"Sure thing! Heimerdinger is a famous inventor from Bandle City, and once he made a pair of special glasses for the renowned Sword Saint. In return, the Sword Saint gave him this Ambush Slash Rune. This rune allows a warrior's charge skills to assault continuously several times, creating afterimages amongst a group of enemies at an incredible pace, and attack multiple enemies in succession," Teemo explained in detail, "But none of us are warriors, so this rune isn't very useful for us. If you can help me improve this blow dart gun, I'll give you this rune stone!"
"Okay, no problem!" Huang Yi nodded. This could be considered a task given by a system NPC, which would reward him with the rune stone upon completion. However, there wasn't usually a strict task process in The Second World, and the presentation could be quite casual. Sometimes a task might arise just from chatting, and it often depended on whether the player felt like delving into it.
