Right, as nobody is posting on 'Create A Class' and previous efforts have been way overpowered, here is my idea for a Cosmological build.
Cosmological Class
Use powerful ranged attacks or disappear into the shadows and crush enimies with long term debuffs with this class. You will have low health and no healing abilities, but speed boosts and blocks are their to help you out.
There are two main builds: Shadow, focusing on Speed and DoT, or (duh) Cosmic, which you can use to execute powerful combos. Good things about Shadow: high speed, lots of buffs to choose from. Good things about Cosmic: High damage, blocking attacks. Cons of Shadow: Mediocre health and almost no real ways of dispelling focus. Cons of Cosmic: Very low health, all defences start at 75, no stun moves. Sample Moves
Star Cutter Attack the enemy for 150% of your speed and regenerate 60 focus over 5 turns. CD:0 Costs nothing
Gravity Vortex
Diverts all direct damage to the target, while decreasing all damage done to them by 40%. Costs 50 focus. CD: 5
EM Bolt
Damages the target for 160/170/180/190/200/210/220% of your Instinct and drains 10/11/12/13/14/15/16/17/18 focus from the target. Costs 30/20 focus CD: 1
Shadow State
Increases your direct and periodic damage by 20/25% and your speed by 40% for four turns. CD: 6 Costs 35 focus
More moves including focus dispells and Passive effects coming soon.
P.S Gravity Vortex lasts for 3 turns. It does not affect allie's targets but it does affect DoT. For example:
Partner X uses Infect on Enemy A Sonny uses Gravity Vortex on Enemy B Partner Y uses Leading Strike on Enemy A, but the damage is done to Enemy B. Enemy A uses Leading Strike on Sonny Enemy B uses Destroy on Sonny, and takes the damage for Infect.
Attack the enemy for 130% of your cosmic piercing, 170% of your instinct, and 110% of your speed and apply the effect 'Paralyze' which stuns the enemy for 2 turns.
Attack the enemy for 250/275/300% of your instinct, 25/35/45% of your strength, and 50% of your Light/Dark piercing. Apply the Yin-Yang effect which stuns them for 2/3/4 turns but decreases their damage taken by 30/32/34%.
