All major features of the game work:
What does not
The game will occasionally disconnect, and will fail to reconnect, causing major problems for playing.
If playing fullscreen, if the game loses focus (e.g. by Alt-Tab), it can't regain focus.
For PvP games, when the game disconnects, closing and reopening it will reconnect to the game in progress, if not too much time has passed.
For the focus issue, having wine emulate a virtual desktop (in winecfg graphics settings) works around the problem completely.
What was not tested
Real money purchases were not tested.
The game only works with wine-staging.
The game was broken with wine-5.2 through wine-5.7.

Due to Bug 48665, along with other shorter-lived bugs, Runeterra does not start with wine-staging-5.2 through wine-staging-5.7. It looks like it should be back to its crashy-but-working state as of wine-staging-5.8.
