Roxie

Roxie is a female Hero who has to be purchased for $2.99. She is one of the original heroes alongside Flak and Skybolt

Description
A pistol wielding engineer who can pierce shields and enhance regeneration.

Roxie is a battle-hardened pistol wielding, carnage craving Engineer. Coasting through hordes of Creeps in a reign of bullets, Roxie increases the fire rate of any towers in her range, which is good news for you.

Utility
Strategy while leveling:

Roxie requires the hardest grind to level up. She is not a hero that can be counted on to level herself up. If you have any gems, Roxie is the hero who needs them the most. When leveling, Roxie's problems are two-fold. Even after getting Exotic Ammo, Roxie might only kill a creep or two before dying. These translate to slow growth as hero leveling is calculated through kills. Secondly, Roxie is very squishy and her Body Armor only does so much when she has such low health. Contrary to what one would expect, Roxie doesn't fight like a sniper until she unlocks snipe. She fights like flak does, getting into firefights with creeps and running out of cover. Roxie will die often. It is only after Roxie unlocks First Aid that she begins to fulfill her role as a supporting defensive hero. It is only after she unlocks Snipe, her final ability, that Roxie gains any offensive use. To level Roxie, keep her in the front lines, and perhaps backed up by your second hero. Take full advantage of double Exp weekends and gems.

Max ability strategy:

Roxie finally shines as a defensive hero when she hits top level. Her IR Goggles are very useful in maps with stealth creeps, saving you the energy that would have gone towards loads of infantry or a tri-laser with stealth detection. Roxie also greatly strengthens infantry with her First Aid healing them every second. She is best put on the rear defensive line, where she can stay away from close combat and snipe incoming creeps from across the map. Keep Roxie behind infantry so that she heals them and gets into as little close combat as possible.

Most complementary heroes:

Offensive heroes would compliment Roxie well. Roxie has low offensive output and could use the support of Heroes like Surge, Scorch, Skybolt, and Flak. A top-level Roxie and top-level Cinder could create an ironclad infantry line. with high shields, fast regen, Cinder's killing power and Roxie's Sniping. A top-level Oracle could also compliment Roxie on an infantry line, though there may be stronger pairs as both Oracle and Roxie are squishy.

How fun is this hero to use:

At top-level, Roxie is useful and fun to use. However, she requires the worst grind to become useful. Leveling Roxie feels like a chore.

Should you invest:

Roxie is cheap compared to other heroes. Even so, she is the last recommended purchase. Raising Roxie to usefulness is hard work. Oracle and Cinder would both fill her nitch just fine if you decide to pass her by. Roxie is valuable and fun to use, once she is raised to her full level.
