List: Warlock Defenses

Backdraft

Element: Voidflame

Your flames both protect and consume you, inside and out. When a creature hits you with a melee attack, the attacker takes 1 point of fire damage for every four warlock levels you possess.

This bonus can be increased for 1 minute at the cost of eldritch energy. For each point you spend, backdraft applies its damage an additional time. The total damage done by backdraft cannot exceed +200% (Spending 2 points of energy to apply damage two additional times.)

Eldritch Resilience

Element: General

You tap into the knowledge of the Void to grant yourself fast healing 1. At 8th level and every 5 warlock levels thereafter, the fast healing increases by 1. Eldritch resistance has a duration of 2 minutes.

Unlike other defenses, eldritch resilience uses a full-round action to activate. You can spend 2 points of eldritch energy to activate eldritch resilience as an immediate action.

Entropic Skin

Element: General

The chaotic nature of the void alters your skin, the swirling chaotic energies causing blows to miss their mark. You gain a +1 enhancement bonus to your existing natural armor, increasing by +1 for every five warlock levels you possess beyond the 2nd.

This bonus can be increased at the cost of eldritch energy. For each point you spend, entropic skin grants an additional +1 bonus. Bonuses gained in this way cannot exceed 50% of its starting value, and have a duration of 2 minutes.

Frost Shield

Element: Rime

Calling on the frigid emptiness, you create a floating ward of ice that protects you from harm. Ice shield grants a +2 shield bonus to AC, increasing by +1 for every 4 warlock levels you possess beyond the 2nd.

This bonus can be increased at the cost of eldritch energy. For each point you spend, frost shield grants an additional +1 bonus. Bonuses gained in this way cannot exceed 50% of its starting value, and have a duration of 2 minutes. 

Emptiness

Element: Gloom

Your body becomes an empty husk, fueled by an internal void. You gain the following:

Every four warlock levels you posses beyond the second, the bonuses above are increased by the amount in brackets.

Warding Light

Element: Voidshine

You surround yourself with a visible ward, granting you a number of temporary hit points equal to your warlock level. These temporary hit points can put you over your maximum hit points, and regenerate at a rate of 1 per minute. 

You can increase the regeneration rate of this ward for 2 minutes at the cost of eldritch energy. For each point you spend, the rate increases by 1.
