Trendan the level 8 Undead Hunter - FINAL BG 1 Update
When we last heard from Trendan he was working his way through the Cloakwood. His main plan was protection from magic scroll and a few potion buffs, this took out Drassus and pals. Trendan fought all the way to Davaeorn's level, defeating the battle horrors in melee (heroism potion and STR 19 potion), used up ALL his heal potions, then the protection from magic expiried! I had wanted to run all the way here, but didn't remember where the invisibility potions were. He did all the buffs he could and charged Davaoern -- arrows of biting won the day for Trendan yet again, though he did get down to 50% health.
Once in Baldur's gate, did very few battles/quests here. DEX and INT tome were obtained, did the quest for upgraded shield, obtained helm of balduran, and battled the Mountain Maulers. The plan was to draw the enemies to Gorpel Hind, to buy me more time. This worked out great. Now Trendan retires the spider's bane and uses the battle axe +2 almost exclusively.
Time to deal with the iron throne baddies. Used magic protection scroll, potion of mind focusing, potion of fire resistance (in case Trendan throws fireballs around himself), STR 23 potion, and haste and regeneration potion. This destroyed the enemies, taking only a little damage himself. Using the BG 2 engine allows potions being active when the scroll of magic protection is active, what a huge boon.
Trendan was then sent to candlkeep. Scroll of magic protection was again used and the STR 24 potion to bash some crypts in to get the tomes. Only the initial doppleganger and the spiders were fought. Trendan then used an invisibiilty potion to get through the rest of the crypts.
Back in the city of Baldur's Gate, Cythrandria and her goons were defeated primarily with STR 23 potion, potion of absorption, potion of magic protection and greenstone amulet. The potions were still active when the battle was over, so then headed straight to Slythe. Arrows of dispelling made Slythe much less of a threat. Kristin wasn't too much problem, since his potion of magic protection was still active.
Potions were still active, so headed to Duchal, only adding buffs haste, protection from evil, regeneration, and DUHM (putting Trendan's STR to 25). Lia died, but Belt survived. But had to find the dopplegangers, two were hding in the basement.
Scroll of magic protection and invisibiilty potion were used to get through the thieve's maze and skip the Undercity Iron Throne party.
Time for the main event.
Here is a link to the resources I had before the battle, the protection from magic scroll was still active.I did a lot of potion buffs, and moved foward. I fired a shot from Trendan's necklace of missiles and dispelled Sarevok's buffs. A web then came, presumably from Semaj -- so far, so good.
Trendan then backed off, just outside the web, hoping that Sarevok would park himself in the web, he sometimes fails his save. The battle was going well at first, Sarevok near death, but then all of Tredan's buffs get dispelled! Yikes!

I got the whole crew on Trendan. Tazok is meleeing, Semaj casting spells and Angelo is in the mix too! I tried to melee for a few moments, but Trendan's health rapidly decreased to less than 10%, Sarevok refuses to fall! So Trendan used a haste potion, the idea to run and heal etc. However, Angelo came through for Trendan - Angelo slew Sarevok!

In my EasyTutu, it takes a few seconds for Sarevok's death to register, so Trendan ran way so Tazok didn't get a hit...success! Sarevok is dead...
Extremely close call, but glad to make it to BG 2.
