The new DMG likewise has a big table for figuring out how many rolls would succeed given a target number and number of rolls.

I have two approaches I prefer these days:

1. The damage pool. Instead of tracking individual damage, you pool damage in a single tally and remove the last monster hit when it crosses the HP of a monster. Add up all the damage and remove a bunch of monsters with an area attack.

2. Group up sets of monsters into four groups and then roll once for each group. If sixteen skeletons have to save versus a turn undead. Group them into four groups of four and roll four times.

We have a handful of ideas like this in Forge of Foes and the Lazy DMs Companion and released them under a CC license here:

The Black Flag SRD also has some simpler spellcaster NPCs.

I really didn’t know anything about Lemmmy. Things are moving fast. I did mention Mastodon, blogs, podcasts, and rss feeds.
