Bloody Fissure Thunder Thrust

''“This technique is most useful right at the start of combat. That is, if you use it in the first turn it will unleash its full power. Every turn after that, its power will slowly wane. Choose wisely whether it's worth it to use the SP.”'' - Alice

''“It's said that Bloody Fernandez mastered this technique, and covered the battlefield with her bloody thrusts. Using this Blood Fissure Thunder Thrust technique, she killed her enemies one after another, making a lake of blood.”'' - Alice

Bloody Fissure Thunder Thrust (or simply Thunder Thrust) is a skill taught to Luka by Alice after he sets up camp with her after the Leech Girl’s defeat. Luka omits the “Bloody Fissure” part, leaving only “Thunder Thrust”.

It is a high-speed thrust attack that consumes 2 SP to use and deals significant damage if used on the first turn; however its effectiveness is decreased if used later. It is also the key to defeating certain monsters, such as Page 17.

Thunder Thrust is eventually replaced by Lightning Sword Flash after fighting Scylla, but he is forced to resort to using Thunder Thrust again after defeating Archangel Ariel, as Promestein disables his elements. Thunder Thrust is soon replaced by Flash Kill while fighting Archangel Ranael.
