Found a typo / grammar error in the tooltip for Nami's Q.
"Sends a bubble towards a targeted area, dealing  damage to enemies, and stunning them for  seconds."
The second comma (between "enemies" and "and stunning" is extraneous; it is not an independent clause, just a list of two, and so it does not need a comma.
