This is my heroic team. There is basically nothing that can kill this team other than this exact same! lol. trust me. i love this team because it does soo well.

It is...
Darq the Corrupt at Level 1
Astrus at Level 2
Zenphret at Level 2

Also as a sidenote i was wondering if MB in dungeons can go through walls or not.

kzar nabar at L1,queen corella at L2,and lyra fairhaime at L1 is nasty other than it's lack of healing and range. As for your other question, sorry I can't help.

cool that looks like a good team

yea i won my first dungeons tourny with it, i was 3-0! thats how i won Slobber! I killed Magebane in one hit and the Master Adversary in two hits. and in all three of my dungeons matches i destroyed all of the opposing team members! except in the final battle my opponent managed to get lyra fairhame out with two chests, but i still won that game by destroying all of his other 3 members and getting out with more gold and 10 minutes to spare

yes magic blast can go through walls in dungeons.
Just remember to half your range

ok, well still i rest my case, my team is awesome. it might have been a different story if Darq didnt have Magic Immunity!

If you want to make your team even more "vamp" themed and close combat friendly, use Vija of Vladd at level 1 instead of Zenephret and pump astrus to lvl2. This gives you one more venomer, and put astrus 1 lvl away from toughness and a flat 3 damage. This one also would have won me my last tourny if it wasn't for the dreaded mirror match. His Darq got the first hit and I missed both the counter AND my attack.
