You don't HAVE to use Chivalry.
Template wise I'd suggest:
120 Mace
120 Tact
40 Necro
80 SS
120 Bush
120 Parry
120 Anat
Or adjust as you see fit.
Things to consider with the suit. Wraith Form gives 15/-5/0/0/-5. Protection if you chose to use it, if you're human is -14 physical, any other race -15 physical. You want 40 Necro for 100% success with Curse Weapon, Tactics, SS, Bush, Parry and Anat levels can vary a lot depending on how you want to play it. I'd probably go with 120 Bushido for the Whirlwind damage. You could replace Parry or Anat with Resist if needed.
I'd want minimum of max resists, 100 di, 40 lmc (preferably 55), 45 HCI (40 if gargoyle), 45 DCI (20 if refining), 25 HP. You'll need to work out your stam/SSI needs first for the weapons/specials you intend to use, there's a calculator on uoguide. You'll probably also want to pack on stam/mana increase and/or stat increase. I personally dislike playing with less than 150 Str/HP (without needing bless/pots), so usually have 25 Str on the suit too. If you plan on playing a more caster version with higher Necro you'll probably want to factor in LRC over something else.
