Descending Dark

Use
Press the FOCUS/CAST or QUICK CAST button while holding DOWN to cause the player character to slam into the ground, creating a shockwave that spreads out and up, dealing damage in two bursts.

The player is invincible for a very short period during and after using Descending Dark. This allows for chaining uses of Descending Dark to avoid enemy damage as long as the player has enough SOUL.

How to Acquire
An upgrade to Desolate Dive. Found on a Snail Shaman's corpse in Crystal Peak, within the Crystalised Mound. Requires Crystal Heart to reach.

Be aware that the Crystalised Mound can be difficult to traverse, as it has fairly few foes to gather Soul from and a lot of hazards and relatively tricky platforming. It may be a good idea to acquire the Hiveblood from The Hive before tackling this challenge.

Modifiers

 * Shaman Stone increases the damage dealt by Descending Dark by 33%.
 * Spell Twister lowers the SOUL cost to cast Descending Dark by 33%.
