What are some items / actions that affect terrain?

I coded 3 API scripts for modifying the terrain with macros to the commands as token actions on certain NPCs. I have the following so far: Drops caltrops behind them as they move Sets a fire behind them as they move Used a smoke bomb that creates a 3x3 grid square area of smoke What are some other actions that can change the terrain?

mold earth cantrip to create 5' square of difficult terrain? I assume you aren't wanting to get into leveled spells?  If I'm wrong, then there are tons of options there. Edit: Oh, ball bearings.

Create Pit comes to mind.

Edit: Oh, ball bearings. Not looking for spells in particular. Alchemical substances are a good way to do some of the things I want. For instance I just coded an API script that when ran drops puddle images around the character for glue / slippery water / grease for example. I'm playing Pathfinder and this page has been indispensable: <a href="https://www.d20pfsrd.com/equipment/goods-and-services/herbs-oils-other-substances/" rel="nofollow">https://www.d20pfsrd.com/equipment/goods-and-services/herbs-oils-other-substances/</a>

This is the stuff I have so far that can be put down on a square by npcs. All of them have API scripts like "!create-fire &lt;character_id&gt;" and "!create-smoke &lt;character_id&gt;" (Create smoke creates a 3x3 area of smoke so 9 tokens) (Puddle is used for glue) Anyone have any suggestions for other materials or natural, magical or alchemical that I can have NPCs drop behind them as they run off or surround a player with?
