JB2A_DnD5e VS foundry-user-latency

JB2A has a lot of animated spell effects. Not so much animated things though. You can get some of them for free, but I think most are available through Patreon.

I would keep my eye on Advanced Spell Effects by Vauryx. He does some pretty amazing things in setting up some of these more mechanically complicated spells to be fully functional. He recently added a couple Wall spells to the repertoire and while Wall of Light isn't in there yet he has said that more are on the way now that he has the foundations of wall mechanics figured out. He has a couple dedicated channels in the JB2A Discord where he posts updates and whatnot.

What you can do is go to their Github at https://github.com/Jules-Bens-Aa/JB2A_DnD5e and then download the zip file. All of the animations are in the zip and they are simply .webm files that you can import as tiles in any system. (Or assign as token art, etc.)

User Latency v1.3.8 Bugs URL

I own the library Ping Logger which just adds in the latency of all the current users next to their name. I find it incredibly helpful and useful, especially when people get hiccups. If you see someone spike to 2000 or something, you can expect to just wait for them to come back.

You can check if the lag is network related with https://foundryvtt.com/packages/ping-logger

We had a similar thing occur in our Starfinder game, though the symptoms were more widespread and affected everyone. The slowdown affected everyone: simply moving across the canvas took ages, and actions took very long to show up in the chat log. This would also show up in the Ping Logger output as a very high ping (12k ping, which is 12 seconds, the time it took any one of our computers to querry the host's computer).

I would advise trying self-hosting first and if it works well for you then you're good to go. If you have lag, then perhaps look into a hosting platform. I'd also advise getting the Ping Logger mod. It shows the ping speed for each user next to their name. That way you can see if any lag is user specific or if all users are having issues.
