I train all my sampires like mages first. I lock dex at 10 and raise int and str. I train necro first. Get a 100 LRC suit with 40 LMC. I allow spirit speak, med, and focus to raise naturally. When at 50 necro/50 ss use a dark wisp. When you hit about 72 necro get into lich form. You will GM focus and then med. Keep at the necro trainin until 99 or 100. Once this is done, train chivalry while you have your best mana regen and a large mana pool. Train to your target, then train bushido (confidence then counter attack) to 70. Now all of your support skills are set or started and it is time to turn your char into a dexxer. Set your int to lower and raise dex. Cap str at your target value based on your max stat cap. Always put dex to 125. Lower ss, focus, and then med in order as you progress. I train parry next; buy 40 parry, 40 healing, and 40 anatomy. I temporarily train healing to help with the sheep. Let anatomy raise too while training sheep. Don't forget you have bushido so either remove it temporaily via soulstone or adjust your technique. Once complete with parry training switch to weapon training. Buy weapon skill and tactics to 40. Head to Despise and lighrtning strike lizardmen, then ettins/earth els. Then at 80 go to Yomatsu mines and fight the dc and earth el spawn right at the entrance. Once at 100 head back and start tackling the warriors. You can hit 120 weapon, 120 bushido, 100 tactics, and 100 anatomy all in the mines.
Anway that is how I train a sampire. It has served me well across multiple shards. I find the suit is the harder part to setup. Imbuing makes it immensely easier. I'm training my second artificer now so I can outfit and prep weapons for my cross-shard sampire on Origin (where the availability of stocked vendors is lower than other major shards).
