Condolences Wise, you did well.
Alesia and Golden, belated thanks for your warnings and tips. Stun is less of threat for Isa now that she has the Sword of Arvoreen. The Reflection Shield is not yet usable though. (It's not changed into a Buckler by my version of Rogue Rebalancing).
Dyara, congrats on beating Firky 
Gate, keep up the good work!
Isadora, Halfling Swashbuckler, BG2 update 3
Isa paid a second visit to Watcher's Keep, this time entering the place, and did an interesting discovery there:
She didn't need +3 weapons to hit Stone Golems. Her +2 Scimitars sufficed. (I was pretty sure that in my BGT install +3 weapons were needed, but now I'm doubtful.) The rogue's stay was going to be a short one though. She picked up some loot, including a returning Crimson Dart, but was denied the opportunity to investigate further (and aquire an ammo belt) when Vampiric Wraiths came after her and level-drained her.
The Keep would have to wait till she was ready for it.
Back in Athkatla Isa attacked and finished Rayic Gethras' Stone Golems that she knew vulnerable to her blades. She took the late wizard's vacant property for herself. It was a spacious home, and its location was convenient, close to the guild house she soon hoped to lead. In the guest room she hid several items that had some use or other but didn't fit in her pack.
A young boy named Delon told Isa of killings and disappearances in his home town Imnesvale, a village in the Umar Hills. The rogue decided to travel there and see if she could be of any help. She slew a Killer Mimic and a rebellious Stone Golem for a local Cowled Wizard, and received a nifty short sword as a reward.
Isa's research hinted at evil happenings in the nearby Amanautar Temple Ruins. She encountered them infested with different types of undead and two Bone Golems. With some patience and with lots of (extra) healing potions, the Halfling managed to clear the place.
Near the exit Isa slipped past a dormant Shadow Dragon, and back outside she used a scroll of PfUndead to exterminate a Shadow Altar, a Shadow Warrior and a Shade Lord unmolested.
Isa was unwilling to postpone dealing with the evil creatures (and allowing them to make more victims), and a rather pragmatic lass at heart, so she chose a scroll of PfUndead over a more 'heroic' intervention.
(In Athkatla she was proved right, as battling Vampires alongside Arkanis Gath and Ryokoi resulted in her level-drained once more.)
Isa's next move was to take on the Slaver Stockade, as she had promised Hendak, former slave, and the Copper Coronet's new manager. In the sewers leading to the slavers' stronghold, she noticed an increased precision in her attacks with the off-hand (level 16 was reached, a 3rd pip went to TWF, mostly for RP reasons: her adventures hadn't yielded her any appealing weapon that she was unfamiliar with and wanted to train herself in).
Solving a riddle saw Isa rewarded with an enchanted greatsword that conferred several immunities upon the wielder. The Halfling found it too hefty, and sold it.
Having quaffed a potion of clarity and applied an oil of speed, Isa snuck into the Slaver Stockade in an almost care-free manner. She chose her first target, a Priest of Cyric, and dispatched him before he could cast a single spell.
A Divine Wrath helped her control a crowd of fighters that closed in on her, but she nevertheless found she had taken several blows once she was done with the ruffians.
She slew two Trolls (Tuigan Bow and acid arrows) and two Tuan-Ti, and rescued a couple of child slaves. A second potion of clarity allowed Isa to safely dispatch a second contingent of slavers, which included two wizards.
The Halfling was thanked by Hendak and walked off to the Docks District to finish the job she had started for Renal Bloodscalp.
A potion of defense and an oil of speed were very helpful against Mae'Var's men, but even so, she suffered several nasty stabs on the first and second floor.
These events warned Isa to be extra careful in the cellars, where Mae'Var and his best assassins awaited her. Isa set four snares near the stairs so that she could safely retreat if necessary. Mae'Var did Isa a favor by injuring his own men with a Sunfire.
However his assassins were as dangerous as expected.
Both Kitthix and Isa's Berserk warrior were toothless before Mae'Var's and his men, but her Efreeti handled the enemy with surprising ease.
Renal proved true to his word: with Mae'Vars fall, the guild house was Isa's.
In the same Docks District, Isa eliminated two evil wizards for the local Harpers,
and she looted the Harper Stronghold before they used her as a tool to kill Xzar, the Necromancer she had briefly met on the Sword Coast.
She visited Gaelan Bayle and paid him 15k GP hoping the Shadow Thieves would bring her closer to Imoen. Shadow master Aran Linvail rose a number of barriers though. The first two, monitoring a shipment and dealing with two betrayers and their contact, were no big deal. But the third task she was asked to perform, eliminating the Shadow Thieves' rivals, a guild of Vampires, all by herself, was too much to ask of her at that point. She told Aran Linvail she would first have to find a way to handle the Vampires' draining attacks.
At the guild the Swashbuckler bought two new items, a ninja-to and a buckler:
This left her with almost no gold, so she accepted another commission.
She would clear a noble family's keep, the d'Arnise Hold, that had been invaded by Trolls and Yuan-Ti. The Trolls, including Spirit variants (with no spell-casting abilities) fell easily enough. Despite her non-proficiency with bows, her Tuigan Bow and acid arrows proved very effective. A Yuan-Ti Mage too, learned of Isa's skill with her bow, and it helped her by getting caught in its own Web.
The Halfling also dispatched a group of Golems, but found her weapons useless against a Clay Golem. This worried her. She slew several more Trolls before she traveled to Athkatla on Guild business.
In the city she dealt with a group of Thieves loyal to Mae'Var and the Night Masks, and she procured 200 lbs of true illithium for Sir Sarles on behalf of the Temple of Helm (I also had the fake illithium but forgot to drop the real deal on the ground before speaking to Sarles).
Isa traveled to Trademeet to buy the Blackblood Club, a weapon she hoped would be effective against slashing-immune creatures such as Clay Golems. (Sarles had helped Isa reach level 20. Although Staves are my preferred blunt weapon, for dual-wielding Isa Clubs made sense, both mechanically and for a RP reason, the Blackblood she had already seen.)
The Halfling returned to the d'Arnise Keep, and dispatched the Clay Golem with her new club, as well as several respawned Trolls.
In the basement of the Keep, five Umber Hulks taught her not to try her luck against them:
She was more successful bottlenecking the monsters.
Four traps and an acid arrow finished the Troll leader,
Isa proceeded to melee an Umber Hulk Elder and two Giant Trolls, but only managed to slay the former before one of two Yuan-Ti Mages prompted her to retreat.
With clarity, speed, invisibility, Blackblood and acid arrows the Halfling bested one Yuan-Ti Mage, while running from three Spirit Trolls and a Spectral Troll.
When she was done with said Trolls the other Yuan-Ti wizard fell after a similar treatment.
Isa returned to Athkatla, a richer and more experienced adventurer and thief. Such was her pickpocketing prowess (145), that with the Gloves of Pickpocketing, a potion of master thievery, and a potion of perception, she rewarded herself with a shoplifting tour of the city.
