It cuts movement in half, even if the target isn't stuck to the ground, and they can't charge.

The benefits of this spell, aside from not requiring an attack roll to hit, are that being entangled can seriously hurt an enemy's effectiveness. That can be a big benefit as the game goes on, especially if you are specialized in conjuration. The difference is that you can hold the spell for 1 round/level before the spitting happens (it's only got a 15-foot reach), and the save DCs and attempts to get out of the goo are modified to reflect your spell DCs rather than what's standard in the book. A first level conjuration spell, adhesive spittle is basically a magical tanglefoot bag that you spit out for an automatic hit. Out of all the cheese we got to play with in the Advanced Class Guide, this spell remains one of my favorite additions. they just won't end encounters are higher levels the way they can when you're at the start of the campaign. If you're a fan of debuffing spells, then here are a few that you should hang onto no matter your level, because they're always going to be good to have on hand.

With that said, though, there are a few low-level tricks that are worth keeping up your sleeve. after all, they just don't have anything to contribute when you're going up against ancient wizards of obscene powers, or colossal dragons who can smash mountains to dust with a swipe of their tails. Which means a lot of the time that when you start hitting the final arc of the campaign, you can end up never touching your low-level spell slots.

One of the unfortunate facts about magic in Pathfinder is that all too often spells simply don't scale in power along with your character level.
