Thanks. Do you think that if it was replaced with a BG2 green dragon (i.e., the creature file) that the fight would be winnable for a party around, say, level 7?
I recall that the fight was darned tough with the original wyvern. With a BG2 dragon (and especially with SCS/SCS II installed) I'd imagine that fight is hard core, given the party's level. On a scale of 1 to 10 for BG1 battle difficulty, about where would you rate it?
Also, is there an option to avoid the fight if it proves too tough?
