I apologize but this requires some BG1 knowledge:
What monsters appear in both BG1 (TotSC included) and IWD2?
NOTES:
_BG1+Totsc and
not BG2.
_Monsters which can only appear from summoning spells do not count.
_Monster "sub-classes" (like gnoll elite, gnoll slasher, gnoll berserker) do not count as separate monsters (all are gnolls).
_No need to mention any sub-classes just give the monster name.
One example is spiders, which include huge spiders, giant spiders, phase spiders, sword spiders, wraith spiders and whatnot.
Give me...
10 more.
HINT
remeber TotSC
