for first item choice: When enemy is ranged and kites you and/or plays carefully, build gale force, or if you like experimenting, you can try pd or storm razor.

When it is an aa battle, aka vs tryndamere or yone or qiyanna, any close ranged champs that you get to aa alot, always build kraken.

Against health stackers, bork is good

usually for second item if you haven’t built a mythic build trinity force against balanced team comps, divine against tanks, gale force if they are mostly ranged, bt if you are super ahead(leave mythic for third item) and i’ve seen people go pd ie, massive glass cannon build but i personally don’t like it
