Skill Connect

Skill Connect (スキルコネクト, Sukiru Konekuto) is the most widely used OuSS, although it has some annoyingly tight prerequisites.

Overview
Normally, a sword skill inflicts upon a user a post-motion delay that freezes their movement in proportion to the damage caused when using the skill. Skill Connect changes this. It became easier to use after the server-wide glitch on the 75th floor as Cardinal instituted a "flash" to indicate when Skill Connect may be used. Skill Connect takes advantage of a small window in time between the end of a skill and the beginning of the post-motion delay. By unleashing a second sword skill in succession, usually with a second weapon, the user can bypass this delay, normally up to four times. After the introduction of the Hollow Area and the Element Implementation Research, it was possible to utilize Skill Connect way past the normal limit, however, only after completing the research necessary to complete the Implementation of Sword Skill Chains.
