How to beat the Grafted Scion in the Tutorial + Reward - https://www.youtube.com/watch?v=KdlzIuRpPKg

Since this thing loves its basic 8 hit combo, an easy way to defeat it is to bait it. The first 2hits should miss as long as you move backwards. Dodge the second of the next 2 and keep moving backwards (+left or right to avoid getting cornered) and the next 2 will also miss. Moving backwards and left is optimal bit right works too. Of the final 2, again move backwards for the first but forward dodge the last and attack. 1 attack is safe but you can try a second one after getting used to it. Next up, his high jump and smash attack is easy to avoid by moving backwards and is a safe 1 to 2 attacks. You can punish the scream by dodging towards it during the final second of the attack. When it stands up and attacks the ground, wait for the second part of the attack, a heavy smash on the ground that can be punished somewhat safely (it can cancel out the final part of the recovery animation and attack but 1 attack is safe regardless). While in the buff move, it deals more damage and chips through shields but doesn't last long. When it stands up straight I always stay away cause both of its moves from there felt like oneshots so I didn't try taking advantage. In general, the Vagabond's 100% phys shield is very useful for this fight as long as you only count on it for the random attack that you failed to outspace via moving backwards and although it takes a bit, unless you mess up, this is an easy albeit a bit time consuming way to beat it. And the rewarded shield is perfect for shield users. The best place to face it is around the central ring of the arena (tutorial) since it helps you know how far away from the cliffs you are.

Any weakness on her?

Fire is her weakness

Cheesed it by shooting bolts at it from elevator room
