Thanks for the comment! Reason for Trinity is because the extra damage with sheens passive goes nicely after dragon strike. Add that with your first hit and its a hefty amount of damage on your first hit. Infinity, well i use it because this is a critical hit build, but yeah Its interchangable. Ill try adding some more pictures when I have the time. Again thanks for the comment and would love it if you rated it :D

Excellent guide, could use a tad more detail/pictures (?)

I've voiced my opinion on infinity edge about a million times, but essentially, I don't think it's a good option on Jarvan.

About trinity force: I've never tryed it, nor do I plan to try it, so I don't know how well it syncs with him, but it's pretty damn expensive.
