@Donutknol Thanks for the advice!

@zxcllvbyjuj Of course, everyone has different opinions, I was just trying to help you out a bit with your guide. Good luck with your guide and the coding ^^

@Donutknol
1. Devourer is still very OP as it gives you a Nasus-like power in that your autoattacks scale infinitely into lategame and gives you a bit of magic damage on your list. In reality, It's all up to whatever your choice is. It's just I RECOMMENDED Devourer for the reasons above.
2. Hydra is amazing on Rek'Sai because it gives her a little bit more burst when going in on the enemy ADC/Squishies. I agree with the Triforce but I haven't given my reasons in the items section as this guide is a WIP. The Phage and Sheen is good on Rek'Sai, but I still think that the AP portion of the Triforce is gone to waste unless you actually use the completely useless piece of **** that is her burrowed Q.
3. Okay, I'll look into what other item I can get. I just like it because I feel like I don't want to get a Triforce for the AP and the minimal stats I gain from it. IMO I think Frozen Mallet is a good item but it is in desperate need of an AD buff.
4. The Swiftness boots were an example. Obviously you would adapt your build to whoever is fed on the enemy team and get the right boots. I chose the swiftness for the slow resist and extra movespeed to help in ganks after the minions hit you.
5. Changed.
6. Oh thats fancy. I'll try my best!

A couple of things: First off, devourer is not worth it since its nerfs, warrior is way better. Second, hydra is not very good, on rek'sai, since her q gives her enough AoE to clear camps. Instead, getting triforce is better, because your are a bursty fighter and the phage proc and movement speed helps you with sticking. Also, frozen mallet is just overall a bad item. I get that it looks good because of the slow, AD and health but other items are just far superior in gold effeciency. Third point, swiftness boots aren't good compared to merc treads unless the enemy only has slows, and no stuns, snares, fears, and taunts (you even mentioned rammus as a counter). 2 more things: first off, don't get armor marks. If you want armor get them as seals, because marks give way less armor. And my last point, don't get the utility points. The movement speed and improved recall is inferior to the reduced jungle and champion damage. I know it's a long post but I really hope you appreciate my advice.
