Don't you remember? I beat the way of the bloodmage into you earlier with a bone. If I have to use words I will though, listen carefully young one. My tip is to always use silence, constrict, and stealessence and not just the damaging skills. Start off with silencing a wizard, then use the deadly combo, boilblood, soulleech, and drainsoul. You should also use constrict often, especially when you need to heal. I find it very easy to just constrict the player, then use the combo. Don't forget stealessence, always steal a samurais windwalk and any other buff like might or wisdom. (It's a good skill when fighting a bard) Always remember to use drainsoul as soon as it's cd runs out, if you are on half a heart, it's a helpful skill, just drainsoul + constrict then chant.
Well there you have it, don't forget, our next lesson is tomorrow, this time I am bringing two bones.
Also, what Falker said is not good information... bloodmage is really not a team healer.
