I had a suspicion that my first SCS game would not also serve as a no-reload/minimal reload game. That suspicion has been confirmed (repeatedly...)
Last night's encounter with the Rakshasa in the druid grove proved an excellent case in point. I remember that being a tough fight in the past, but this time was insane. My party was doing zilch damage with +2 and +3 weapons, while they were getting hammered like a loose nail with AOE spells. I then noticed that they had cast protection from magical weapons, and as it happened, a few of my party had non-magical weapons. (Including, amazingly, a regular old club)
They were STILL doing no damage. None. They were all unhurt after several rounds, while, as usual, my party was getting pounded like a cheap steak. This was despite softening them up with greater malison and lower resistance. So, I reloaded and tried a different tactic.
I cast invisibility on Isra, then sent Imoen and Branwen into the corner where they couldn't be seen and had them unload a few skeleton warriors. I had Sirene talk to/agro the "witch", and then everyone but Isra left. Thankfully, no one cast invisibility purge, so she was able to direct the skeleton warriors unseen to "milk" the Rakshasa's spell books with no harm done. (though they did wipe the floor with them in the process)
Eventually, I had each party member pop in, get them to cast a few spells, then pop out before they could land. After a few rounds of this, they were depleted and down to straight up melee fighting. Now we were getting somewhere. Both parties clearly had good armor, as neither side was doing much damage. However, with enough greater malisons, Sirene finally got in some good hits on one of them.
The rest of the fight more or less involved Isra and a skeleton warrior herding the bad guys around so that Branwen, Imoen, Jaheira, and Sirene could wail on them one at a time. It took many, many rounds, but they finally whittled them all down. Eilrie, the party sorcerer, was down to foul language by the time it was over.
Clearly, something changed, because I don't recall that fight ever being that insane in the past. It was a fun play, though, and it definitely required a change in tactics.
