Fate/Extra フェイト エクストラ Perfect Patch Changes Checks Part 7 Glass Cannon Caster Vs Rider 1st Elimination Battle and Post Events No Hack

I guess I'm a lot slower here than in my Arena victory, as I was able to end it in turn 4, while it is surely 3 in the Arena. Did Rider's HP get bigger in this battle compared to the arena one? Scratch that, it was still turn 3 at attack number 4, while the Arena was turn 3 attack number 5, so I guess the arena one is stronger, has 3094 HP, so I guess it was due to me leveling more after the arena that I beat her faster in the elimination than the arena?
