Deep Focus

Description
''Naturally formed within a crystal over a long period. Draws in SOUL from the surrounding air.''

The bearer will focus SOUL at a slower rate, but the healing effect will double.

How to Acquire
Found in Crystal Peak in a hidden cave made entirely of crystals.

Below the area where the player finds Cornifer, look for a Husk Miner mining a wall. Break the wall to reveal the secret area. Requires Crystal Heart.

Usefulness
Its restrictive cost and slow focus time make it hard to use in boss battles, so its main purpose is tackling difficult platforming challenges, where it shines in combination with Grubsong and Hiveblood.
