Bug Report: Incorrect Spirit Calculation in Demon Form (Aura Activation Issue)

Description:
There is a bug in Demon Form that causes incorrect Spirit reservation when activating auras. This bug severely limits build potential and causes confusion during gameplay.

Issue Details:

When activating an aura, the system displays that it reserves twice the actual Spirit cost.

The skill tooltip shows the correct reservation amount, but the system incorrectly reduces the available Spirit pool.

This mismatch prevents players from activating additional auras, even though sufficient Spirit remains based on the actual reservation costs.

Example Scenario:

You have 147 Spirit.

You try to activate “Cast on Freeze” aura.

The system shows it will reserve 120 Spirit, leaving only 27 Spirit.

However, the tooltip shows that it actually reserves only 60 Spirit, meaning 87 Spirit should remain.

Despite this, the system does not allow activating further auras as if 120 Spirit were reserved.

Impact:
This bug breaks aura-heavy builds and causes frustration for players trying to optimize their Spirit usage. It creates a misleading experience and forces players into unnecessary workarounds.

Suggested Fix:
Please review how Spirit reservation is being calculated in Demon Form, especially during aura activation. Ensure the UI and actual reservation values are synchronized correctly.
