Here are some new invocations.
Echoes of the Fallen
Greater; 5th
You call upon the spirits of the fallen to aid you in combat. You can invoke the effects of the summon undead V spell (Spell Compendium, page 217), summoning one or more undead creatures to serve you for up to 1 round per caster level. You can only have one instance of this invocation active at a time. If you invoke this invocation again while the spell is still active, the currently active summon undead V spell is discharged.
Siphon Vitality
Lesser; 3rd
As a ranged touch attack, you can drain the life force of a living creature to heal yourself or an ally within 30 feet. If the attack is successful, the target must make a Fortitude save (DC 10 + 1/2 your caster level + your Charisma modifier) or lose 1d4 points of Constitution. You or an ally within 30 feet of you heal hit points equal to 1d4 times the number of Constitution points drained. You can only use this invocation on any one creature once per hour. Creatures immune to ability drain are immune to this invocation.
Sorcerer King’s Censure
Greater; 5th
You pronounce a powerful curse in the name of your Sorcerer King. As a standard action, you can target a single creature within 60 feet. The target must succeed on a Will save or be afflicted by the curse. Choose one of the following effects:
The target takes a -6 penalty to an ability score (minimum 1).
The target takes a -4 penalty on attack rolls, saving throws, ability checks, and skill checks.
Each turn, the target has a 50% chance to act normally; otherwise, it takes no action.
The curse lasts for 1 minute per caster level. A remove curse, break enchantment, limited wish, miracle, or wish spell can end the curse prematurely.
