Notes

Umbra, though similar to Level 4 Darkness in every way known, is a proper level 4 Skillchain.

Deals Dark, Earth, Water, or Ice damage. Damage type is picked by monster's elemental resistances, and in the case of equal resistances it generally follows the pattern of Ice > Earth > Water > Dark.

For a two-step Umbra, the Skillchain damage is roughly twice the final Weapon Skill damage before resistances or bonuses. Skillchain damage of a given element can be enhanced with day/weather bonuses from the Elemental Obis and by Staves. See the main Skillchain page for more information.

Generating Darkness

It can only result from:

Any skillchain -> Any skillchain -> Darkness (Skillchain) -> Darkness (WS property), cannot be "continued" by any other Skillchain property, and can only be made while under the effects of any Level of Aeonic Aftermath.
Any skillchain -> Darkness (Skillchain) -> Darkness (WS property), cannot be "continued" by any other Skillchain property, and can only be made while under the effects of Level 2~3 Aeonic Aftermath.
Darkness (WS property) -> Darkness (WS property), cannot be "continued" by any other Skillchain property, and can only be made while under the effects of Level 3 Aeonic Aftermath.
