HEY my name is jack lantern this my guide for supergirl i can't promise that this can make you get some many kills because my first time it wasn't that much. thank you for seeing this guide and i hope you like it
sword of beowulf buy it your an easy target

world breaker - use this for the bot waves so i can lvl up fast and enemies with lowhealth

BOUNDING STRIKE - very useful you can use you flash superspeed and use DETERMINATION and use bounding strike for your escape or chasing an enemy

DETERMINATION - you can use it for escaping a fight. if you are chasing an enemy this is to use

COMET - if an enemy is getting out of a team fight use this and bounding strike,determination for a quick kill
gameplay:
at first you feel like your squishy but if your build is almost done or done you'll do great dmg to nearby enemies
if your always a target always stay back at your team and use determination if you are ready (don't go too long) use world breaker to an nearby enemy and make sure it has an enemy at the back of it and your othere team mate will attack them make sure you have a arcane green lantern's/poison ivy's healing wave or supergir's stolen power comet is a very useful skill if your in a nearby wall it's like doomsday's Q i think .
now go out there and be SUPER
