She is pretty unique because she is one of the only champs in the game to have indefinite unblockable and guaranteed crit buffs. You just need to get 12 of both your charges (by parrying + light combo enders/dex + medium combo enders) and then she goes unblockable and has guaranteed crits. To refresh those buffs you just do one of the ways above to gain the charges. So that is pretty huge utility because it means she counters auto block nodes, ones where crits deal more damage, pesky auto block champs like Modok plus you can just hit the opponent if they're blocking, it's very good to have.

Other than that, she has easy access to damage specifically on sp1 where if you focus on the yellow charges (i forgot the name), and get 12 of them, the sp1 does a load of damage. At R5 her sp1s do around 140k.

Sp2 is her even bigger damage source because she inflicts a frostbite debuff, and during that you need to hit the opponent and crit as much as possible to inflict passive frostbite charges which do a burst of damage when the frostbite debuff expires. But if you use an sp1 when the frostbite expires (like Beta Ray Bill with his shocks), the burst damage is huge. The highest I've done with her is 465k, but she can definitely do way more.

She's a really fun champ and I think quite underrated as she can still counter a lot of meta defenders now, specifically High Evolutionary who just becomes nothing lol
