteed once between Floor 20 and 24. If a Malfunction is also queued, Envy takes the floor. Speed is 20–30, sight is 60, and the Terminal lists MDL 185%. Foxxive has called Envy the weakest Deadly Sin. That does not make the floor optional.
What the floor changes
You destroy 10 plants instead of normal tasks. On entry, vines snare your items. Each plant you destroy returns items at random. Since the Recode, clicking a plant puts vines on the screen that you cut with scissors. The older, slower generator-style check is the pre-recode plant.
Envy roams the whole arena. Walls and pits break line of sight, and they also hide Envy. Invisibility lets you pass through Envy, but movement noise still gets a short reaction. Contact is an instant kill.
The spear is the ranged threat. A hit does 50 damage, knockback, and a stun. Death notes on the entity page say a dagger hit, the older weapon, was usually the end of the chase. The spear is the current weapon. Do not stand in the open to finish a plant.
Leeching Roses
Roses appear over time and get denser. Stepping on one snares you. You click the vines to break out. The damage number on the rose is not published on the current page. Envy runs toward activated roses and toward finished plants, so a snare in line of sight is the usual death. After you clear the floor, Leeching Roses can spawn as normal traps and use the same breakout.
Rewards
Clearing the floor grants information on Envy and on the coliseum immediately. Completing the Terminal entry awards the Rose of Envy starter. The Kindness badge is for finishing the encounter. The Unholy badge is for meeting any Deadly Sin, including Envy.
Sloth is a different failure
The Sin of Sloth is not this floor. The current guide says Sloth can appear when Delvers are not completing tasks regularly through the expedition. It is a separate Deadly Sin. This page does not repeat older time-trial steps, because the current guide does not restate them.
