Endure Heat
Core Identity
Heat is about endurance, energy, aggression, and explosive force.

Rank 1 - Base Effects
  • Heat Endurance - For each level with this skill, the temperature is considered 3 degrees cooler for the purpose of determining the ill effects of heat (greater END usage, etc.). For example, if the temperature is 100 degrees, and the character is rank 3 in this talent, they treat the temperature as if it were 91 degrees (100 - (rank x 3)).
  • Fire/Heat Damage Reduction - The character suffers 1 less point of damage per rank from spells such as Fire Bolt and Fireball.


Rank 5 – Heat Acclimation

Minimums:
  • CON 18
  • Ignore all non-magical heat penalties (fatigue, dehydration penalties, END drain increases, etc.).
  • Can operate in extreme heat (deserts, lava-adjacent zones) without checks for extended periods.

Rank 8 – Flame Guard

Minimums:
  • CON 18
  • MA 16
  • +1 per rank on saves vs burning, panic, or heat exhaustion effects.
  • Ongoing fire damage (burning) is reduced by 50% duration or ticks.

Rank 10 – Blazing Resilience

Minimums:
  • CON 19
  • MA 17
  • Fire/Heat Damage Reduction is increased to 2 points per round (instead of 1).
  • If damage is reduced to 0, you gain “Heat Surge”:
    • Choose one: +2 initiative or +10 SC for one round, beginning immediately (i.e., if struck on initiative 8, the bonus will last until initiative 8 of the following round).

Rank 12 – Furnace Core

Minimums:
  • CON 20
  • MA 17
  • Convert heat into stamina:
    • Regain 1 point of END or non-lethal damage per round while in hot environments. If down both, regain NL first and then END.
  • Immune to mundane heat hazards (heatstroke, dehydration penalties, etc.).

Rank 15 – Avatar of Flame (Supernatural)

Minimums:
  • CON 21
  • MA 19
  • Immune to non-magical fire damage.
  • Magical fire/heat damage is halved before reductions and saving throws.
  • Once per encounter, emit a Heat Wave / Flame Burst:
    • Adjacent enemies take 2d6 fire damage and may be staggered or forced back if susceptible to fire.
  • Your body radiates heat. You can ignite small objects with touch or leave scorch marks on surfaces.
