Skadi Crit & Big Doggo dmg 8.5

Ok, my biggest issue is with the split push build, the relics mainly.
Teleportation glimph is a very bad relic, even on solo lanners and should only be used if you're doing a boots rush in solo, in adc and mid (which are skadi's main roles) you should never even consider the relic, regardless on whether you're going to splitpush or not.
Frenzy is a support's relic, yet again it should not be built on either a mid or adc regardless on whether you're aplitpushing or not. Beads and aegis are simply way better relics.
As for the build itself I would disadsentivise going for crit with a transcendece build, you'll want to go as much ability power as possible if you're going transcendence and hence for skadi mid I'd suggest going a hunters cowl and morning star for a starting build, if you wish you could also go bluestone pendant in place of cowl for that extra early damage as skadi's early pressure in mid is straight up unrivalled for the first 5 levels.
After this you'll want to go into a transcendence then ninja tabi whilst starting with your first pen item, being crusher/jotumns/brawlers beatstick, all 3 of these are fine here, however jotumns is the best right now.
After this you'll want to go a big power item or more pen, so anything like double mace if they have a healer (which has fallen off but can be done) or maybe a heartseaker or even a blood forge if you're getting a lot of kills as the shield helps drastically, for final item you'll want yout big %pen item so titans bane is the go to for ability based hunters, the build above would be way better for skadi mid than your given split push build as it plays around skadi's ability based nature, she wasnt to burst the enemy down within a second as she has no mobility but very, very high base damage for a hunter a long with mobile block stacks, skadi also sucks with crit as she has no AA stim inside her kit that she can consistently activate, which is usally why she goes ability based and prefers to be in the mid lane, the other ADC builds are fine, they are the meta builds for every hunter adc, even skadi who wouldn't usually go crit goes crit in this meta due to the strength of the stat, in mid however, if you have a physical adc+magical jungler i'd suggest not going your split pusher build (which looks to be like the mid build for skadi) as not only is double crit bad (as it almost mandates 4 spectral armours) but it just doesn't fit skadi's place in mid where she wants to snowball her lane then rotate and gank either duo lane or catch the jungler off guard and kill them. Also failnot isn't worth going, I know, it's funny to watch kaldr crit, but the nerf it took in 8.3 unfortunately killed the item.
Otherwise, the build is fine, just the splitpusher build needs improvements.

Main build is fine now. For Dog damage build, im not 100% sure it makes sense to go Hydra's, i'd rather just get Jotunn's which helps Kaldr more (your 2 doesen't proc Hydra's and also it's iffy with her kit anyway and Kaldr benefits more from Jotunn's base stats). Also Arondight cannot be built on hunters, it's a Assassin / Warrior only item. I'd suggest swapping Hydra's for Jotunn's and Arondight for Titan's Bane or Bloodforge. Not sure there's a point in the "anti-tank" build since the current meta crit build is THE Anti-Tank build (well more like Anti-Everything build cause it's broken).

Hello Everyone! If you have any questions let me know! I truly believe this is the new meta for skadi. Any skadi using hunters cowl is playing skadi wrong. Skadi this season is a late game carry and ornate arrow is stupidly strong after buff. I haven't seen anyone mention how good this item is and its very surprising. I think the people who are using ornate arrow are keeping it quiet so they dont nerf it. Build the crit build and get some freelo. I've carried the past 25 games with skadi. And I currently have an 80% winrate with her.
