What's left is 3 boss.
#1: Balthazar
I suggest you go in by Havarian. That's so much faster.
Another tip is to isolate the bugger. He IS dangerous, even if the fight is straightforward between a specialized warrior (Blathazar, the monk) and an overspecialized warrior (you, the barbarian).
Oh, and this being a warrior-match INSIDE swap in the BMU for the AC.
#2: Ravager
Bloody straightforward this is for this character.
I suggest to cast Stone Skin from the boots, Mirror Image from the sword, cast Hardiness, and cast the +4 sword as summon sending it in, than just run in to let the battle rolling.
I suggest use Flail of Ages +5 until the Ravager is Slow, than swap for Foebane (it IS a demon you know). Never mind how "ineffective" your weapons are, you DO damage the monster (who is actually Old Father Baal). If you have like 10 greater whirlwind on you (you should have like 14, but who counts), you'll destroy it.
Oh, don't mind the swords, they are annoying but respawn indefinitely. They are why you summoned your own sword - to gain time using it as distraction.
#3: (A)Melissan
Now put everything you have in your Bag of Holding, because:
- you won't be able to come back
- you won't be able to sleep anymore
- you'll possibly not be able to save between every stages of the coming encounter (bug)
- despite you not being able to sleep, you WILL be able to linger indefinitely between stages. With your natural regeneration (CON > 19), Ring of Gaxxx, Axe of Unyielding, Ring of Regeneration, and that Ioun Stone you stashed probably your regeneration-rate should be in the sky, not to mention consuming regeneration-potions. Still not enough to rely these in battle, but between battles...
As you can just stand around until healed (faster if you drink potions), try not to use up whirlwinds against pool-monsters!
- ALWAYS concentrate on Melissan, as anything she summons goes with her to Oblivion
- cast Hardiness before Melissan re-emerges. You should have a bare minimum of 3, but not more than 5 of that ability (whirlwind is your offensive arsenal).
Detailed battle between me and Melissan:
Stage 1: Before stepping through the Gate cast Hardiness and wear the Big Metal Unit. To dispose Melissan cast Whirlwind (one is prerequesit), and 1 Greater Whirlwind.
Stage 2: Before disabling the pool cast Hardiness. Wear the BMU. When deactivating the pool WAIT until Melissan pushes you away. Only AFTER that start to cast Greater Whirlwinds (4 required). During this fight once I gut stunned (from unknown source, the battle log did not mention it) - stun and Hold Person are the greatest threats to this character as they are unavoidable to happen and means automatic loss 'cause you'll be plumped to death before their semi-infinite duration expires.
Swap into Ice Dragon Scales to fight the ice elemental prince, who'll dispel any other source of cold resistance (meaning scrolls).
Stage 3: Before disabling the pool cast Hardiness. Wear BMU. BE ABSOLUTELY SURE you're wearing Boots of Speed. Stay away the last pool if possible. Melissan has enough HP to last against 5 Greater Whirlwind, but you can get away with just 4 and not dying, so I suggest you spare what you can.
The next pool is Extremly Dangerous, so much as Melissan, so I Strongly Suggest luring away the creatures one-by-one! If you have 2 Hardiness left, you can keep that in mind and cast one if/when needed.
Stage 4: Before disabling the pool cast Hardiness. Wear the BMU. Blast away Melissan with 5 Greater Whirlwind (no reason to hold back anything, this is the end).
(wearing Human Skin Armor as for the majority of the game)
And finally let's consider what could we destroy during the entire saga:
- The Iron Throne: destroyed
- Baldur's Gate: destabilized
- Sarevok's cult (including a doppelganger invasion): destroyed
- Shadow Thieves: destroyed
- rival organisation of the Shadow Thieves: destroyed
- Anomen: destroyed
- Keldorn: destroyed
- Viconia: burned to death for we didn't rescue her = destroyed
- Jan Jansen: imprisoned, and probably died from captivity because we didn't free him = destroyed
- Minsc and Jaheira: likely the roof collapsed on them while being caged because we didn't rescue them = destroyed
- Yoshimo: destroyed
- Mazzy Fentan: left in a dungeon, imprisoned - starved to death because we didn't help her = destroyed
- Valygar: destroyed
- (Shadow) Druid sect near Trademeet: destroyed
- Spellhold: pretty much destroyed
- pirate rule in town next to Spellhold (Brynnlaw): destroyed
- Shaugain city: for keeping a mad king who exiles and executes his nation = destroyed. Alternatively we could dethrone him and place a mad prince on the throne who'd attack BOTH drows, illithids, and practically anyone you can think of = destroyed. Heck, this city/race is pretty much self-destroys either way...
- Underdark draw ambush against the surfacers: destroyed (because we killed their leaders, prevented contract with a demon etc.)
- if playing with warrior, the noble family of Roenals: destroyed
- all other Baalspawn: destroyed
- Baal, lord of murder: destroyed
- all (ex-)cultmember of Baal: destroyed
- The Throne of Baal: destroyed
