Original Sword Skill

The «**Original Sword Skill**» (オリジナル・ソードスキル, *Orijinaru Sōdo Sukiru*?) system, implemented in «ALfheim Online» and abbreviated as **OSS**, is a game mechanic that allows for a player to create a «Sword Skill» of their own, unique to them, the creator. The system is left largely unchanged when «ALfheim Online» was refurbished into «Spell Blade Online»

## Mechanics

The reason why the «Original Sword Skill» system exists is that in the world of ALO, «Sword Skills» actually do not exist. This system was implemented as a way for high-level players to create their own unique attacks unmanaged by the system. However, in order to use the system, the player needs to first and foremost possess a required skill level proficiency in their weapon skill before even attempting to create an OSS as the system is blocked by a level barrier. Once the system is unlocked, the player only needs to open up the menu, move to the OSS panel and activate the «Sword Skill Recording Mode» by pressing "Start". Once this is done, the player can now swing their weapon in any desired set of movements before pressing «Finish» once completed.

The most problematic downside of this system is that such movement sets that the player is doing in order to create the OSS are only accepted by the system if they meet three hurdles: it must be precisely executed at a high speed while also meeting perfect combo requirements. To elaborate, in order to create an OSS, the player must be able to execute the skill flawlessly, at the same speed as the completed skill but entirely unassisted by the system. (Normally, this would be impossible without the assistance of the system but there are multiple players that have managed to create them.)

Besides adding the ability to automatically use the newly invented moves, it also allows the creating player the option of adding elemental damage, which can range from fire-elemental, earth-elemental, lightning-elemental, water-elemental, light-elemental, and dark-elemental, or any two elements to the OSS. This means that on top of the physical damage normally dealt, the OSS also deals either one or two types of elemental magical damage, creating a percentage dividing magical damage and physical damage.

### Legacy

A so-called «Skill Manual» can be created to hand over a player's created OSS to other players, resulting in an extra way for high-level players to create some income by selling their OSS's.*[citation needed]* OSS's with a total hit count of 5 or more are the most expensive due to being extremely difficult to create.*[citation needed]* The one downside of this is that each player can only give one «Skill Manual» of each OSS to another player, essentially meaning that it can only be given to one other player.*[citation needed]*
