Well if she was indeed level 1 or 2, no way on earth she could do so much damage with Blade Rush. It would require a specific setup of late helix choices to be able to deal that much damage in a single use of Blade Rush. Hell, there’s a reason people are having a hard time completing that “deal 2k damage with one use of Blade Rush” lore challenge, and it can really only be done in PvE with a super specific build and loadout.
On the other hand, Blade Rush CAN crit when it hits the head. But to the point of doing 800+ damage, I really don’t think so. BR at level 1 inflicts according to tooltips 34x4 damage, I suppose it is about 50x4 at level 2, so 200, so 25% of 800. No way each projectile could crit for x4 damage.
I’m curious now if there are cheats like that capable of augmenting skill damage or making a level 1 character behave like a level 10. It is pretty impossible to deal that much damage with level 1, 2 or even 3 Blade Rush, and get that many kills in 4 minutes…
Maybe @Slif_One could confirm ?
