Okay, Astarta's solo run:
Astarta, LG human necromancer, 18/18/17/18/18/3
Looted Gorion's body. Found a Web spell. Travelled to High Hedge. Traveled to Beregost. Killed Algrenon for his cloak. Reputation dropped to 7. Traveled south. Charmed a couple of Ogrilons and a Flaming Fist paladin. Used them to kill some hobgoblins. Got Mirriane's letter and Boots of Stealth. Traded letter for a ring +1 in Beregost. Sold boots. Bought an Ammo belt from the smithy.
Travelled to crossroads area. Used Algrenon's cloak to charm some gibberlings and Xvarts. Used these as cannon fodder to charm more enemies (of course, some were killed in that process). All in all, defeated 3 groups of gibberlings/xvarts and left 4 alive. Used those to charm several nearby wolves. 2 Xvarts survived. Used the wolves, Xvarts and a familiar to kill Elminster. Reputation dropped to 5. Got a Magic Shielding potion. PC hit level 5.
Killed the local Ogre afterwards, got the Girdle of Piercing.
Travelled to Friendly Arm's inn. Found a Ring of Wizardry. Attempted a fight vs a local wizard-bounty hunter. In SCS, that one is immune to Magic missiles thanx to a shield prebuff, and also has Mirror Image and Horror. Hist 1st lvl offensive spells are weak though - MM and Sleep. PC is immune to sleep, being lvl 5. And immune to MM via Shield prebuff. So the only one dangerous spell is Horror, and it has a short duration. Anyway, PC was successful with a sleep spell, and the fight ended there.
Bought a gem bag from the tavern. Uncovered Jhoira's flamedance ring from some goblins.
Traveled to Nashkel. Uncovered and sold an Ankheg plate. Bought a Potion case from the store.
Traveled to High hedge. Avoiding all enemies, traveled to Talantyr and bought a Scroll case, as well as an Invisibility scroll and a scroll of Skull Trap.
Traveled to ankheg area. Tried to charm local bandits and use them as fodder vs Ankhegs thus not having to use the Invisibility scroll. No luck. Bandits are charmed for only a very short time. Charmed a local paladin, but he died quickly, and the Web spell which Astarta shod wasn't that effective vs the Ankhegs either. Sigh. Read the Invisibility scroll, and traveled north. And further north to Ugloth's beard.
Charmed Dushai. Used magic missiles and melee to kill her. She drank 2 extra healing potions unfortunately. Got the Ring of Free Action and another Web scroll.
Traveled to Durlag's tower. Using Web and the ring of free action, Astarta managed to ensnare and kill with projectile spells the two Battle horrors. Hit lvl 6. Next she rested, and attempted a more dangerous fight - with 5 dopplegangers. Astarta didn't engage those until she shot 3 webs off-screen at them, then a Skull trap too. A second skull trap was shot before enemies managed to engage her, and killed 3 of them. The other 2 were subject to Magic missiles while PC was running.
XP, gold and scroll farming: by setting Skull Traps in the spawning point of the dopplegangers, Astarta raised her level to 9, got about 65k gold after selling jewellery dropped by the dopplegangers, and also got several good scrolls from the dopplegangers and sleep-interrupting gnolls: ProPetrification, Fireball, Lightning bolt, Haste, Slow, Dispel Magic, Non-Detection, Flame Arrow, Monster Summoning I, Protection from Missiles and other. Several scrolls were dropped more than once, like Dispel Magic. Also she got 2 good Lightning wands (BG2 lightning wands shooting six 3d6 lightning bolts with each charge).
Raised rep to 20 by donations and completing Jhoira's quest and Firebeard's quest. Bought the Robe of Good Archmagi, Horn and Claw of Kazeroth, Ring of Invisibility, Greenstone Amulet, Emotion, Greater Malison, Remove Curse, ProFire, ProCold, Minor Spell Deflection, +3 Martial Staff, Cloak of Displacement, Purple Ioun Stone, Amulet of Protection +1.
Joined Garrick. Killed Silke by using Greater Malison + emotion. Used summoned monsters to draw her out of hiding. She didn't waste any spells at PC, who was well buffed, with Spell Deflection on top. Dropped Garrick as his pickpocket skill was low.
Joined Imoen. Raised her detect trap skill to 100% and her pickpocket skill to 95%. Bought some potions from the Durlag's tower merchant. Traveled to Ugloth's beard. Used Imoen to pickpocket Shandalar (pickpocket 155% with Master thievery + Perception potions). She didn't fail. However Shandalar doesn't have that much useful spells. He carries Greater Malison, Otilulike's sphere, Emotion, Feeblemind, Remove Curse and Spirit Armor scrolls, from which the only one useful which PC doesn't have is Spirit Armor. Oh well. Used Imoen to disarm some traps in Durlag's tower. Bought a wand of Fire from Durlag's tower merchant.
PC cleared (under ProFire) some nasty Phase spiders in the 1st lvl of Durlag's catacombs. Imoen entered the library and disarmed the traps. Loot: Monster Summoning III, MGoI, Cloudkill. Very useful spells for PC. Also obtained (from this same level) several antidotes and a Wand of Monster Summoning. Recharged the wand by selling-rebuying.
Ditched Imoen in the Durlag's tower area. After all, she'd be needed mostly here. As a side note - each time before leaving the area, the magic traps were re-set at the spawning point of the dopplegangers, so they don't be a nuisanse when the tower is revisited.
Nahskel: PC now entered the tavern and challenged the enemy bounty hunter cleric. Used Web to get rid of her.
Nashkel mines: Nothing scary really, especially with Cloudkill and Fireball. Mulahey tried an Unholy blight, which was ineffective due go MGoI. Got the boots of Grounding for some electrical resistance. Used some fire wand charges to quickly clear the kobolds. ProMissiles helped enormously here since those Kobold commandos hit very often (dunno how or why).
Travelled to Nashkel. Reported about mine trouble. Fought Nimbul...frankly, 2 ogre berserkers summoned via the Monster Summoning III took care of him. Got the boots of Avoidance - a not very useful item to PC, but still kept - who knows what may happen tomorrow
Travelled to Beregost. Fought Tranzig - loot Glitterdust scroll. Rested. Went to the eastern part of the city, talked to Elminster. No point in killing him now

Buffed very well, travelled east. Reloaded because of bug (2 enemies spawning instead of 4). Molkan's mercenary group approached (those are usually stationed at Gullykun). Web + Cloudkill finished them. Rested. Travelled to Pedvale. Talked to Raiken (used several wand charges - summons and fire - to eliminate 2 groups of Black talons, who almost killed PC). Rested. Buffed with longer-lasting buffs. Talked to Raiken. Was transported to Bandit camp. While running, cast shorter-lasting protective buffs. Astarta had just finished casting the last one, when enemies approached. The whole camp came after her. No matter. Combat started with Web, Web again, Greater Malison, Cloudkill, Cloudkill...and there were only 2 enemies alive after that - but webbed. Looted the bodies - a Spell Thrust scroll. Rested. Entered the main tent. Talked to Sai. Buffed well. Cast MGoI as last buff. Opened chest. Lightning trap ineffective. Chapter ended.
Went outside. Loaded due to a bug - 2 amazons appearing instead of all 4. Amazons appeared (the ones usually found in the Tomb Valley). Web + Cloudkill...
Travelled to Cloakwood after resting. Uncovered the Non-detection cloak in the first area. Fought some spiders in the second area - used Fireball mostly, but Cloudkill is just as effective vs most of them. And Magic Missiles too. Got the Spider's bane - to be sold. Travelled to Wyvern area almost undisturbed...well, the ones who tried were webbed and fireballed. Entered the wyvern cave. Was attacked by a baby and a big wyvern. Went outside. Big wyvern followed. Used Greater Malison + algrenon's cloak to charm it. Sent it vs a group of local bears, who killed it. Webbed the bears, killed them, collected the head.
Cloakwood mines: Used an invisibility ring charge, scouted a bit, stood right outside of enemy sight range, shot 3 webs, then a greater malison, and all enemies were permanently webbed. Used fireball spells and wand charges to eliminate all enemies. Got a potion of Magic shielding, and other useful stuff, like Fireshield Red wizard scroll.
Lvl 2 of the mines: after killing all guards on lvl 1, went downstairs, and used 2 off-screen cloudkills to clear the first 2 rooms. Not that there are many guards in them, but if they aren't killed outright, they sound the alarm and the whole bunch comes to visit. Also that way PC looted some good potions, including an Oil of speed. Uncovered the secret doors and killed 2 Ghouls via MM.
Went back to lvl 1 and rested. Sleep interruptions got too much - finally used a monster summoning wand charge to summon some bodyguards. Of course, right after that there were no more sleep interruptions.
Went downstairs, through the secret doors. Talked to Riti. Shot a off-screen Cloudkill at the big enemy group (the one with Hareisan). The basic idea was to kill all minor enemies, leaving only her for 1/1 wizard fight (well...at least she would be alone, and PC can gate an army anytime), but the Cloudkill actually managed to kill her too. Strange. I thought SCS prevents things like that. Looted many potions and some scrolls (nothing new).
Rested on the level above. Went to the level below afterwards. Cloudkill took care of many enemies, but there were many more. PC was looting the armoury when Natasha showed at the entrance. Not wasting time, PC quickly summoned monsters, which blocked Natasha's way. Natasha managed to remove PC's buffs via a single Remove Magic spell. Oh well. PC kept summoning monsters, which Natasha repelled to some extent using Fireballs and other spells. Thankfully, PC was well hidden from the Fireball effects. Finally, Natasha fell to the superior monster numbers (she had depleted her spells). She drops a Haste scroll, but PC already has that.
Looted this level almost completely.
Well, next is Davaeorn...have to think a bit on a strategy, and maybe travel back for some items.
