RodionR Corp. 4th Pack Reindeer
Generate 
Charge Count with her S1 and S2 then spend it on her S3. S2 consumes some but it's always a net gain.
At 5-9 Charge Count, her S3 hits randomly between the main target and another random target (either an ally or enemy). At 3+ Potency, it stops targeting allies, so it will only target enemies. The skill consumes all her Count to gain +2 Coin Power on the first 10 and deal more damage for any excess beyond that.
Standard Charge build up (+1 Potency every 10 Count consumed, Potency increases damage dealt).
Her passive doubles her 
Sinking application against targets without Sinking.
She can gain Sinking from losing clashes, triggering the downside of her S2 or S3 (not enough Charge), or when triggering her passive. She doesn't do anything with it, so it's purely a downside. Be careful of the stack building up especially if she never gets hit because Sinking doesn't decay naturally.
