1. Izuchi (Roland)
A lightning attack that is fired at one target. It's damage level is moderate. Most used spell by Ryner in the prequel. Why Ryner uses it is because it's not too overpowered in damage and it is easier to aim.
2. Kurenai (Roland)
Shoots out multiple balls of fire. AOE spell. It's more powerful than Izuchi in strength. Side effect is that it may set off a fire in the surroundings.
3. Mizumi (Roland)
Fires a large jet of water, pushing against everything in its path. It is the weakest among all attack spells, but has the fastest casting time.
4. Kuuri (Roland)
Fires a fast light ray that explodes on impact. It has long range and is a highly destructive powerful spell that Ryner dislikes using because of the risk of creating casualties.
5. Ante (Roland)
Creates an area of silence for a short period of time. While theoretically, it should stop others from casting spells, but so far, Ryner has only used it to create confusion among the enemy and launch surprise attacks on them.
6. Shira (Roland)
A spell disruption magic. Fires black smoke that erases uninvoked or incomplete magical symbols / inscriptions, preventing the enemy from finishing his spell.
In addition, he also has created his own spells through his own research, as well as possessing spells from Nelpha, Estabul, Runa, and Gastark. I think I may have missed out other stuff here and there though.
