Squishy
Sirius (Sapphire) is a 5 stars Assault character in Artery Gear.
Sirius is a really good single target DPS that scales as well as the gear allows. Due to her speed scaling abilities, she hits harder as she gains both attack and speed. At around 200+ speed and high attack, crit rate and crit damage, she becomes a monster as she can cycle her skills so fast. Her skill sequence would look something like S2 -> S3 -> S1 and repeat. Most units will already die after this combo, unless it is a fire unit, which you will have to open with S3.
However, due to mostly offensive gearing, she is easily taken apart by counter attacks and any form of hard crowd control skills like stuns.
Aside from killing key targets in PvP, she is also very useful in PvE, excelling in Iron Maiden and Harpist. She can also do Centaur, although it is not very effective due to the constant deflects besides from her skill 3.
