Having trouble with mags in boss rush? Here's some tips
1. GET GOOD! Jk but here are some real tips to help you out.
2. hyperion and the hood for mags. hyperion hit him with L1s.. stack up that incinerate or the hoods l1 or l2 will deal damage but it won't hurt you because its not direct damage.
Goken any champ that applies energy damage or bullet damage that has another effect: ice man, iron man, SIM, WS, punisher, Modok, Mephisto. Wolverine might be handy if you can make him bleed a lot and you get lucky with regen.
3. no L3s though. Only L1 and L2s due to his sig ability.
Hope this helps
