Channel Divinity: Attempts to drive away nearby undead or force them to cower. To turn undead you must make a turning check (roll 1 twenty-sided die + your total Charismamodifier) to determine the Hit Dice of the most powerful undead you can affect. Then you roll 2 six-sided dice + your Cleric level + your Charisma modifier to determine the total Hit Dice of creatures in the area that can turn. Turned undead cower in place or flee. If you have twice as many levels as the undead have Hit Dice, you destroy any that you would normally turn. All Channel Divinity abilities use the same pool of uses per rest.
Turning check: This determines the maximum number of Hit Dice a monster can have and still be affected from your turn undead attempt. If this check does not produce a number equal or higher to the monster near you that has the lowest hit dice, then you will not be able to turn at all and a message pops up saying "You lack conviction to turn the target".
Turning damage: This determines the number of total Hit Dice you will be able to turn. This means that the sum of the affected monsters' hit dice must be less or equal to that number. To determine which monsters you turn, the game starts from the monster with the lowest HD (hit dice) and works its way up. For example: If you can turn 30 total hit dice and you have monsters with (5, 7, 10, 15) HD around you, you will turn the ones with (5, 7, 10) for a total of 22 hit dice and not the (15, 10, 5) that would utilize all 30 of your hit dice.
Before making the checks, your effective turning level is calculated. This consists of:
The sum of your inherent turning levels. Your inherent turning level starts to increase from the level you receive the Turn Undead feat. For clerics, their cleric level is their inherent turning level. For paladins, their level minus 3 is their inherent turning level. A character with both cleric and paladin levels will add their inherent turning levels.
When a monster is affected by your turn attempt, one of the following may happen to it:
Cowering undead: That's the default behavior of turn undead. The monster cowers in place for a period of time. It is not in a helpless state. Once the timer expires, the monster will resume attacking.
Destroying undead: When a monster is affected by your turn attempt, its hit dice are compared to your turning check result. If your turning check result is at least double the monster's hit dice, then the monster is destroyed instead of turned. This effect, in contrast to the cowering effect, is negated by deathblock or deathward. Having the Mighty Turning enhancement means this effect is always applied instead of the cower effect.
Cleric domains may augment Turn Undead to produce more effects. Some of those affecting nearby allies.
There are also items, spells, and enhancements which can help increase your turning ability by boosting your effective cleric level for turning or the number of maximum hit dice you can affect or the number of total hit dice you can turn. These bonuses, according to their type, are added to their respective parts of the turn undead calculations (some in more than one place).
Note: Levels gained in any Epic Destiny of the Divine Sphere do not add to your Effective Cleric Levels for purposes of Turn Undead.
