Luck
Luck is a powerful trait that gives units a 75% chance to evade any damage from external sources that would otherwise kill them.
Luck is largely an Astral buff, given by:
The
Personal Luck spell, which requires
1 and only
Alteration 1 but only affects the caster,
The
Luck spell, which requires
1 and Alteration 3, affecting one tile of friendly units,
The
Battle Fortune spell, which requires
3 and Alteration 6, affecting 5 tiles of friendly units for
1
,
The
Will of the Fates spell, which requires
4 and Alteration 8, affecting all friendly units for
4
,
Several
Magic Items, which only your Commanders can use,
And the Luck
Blessing, which requires
9 Bless points and
2 on your Dominion
scales, and which effects all of your Blessed units while your
Pretender is awake and alive.
Undead and Inanimates are unaffected by luck. In addition, a unit with
Cursed Luck temporarily does not benefit from Luck. This effect can be caused by the
Fateweaving Bless, Luck's counterpart.
Luck is amazing to have on chaff (small frontline troops who you don't count on living) and is a decent layer of protection for your weaker Commanders against ranged attacks. You shouldn't press your Luck too hard, though.
