Would it be possible to import Twinkle, Icingdeath, Drizzt's chainmail and Aegis Fang from BG2?(Drizzts chainmail is in IWD1 why did they remove it?)

Can be because Drizzt havent surfaced yeth and is unknown to the people of Faerûn

I can try to make them.

Give me appropriate 3E stats.

Was Drizzt's chainmail in IWD1? Where was it? I just remeber finding one of his scimitars (in the Frost Giant cave in the glacier).

You could only get it with shadowkeeper.

Mithral chainmail + 4
Scimitar +3 "Icingdeath" (enchantment bonus +3, attack bonus versus fire monsters and immunity to fire)
Defending scimitar + 5 "Twinkle" (enchantment bonus +5, +2 bonus to ac)
Figurine of wondrous power ( summons panther named Guenwhyvar)
Guens stats:
Guenhwyvar
AC: 4
Hit Dice: 6+6 (or 45 Hit Points)
THACO: 13
Number of attacks: 3
Damage: 1d4 (x2) / 1d12, plus read claws rake for 2d4 (x2) if both front paws hit score hits.

Catti-bries magic items (Khazidhea +4 longsword, taulmaril the heartseeker + 3 bow which never runs out of +1 arrows)
Wulfgars magic stuff:
Aegis Fang a war hammer +5 (which does 2d4+2/2d4 points of damage plus modifiers for Wulfgar's Strength and the weapon's magical bonus applied).
Regis's magic stuff:
+2 luck stone, and a ruby pendant of beguiling (dont know what it does but i thnik it allows you to cast charm person)
Bruenor doesnt have any magic stuff that arent already in the game

in iwd1 there was drizzt's chainmail and icingdeath scimitar but not the defender.

strange enough, icingdeath could be found 2 times
