While it’s true that Nezha as a whole is an amazing frame with many uses, it doesn’t take away from the fact that this one ability turns Int into an almost AFK session.
Nyx is also decent, but Chaos won’t make an enemy that’s capturing a tower stop.
Gyre: Pillage build and unhealthy amounts of strength bring me a lot of satisfaction
Caliban: Nourish and Primed Flow give him as much energy as he needs to shine. His 4 is kinda like Xaku’s 3, but where Xaku’s 3 lasts more and is wider, the defense strip from Cali’s 4 is permanent and drains both shields and armor at the same time (also it stacks an infinite amount of times
Zephyr: has it all, many fun and viable helminth combinations (coil horizon to put enemies into tornado range from further away, silence to negate eximus and make overguarded melee enemies your only threat, spectrorage to generate energy from tornado kills), AND she’s the best frame for solo SP Circuit (in fact, i’ve never gone levelcap yet, but i believe Zephyr with Silence and Assimilate Nyx with something to slow overguarded melee enemies down OR Dispensary is a perfect duo). Also, if your starter frame was Volt and you switch with Zephyr but miss the speed, Jet Stream has you covered
Also…
Do not, EVER, use Target Fixation on Zephyr, it’s so good it’ll ruin the game lol
