Was the party wizard a drow? I always associate both the web spell and the darkness spell with the drow race ("spider, spider, spider!"), to such an extent that I normally expect wizards of other races to learn other spells instead.

It is your right as a DM to make that call, especially if it helps your table's verisimilitude. But really if you can make an attack with a bow or sword, then you can cast spells. Heck you can use a sling!First off, i think you are completely justified in your call. It is logical, you're the DM and it's a snap judgement decision. Personally, due to the way the restrained condition is worded, attacking and Dexterity checks ARE possible, just hampered. As such, i would have allowed the spellcasting but with a considerable chance of failure, maybe 50%.
