Combat Skills
Each character can use certain types of specific weapons in Sword Art Online: Lost Song. For instance, Kirito can use Dual Blades, a single One-Handed Sword, or a Two-Handed Sword. Using either of these types will level your skill with them up making them more powerful. It’s best to try and pick one or two types early so you can level them up quickly. Each will start at Skill Level 100, granting you two abilities.
These abilities will only level up if you do damage with them. Since they require mana, you’ll want to only use them on groups of enemies or really powerful enemies. Do not waste them on single weak enemies. Luckily, the open area of each island has tons of grouped up enemies making this much easier than if you were in a dungeon. So jump into the fray and let it rip.
