Hi, just wanted to share this.
Based on some advice about sorcerer spell picks here in the forum, I finally got around to trying the Grease spell with my IWD sorcerer.
Good grief, Grease is good.
I was such a hard sell on this spell, I've spent since 1998 on the EE games without ever trying it, always reading the spell description and saying "meh - I'll pass".
Grease has got to be one of the most under-used and underappreciated spells in the game.
Here's why it's so good: Even if creatures within its AoE make their save against falling down, they are still under the effects of the spell's slow movement.
And, that slow movement is *really, really, really* slow. As in, the creatures within the Grease field might as well be Entangled for all intents and purposes.
I think now that Grease is even better than Entangle, because even if the enemies choose to stand there and cast spells or use ranged attacks, which they can do freely while Entangled, with a Grease spell, they still have to keep saving every round or fall down, interrupting spells or taking out a whole round's worth of ranged attacks.
I look forward to seeing if this spell is as effective in Baldur's Gate as it is in Icewind Dale. If so, I think that Grease is going to become a staple of my first level spell repertoire. I'm starting to think that Alveus Malcanter himself could become useful to a party using only the Grease spell.
EDIT: Apparently I was wrong about Grease causing "fall down" on a failed save. A successful save is supposed to completely negate the effects of the spell. But, my experience with the spell in practice is that it is much, much more effective than the spell description would lead one to believe. I assumed the "fall down" effect based on observed behavior in the game. I was testing against Icewind Dale lizardmen, who may just have very lousy saves. I'll keep testing. Judging by the amount of agreement I got based on this apparently mistaken post, a lot of other people have found that the Grease spell is much more effective than advertised, for whatever reason.
