Robyn

If you don't like guns, maybe you're interested in archery.

Skill comparison
Attack Skill Ultimate skill Passive skill
 * Robyn fires several arrows which chase enemies.
 * The damage bonus improves by 100 percentage points every two weapon tiers--for example, it does not improve for a 4-star weapon. This is slower than many characters improve, so Robyn seems less appealing at middle levels than he does at low levels.
 * A bunch of arrows fall in a space half the width of the screen, dealing many small hits.
 * This doesn't usually do a lot of damage against any one target, and it doesn't travel down the screen to help with waves of enemies, but it helps with large bosses and it is difficult for players to completely dodge it.
 * Sometimes Robyn's hawk attacks a single target for high damage.
 * With this, plus his Skill Attack, plus a pet, Robyn has a lot of attacks that chase single targets. This is useful in the Arena.

 * Pros:
 * Lots of targeted attacks to kill bosses quickly.
 * Cons:
 * Ultimate does not travel down the path.
 * Single-target attacks clear away waves of enemies slowly.
 * Weak at middle levels.
 * Overall value: Average
 * Pros:
 * Lots of targeted attacks to kill bosses quickly.
 * Cons:
 * Clears waves of enemies slowly--only Vincent and perhaps Jeanne are worse.
 * Overall value: Low
 * Pros:
 * Lots of single attacks that chase enemies. The high number of attacks makes dodging difficult, especially when the enemy is in range to be hit by Robyn's basic attack.
 * Ultimate is difficult to fully dodge.
 * When Robyn stacks up high-level bonuses, he becomes very powerful. A Robyn with ascended gear is very strong against players.
 * Cons:
 * Weak at middle levels.
 * Basic attack does not chase enemies.
 * Competes with Vincent for potions and resources, which is a problem because Vincent seems better until you reach the endgame.
 * Overall value: High
