First and foremost, go with the combat skill you will
most enjoy playing.

Start with 100 in your combat skills and work from there. You will "eventually" need 120 in Melee, Tactics, and Bushido based on the Youtube guide you're following. The 120 Tactics scroll will be your biggest expense for scrolls.

You do not want to use a shield, holding a shield will work against you when fighting. (That is not the way of a Samurai)

Healing instead of Bushido is not a Sampire. Learn to heal by doing damage in Vampiric Embrace form.
Strength is Hit Points, so get them as high as possible
Your Dexterity is Stamina which controls your swing speed. You need to max swing speed for you given weapon.
Intelligence doesn't have to be high, but Mana needs to be high enough to maintain all the specials you are using. You can get manna from items.
Lower Mana cost, LMC, has to be a minimum of 40, this is essential. Different suit materials will increase LMC to 45 or 55, depending on material.
Questions:
Is you character an Elf? This gives you several advantages. 20 extra mana, night sight, and sexy ears.

Are you currently at a 225 cap for stats with a new account, or are you on your old account with 230 cap? You will need 255 and 260 is ideal.
