Soul Energy

Soul Energy [SE] (you can call it mind power or psi) is an inner power, the use is similar to Weapon Bond use from Occult Slayer (resembles Depravity use from Tainted Scholar or Ki use from Monk). Rest does not reset it!

Whatever its origin, it is sure to be available in limited quantities. The owner must decide how to allocate its use. It focuses on itself to strengthen itself or to influence the world with it. 

Book of the Mind

The Book of the Mind is not a real book. It's a part of the rogue's mind, in which you store spells memorized from the scrolls. (It is technically easier to treat it as a spell book.)

A rogue's mind can contain a wide variety of spells. You can only memorize a few spells into the Book of Mind (max 9 spell), but you can override them from scrolls while resting.

            • Level 3 slots: 2. level Artificer/Alchemist scroll

Tricks & Basic Concepts 

Memorized spells are much more effective dath an using scrolls:

You cast this "spell" instant (~Quicken) as a rogue level (+Epic/Legendary caster level) caster.

Trick DC (~Heighten) =  10 + half Rogue level + Intelligence modifier + bonuses to Assassinate

Damages: 

• • • Tricks damage scales with 200% Mystical Power,

    • Delayed & Thiefed Magic damage scalles with 100% Mystical Power,

but has no critical chance and multiplier. (Spell Powers/Criticals unaffected!)

Mystical Power = current SE + melee/ranged power
