To open the Cursed Demo Rift in Dragon Soul, the usual requirement is to equip Rage form and have Hope Soul bound to your character; when the rift appears, interact with it first to trigger the cursed version.

What players are saying

A recent guide says the cursed rift opens when you have Rage equipped and Hope Soul bound , then press E on the rift first.

Another tutorial says the same basic setup works for the cursed destroyed future rift: SSJ Rage form equipped , Hope Soul equipped/charged , and being the first one to interact with the rift.

A Reddit post also points to the same general target, asking how to open the Cursed version of the rift in City.

Practical steps

  1. Equip Rage.
  2. Bind or equip Hope Soul.
  3. Wait for the rift to spawn.
  4. Be the first player to interact with it.
  5. Press the interaction key when prompted, usually E.

Extra note

Some players mention that this is easiest in a private server , so random players do not interfere and accidentally trigger the normal version or rush the boss.

If you meant a different rift variant by “Demo Rift,” the requirement is still likely centered on Hope Soul + Rage and first interaction.

TL;DR

Use Rage form , bind Hope Soul , then be first to open the rift ; that should convert it into the cursed version.
