Vivianne ultimate fix
Vivienne's Ultimate Skill's (Giant Destroyer of All Things) skill range is a known issue as the skill tooltip states "skill inflicts damage 4m around the enemy," but the range is greater and the damage is being applied to all enemies.
Also, we have found an additional issue with the Ultimate Skill effect. The skill applies additional damage of 90%, 95%, 100% but unlike what was intended, it was applying 110%, 115%, and 120%.
However, changing both the skill range and additional damage applied could cause inconvenience to the Saviors who are utilizing Vivienne in their party, so we have decided to fix only the skill range by cutting back on the skill range back to 4m as intended, and we will not fix the additional skill damage inflicted.
We the development team are well aware that bringing changes to specs. and skills for Souls can bring a major effect on your gameplay experience.
We apologize for the inconvenience caused due to Vivienne's skill issue above, and we promise constant balance checks to reduce such issues.
Vivienne's Ultimate Skill, "Giant Destroyer of All Things" skill range will be fixed to correctly apply damage 4m around the enemy as the skill tooltip states, and the visual issue of skill effect and the actual hit being inflicted appearing to occur at different spots will be fixed.
Vivienne's Ultimate Skill, "Giant Destroyer of All Things," will have the tooltip changed to additional state damage of 110%, 115%, and 120% (from the previous 90%, 95%, and 100%).
TL;DR Vivienne's Ultimate range will now only hit targets in the frontline, but it will still do the same damage as she does now. So she will go from beyond broken, to merely really strong.
