The Succession version of Ultimate: Dark Flame has the skill description "Increased attack area and damage upon consuming Shards of Darkness x1", however the damage is not increased even though shards are consumed.

This mechanic works for Shadow Eruption which has a similar skill description, however for Succession: Ultimate: Dark Flame the damage is completely uneffected. 

How to reproduce:

Perform the skill with and without shards and compare the damage between the two versions.

Standing further away from the opponent will make it so you avoid regenerating shards from the skill itself, and only compare damage of the "extra attack damage".

Solving this bug is important and relevant for the recent changes on Global Labs where the developers wants us to use this skill more to rely less on damage from Black Wave.

Please fix thanks
