Heretic Surge

Description
This type of Soul Burst is unique in the sense that it doesn't focus soul energy into a single attack. Heretic Surge channels soul energy around the body, changing the user's physical structure to allow them to perform better in different combat situations. These altered forms are called BattlePulses

Each BattlePulse granted by Heretic Surge is named, and boosts/reduces different physical aspects of the user while also granting them special abilities.

BloodRender
A vampiric type. All damage inflicted by the user of BloodRender restores a small amount of the user's lifeforce. The user's Agility is increased while reducing their physical strength. If any techniques other than the ones granted by BloodRender are used while it is active, they drain the user's life force proportionally to the strength of the technique.

Berserker
As the name would indicate, causes the user to become much stronger but at the cost of reducing their reaction time which in turn causes them to move slower. A notable ability the user has while under the effects of Berserker is that their strength increases further the more they are damaged. So if the user were on their last legs they would be a force to be reckoned with. Any techniques used under this BattlePulse are imbued with the element of Earth, increasing their destructive power.

Titan Slayer
Only accessable to those of Yra lineage, or those with knowledge of manipulating Aether. This BattlePulse grants the user immense destructive power and speed at the cost of severe recoil damage when this form cancels itself out after a short period of time. Recoil effects range from extreme fatigue to paralysis. Overuse of this form has been known to kill its users.

Other BattlePulses
Heretic Surge has other BattlePulses but nothing is documented on them, yet...
