Great, I hope he works well for you. Here are my thoughts on your questions:Hey [MENTION=83242]dave2008[/MENTION] this Strahd version is perfect for my 6 players party + allies.
I have a question about the longsword attack.
Is it a +3 magic longsword correct?
Why it does 6d6 and not 1d8 ?
what happens to the necrotic damage replaced in this version with lightning damage. ?
1) Yes it is a +3 magical weapon, but it was supposed to be a greatsword. The idea was that he summons his armor which includes a greatsword (Strahd's Animated Armor, pg 227 of CoS).
2) I modify damage based on strength. With his 22 strength giving me the strength of a Huge monster I allow him to inflict damage as if he has a Huge weapon, thus 6d6. However, I forgot to change multiattack (and the name of the sword attack) when I made this change. You should modify his multiattack to be:r greatsword or unarmed strike. If you want to go with a +3 longsword (so he can still use unarmed strikes) I would increase the lightning damage. My recommendation for a revision would be:
Longsword (VAmpire Form Only). Melee Weapon Attack: +15 to hit, reach 5 ft., one target. Hit: 22 (3d8 + 9) slashing damage, or 25 (3d10 + 9) slashing damage when wielded 2-handed, plus 14 (4d6) lightning damage.
3) The greatsword with Strahd's Animated Armor (pg 227 of CoS) inflicts lightning damage.
