does anyone know the limits to each of the items?

this is from a few years ago so i am not sure if the limits are accurate....

https://www.google.com/?gws_rd=ssl#q=league+of+legends+limit+to+damg

thats the search i used so maybe i used the wrong words but there is nothing since 2012...like im sure we had a lot of updates since 2012 so idk...i was only using riot sites..wiki has a lot of info as well but i want it to be from a riot site so no one can say i got the wrong information haha

so if anyone knows the limit to

crit dmg armor health gold income ap

i think they do not yet cap magic pen or armor pen since health&armor as well as health&magi resist combinations

i think they are debating what to do with gold income as well as crit/dmg

i know i got capped when i tried to max out on crit items since usually you get capped with one clam or one crit attack speed item... i maxed out my crit runes and was still only allowed one max crit item.... i dont think it works with the low crit because it is a waste of space as welll (also why i dont jg with jg items but i think riot recently capped it...T^T rip me)

i dont think they capped dmg yet but at the same time it is also a waste of space anyways so i didnt complain much when its not capped haha i was only complaining when they capped crit and would like to know the exact limit so i can max out dmg ^-^

also i know ap is sometimes capped like when i buy the hat (+100 ap) its usually capped but sometimes it doesnt always cap since when you buys ap items along with mana haha it doesnt cap the mana but it will cap you in ap...idk if that makes sense....but yeah idk i was hoping to understand the limits so i can bulid more troll and tilt the enemy team more [slayer-jinx-catface]

if anyone knows the limits please post any comments or further information is always encouraged please!!! i really enjoy building and i think that is the best part of the game ^-^
