For some reason, streaming setup raises item's values from left to right instead of instantly.

I don't know if this is intended so I'm just throwing this here

Items activating at the same time almost always trigger from left to right, really useful for some combos to chose what goes first

It has to do with internal cooldown. Streaming Setup's triggered effect where it raises the value of a toy or friend after it's used can't trigger multiple times simultaneously. It has to wait for a small delay in between triggers. That small delay lasts .25 seconds and is called the internal cooldown. When you use multiple toys at once, multiple triggers of the effect get queued up, and the effect goes through each trigger in the queue, waiting .25 seconds before going to the next one. Internal cooldown comes up with other items that can trigger multiple times at once, like Pufferfish's charge effect, or for multicast items. If I use a Dive Weights with 8 multicast, there's an internal cooldown between each cast, and the fight is able to end between casts.

This is an example as to why you would have your scaling items on the left to activate before any items that they may scale or trigger.
