Blessing of Ailm [Ogham]

The enduring vitality of the evergreen during the darkest of winters is imbued by the spirit of the ailm ogham.

Prerequisite(s): Ogham Connection or the Ogham-Craobh class feature.

Benefit(s): You gain a +1 circumstance bonus to saving throws versus cold including environmental effect. You do not suffer lethal damage when in any cold environment less than severe (-20° Fahrenheit or less), once you are reduced to 0 hit points you just enter a state of hibernation (unconsciousness) until the nonlethal damage is healed.

Even in severe cold conditions, you only suffer nonlethal damage until you are reduced to 0 hit points, after which you suffer lethal damage.

For every ogham feat you possess beyond this one, your circumstance bonus increases by one point (maximum of +5).
