Boots start never ceases to make me cringe. People pls, it sucks

If Rylai's Crystal Scepter procs with Stormbringer. I would replace it with Frozen Mallet. It would be like an multi-target-auto-attack slow. You'll also deal more overall damage. Just a suggestion though. Tell me what you think.

I just wanted to understand the ups and downs between the 2 and why phreak choose to use rylais instead of frozen mallet

lets analyze how each item works, by the way, since I dont have enough ip to buy the champion, i only have information from the wiki page to go on for ap ratios, so if I have the wrong information plz correct me so I can understand him better

now for benefits of the passive, frozen mallet will give more benefits since it provides more hp thus more healing per second and thats about it for that

for rolling thunder, since theres ap or ad ratio (according to the wiki page) and since the ability does damage on next attack and is a single target, theres no real benefits between the 2 items

for frenzy, you get better damage from frozen mallet since it adds 140 damage while with rylai's you only get 100 bonus damage. but with rylai's your able to cast it at a slight range thus able to catch up to the enemy, but with frozen mallet you get the slowing effect while attacking and thus helps you stick to the enemy.

for majestic roar, it already has a huge slow to it thus neither of the items are useful for it's slowing effect, but with rylais your increasing the damage of the aoe by 60% of your AP. with frozen mallet you can at least again stick to your enemy.

for thunder claw, im unsure but I feel like rylai's will only proc the reduced aoe version of the slow but will also proc it on multiple enemies. and since this will only happen on attack, thus frozen mallet will provide more slow but only to a single target

so after analyzing, it seems to me that against single enemy frozen mallet is far superior but rylai's is better if you plan on being aoe. but over all I think frozen mallet is a better choice

Need I explain? Good coding, well detailed, lots of effort. The only flaw I see is that its way too long. Probably add some unnecessary points into a spoiler.

Nice build, this is nicely put together with a good amount of bbcode. You have explained everything nicely, i like that you showed all the different defensive options. My only thing is i don't know if you have the items in purchase order, that needs explained. If it is in purchase order, i would put Frozen Mallet before Randuin's Omen. Well gj on this build and keep it up!
