how should i empower my soul to increase willpower-based abilities' efficiency?
The Solar Chakra is the source of 'The Will' in the power of our souls to manifest our desires.
It is the powerhouse of our soul and having a strong Solar Chakra assists in matters of clarity in control through rulerships of the Sun such as confidence and self-expression, vitality, raising self-esteem, your will, your overall power, all of which help greatly in directing energy and, as you say, "willpower-based abilities".
All chakras are important though, the absolute most best results you'll ever get is when
all of your chakras are equally empowered, equally cleaned, strengthened and balanced with each other including your elements.
Harmony is what burns through chaos and disorder with clarity so strong it is a force to be reckoned with. Everything balanced, creativity and imagination, discipline and control. Keep that in mind as you develop at your own pace.
