I'll taste your blood real quick. “Vampire” student that steals HP, and can potentially bypass crafting a weapon. The "ultimate" roach tactics ;)

Difficulty: Two Weak Playstyles

• Battle Bianca: She plays at a deficit with one less skill (Bloody Hands), and she has average stats with low attack stats and slightly higher armor stats. It is only "playable" because of Blood Transfusion.

• Bloody Hands Bianca: Bloody Hands is a unique level scaling which is not strong as Mastery scaling, and you do take damage from using it. This is the ultimate kit for roaching to second place finish.

Skill Explained

• Bloody Hands: It has no cooldown, and this doesn't build mastery. So you'll have to use all game, hence Bloody Hands Bianca. Good to claim first area, but late game is going to be weaker than Mastery scaling. It does not require weapon craft or mastery-building though, but you will use that saved time to craft more food anyway.

• Blood Transfusion: It has the highest HP recover for any character. Blood Veil can save you sometimes.

General Tips 

• Early: Bloody Hands claims her first area.

• Mid: Get fights for Blood Transfusion. It really shines starting from here. If on Bloody Hands, you can use it against animals if you need to kill them fast. Otherwise, basic attacks work for more EXP hits.

• Late: Blood Transfusion. If on Bloody Hands, stay active to maintain high damage.

Counters

• Bloody Hands Area Damage: You only know the real numbers of her damage by looking at the chat. This will most likely trick you up.

• Knowing when she's on Blood Transfusion: It has a 1 second channeling during a fight, and if you made noises.

• Debuff First: She might not have Blood Veil already.
