Psychic Class Spheres Conversion
Casting: The sphere psychic may combine spheres and talents
to create magical effects. The sphere psychic is considered
a High-Caster and uses Intelligence as his casting ability modifier.
(Note: All casters gain 2 bonus talents and may select a casting
tradition the first time they gain the casting class feature.) Phrenic Amplifications instead apply to sphere effects instead of spells.
This replaces the spells class feature.

Spell Points: The sphere psychic gains a small reservoir of
energy he can call on to create truly wondrous effects, called
a spell pool. This pool contains a number of spell points equal
to his level + his Intelligence modifier (minimum: 1). This pool
replenishes once per day after roughly 8 hours of rest.

Power of the Mind: A sphere psychic gains +1 spell point at 2nd level and every 2 levels thereafter.
This replaces all discipline spells.

Magic Talents: A sphere psychic gains two magic talents at 1st level, one of which must be in the Psychic tradition, and one magic talent every
level thereafter.
