I apologize ahead of time for this question. But it came up in tonight's session. Lets say that you have a Helm of Brilliance, and a Longsword +4.
The helm states that if you use its ability to create a flame blade, it retains its previous abilities and gains the flame blade. Now... the next part is where when looking online no one knows what the flame blade was ever supposed to be, so the consensus is... use the Flame Toungue sword.
Next.... the Flame Tongue sword has +4 against undead... (see where this is going?). So What my friend is trying to tell me is that because it says it retains its previous abilities, that the +4's would stack with each other effectively making it +8 vs Undead.
So, have I just been playing wrong all these years, or is my friend correct? I basically looked at him like he was crazy, and there is no mention of weapon bonus stacking in AD&D anywhere on the internet to indicate otherwise, Thanks.
This would also apply to any weapon with multiple combat bonus attributes even without the helm involved. So if it was a regenerating, cold based, undead creature of some kind, The flametounge would be +1, +2, +3, +4 for a total of +9. This seems ridiculous to me. But if I am wrong, I can accept that. I have never had this question come up before when were played originally decades ago.
