Just like the first Icewind Dale. Go into the icewind2.ini file and add Cheats=1 beneath the Game Options title and save it. Now during game play just hit Ctrl+Tab and that crazy little bar will show up at the bottom of your screen.

Type in:
ctrlaltdelete:enablecheatkeys()
the only really cool cheat key of course is Ctrl+R which completely heals and ressurects the character your mouse is sitting on. Ctrl+J will place your PC's anywhere your mouse is on the screen. There's a few more you can mess around with.

ctrlaltdelete:addgold(#) - adds pretty much as much gold as you want.

ctrlaltdelete:setcurrentxp(#) - adds pretty much as much xp as you want to all or just a few or one character.

ctrlaltdelete:createitem("00x,#") - creates any item in the game you specify. Here are a few starters that will sorta give you an idea of what you can do:

("00amul15") - Amulet of Intellect adds +1 to your Int ability.

("00arow06,100") - Arrow of Biting. Items such as arrows and bolts and a few others similar to these you can add 100 or 200, etc. Other items like swords and boots don't work like this.

("00ax1h76") - Returning Throwing Axe.

("00ax2h96") - Axe of Cleaving +5.

("00bolt93,50") - Bolt of Stunning. Like arrows you can add more to these because they're projectiles.

("00bowc92") - Composite Longbow of Spell Resistance.

("00bowl97") - Longbow of the Shield.

("00bowp99") - Composite Shortbow of Endurance +2. Adds +4 to your Con ability.

("00bows89") - Silenced Shortbow +1. Adds +2 to your Move Silently skill.

("00brac03") - Bracers of Defense +3.

("00chan05") - Splint Mail +1.

("00club98") - Corrosive Club +2.

("00dagg86") - Sure Strike Throwing Dagger.

("00flal90") - Vampiric Flail.

("00helm07") - Helmet of Charm Protection.

("00leat87") - Studded Leather of Luck.

("00mace92") - Mace of Stunning Frost Burst.

("00plat03") - Mithral Field Plate Armor +2.

("00ring67") - Ring of Magic Missiles.

("00scrl06,10") - Protection from Poison. Just to let you know, I haven't figured out yet where the rest of the scrolls are hiding. So if you figure it out, POST IT.

("00shld11") - Large Shield +1.

("00slng99") - Sling +2.

("00sper94") - Spear of Wounding.

("00staf81") - Staff of Invisibility.

("00swdb92") - Static Bastardsword.

("00swdc92") - Scimitar of Hell's Fire.

("00swdl84") - Spellward Longsword.

("00swds85") - Reflective Shortsword +1.

("00swdt90") - Blessed Greatsword +2.

("00wand05,10") - Wand of Lightning. I think you can stack wands as you can arrows or bolts. Not really sure.

These are just but a few of the hundreds of codes you can enter. I've had the game for only 2 days so I'm still searching for all of them because I have nothing else better to do. On another note, I am in way in league with the folks at Black Isle or BioWare or any of these fine people responsible for this Icewind Dale II. I'm just a fan of Forgotten Realms D&D. Thank you.

the light of cera sumat(large sword)=ctrlaltdelete:createitem("11HFSLHE",1)

NOTE: THIS IS THE BEST SWORD IN THE GAME BUT IS ONLY USABLE BY PALADINS, IN THE CHEAT SCREEN INSTEAD OF SHIFT 2 BEING ", SHIFT# GIVES YOU SPEECH MARKS
