In URF where people spam skill to kill so a creep farmer is consider weirdo here . with this build you need at least 200 soul for the build to work = creep is better than people life . So in early game you need to go with any champ that have aoe skill to farm creep , other than that , you are F*cked .

the item of this build need to meet break point to work after the wit's end or runaan is finish (with also 200+ soul ), before that you not very strong and people may consider you stupid , cuz that just how this build work . But after that point you can solo very much anyone who get into your atk range , including strong solo champ like trundle . the power after the break point so high that you can actually tank and kill 2 or 3 champ by yourself alone .

after the breaking point said above , you may prefer stand still and auto atk than use Q or E , W can still be use . Use Q and E stop your atk animation and drop your dmg dramatically

this build is very tanky especially against phys , but not immortal + not very mobility , try not to 1 v 5 , you can be stun to death or dmg shock by 5 people

before the break point , you look like a joke . after the break point , you can delete anything with a ridiculous power .

this build begin with support phrase .

After you get guinsoo , you begin farm phrase , best to ignore your team and go farm lane alone then farm the chicken and the stone in the jungle unless they really need you , also don't push high you are still weak . you can still solo dragon with lantern shield .

After break point , you can choose to farm if your team don't need you and also push high , doing so will provoke some one to solo you , you can mostly kill anyone get in your range now unless they are a super feeded trundle or something . if the one come to stop you have long range , just drop lantern shield and go home :V

if your soul is 300+ and 5 item complete , better go with team and help them as you are both the tank and the highest dmg in the team right now , you can even use your adc as bait now that you already cover role : support , tank and carry .

If you really need to understand how this build work , it like this :
1. thresh E have a passive ( but actually 2 ) : the minimum dmg and the maximum dmg for normal atk .
2. Normal adc thresh will aim at the maximum dmg as main , which is effected by soul + item atk x2 ( at max e lv ) . so if you have 5 atk item + 0 soul , you still deal alot of dmg .
3. This build do the opposite , aim at the minimum dmg . So if you have no soul = you have no dmg .
4. The item in this build include 2 atk spd + key point will give you the ability to normal atk at highest spd but they have really bad dmg themself , but you can farm the dmg but gaining soul , each soul give you 1 magic dmg to normal atk ( and you get x3 in URF )
5. The Riftmaker is a weak item by itself unless you can deal alot of dmg yourself ( which you can , by farming soul ) . and if you can deal alot of dmg yourself , the Riftmaker will offer you very much everything heath , vamp , bonus true dmg .

Most core item got buff + key rune buff so ... yeah , live is better now .
