Umbral Incantor Evolution for Shadowblade

Adds a new evolution for Shadowblades, the Umbral Incantor.

As an Umbral Incantor, the Shadowblade will regenerate 1 mana per turn and gain several bonuses to their talents if they are equipped with a staff:

- Shadow Combat: the damage will also be triggered when you cast Channel Staff, and when triggered this way can be a spell critical
- Shadowstep: teleport back to starting location after the attack
- lluminate: will use Shadow Dance without cost or triggering cooldown
- Invisibility: will be cast instantly without cost when Stealth is deactivated (still triggers cooldown)
- Shadow Grasp: will pin for 3 turns instead of pulling
- Shadow Veil: rather than blink and attack, you will cast Shadow Grasp on targets selected (without cost and ignoring cooldown and failure chances)
- Lethality: staffs gain a Dexterity damage modifier equal to twice the crit bonus
- Expose Weakness: (if not on cooldown) will be used instantly when casting Shadowstep (before the return teleport), using stamina as usual and going on cooldown for twice the usual duration
- Blade Flurry: (while sustained) also gain spell cooldown reduction equal to the attack speed bonus and an equal chance on spell hit to cast Channel Staff
- Snap: also affect an equal number of spells ("spell/" category talents)
