Sorry for the late review, but here we go:

Thy sins
1. Full attack speed runes
2. Boots start
3. Teleport for an ADC
4. Cheatsheet is a mess
5. Masteries make no sense (go 21-9-0 instead)
6. All content and explanations in spoilers
7. Chapter order makes no sense
8. Build explanations are minimal
9. Runaan's hurricane
10. Only 1 defensive item mentioned

Thy blessing
1. Except for the overdose of spoilers and the bad chapter order, good use of structure and coding
2. Bonus: Sort of matchups and synergies
3. C2V

Result: Path of the Infidel
There is just too much wrong. Both build and guide suffer from a lot of mistakes. Get your information out of those spoilers, fix your build, make explanations more complete etc.

Here is some useful information that might help you a lot with your guide.

Good luck

"Mid-game winning build": Rush trinity force. Sure, okay.
"Mid-game losing build": Still rush Trinity force. I don't see why you'd get Trinity force if you're losing lane in the first place.

The stats it gives are minimal for the price and scattered all over the place. If I'm playing an ADC, I'm just going to rush BT, or Bork in some cases, and heavily out DPS you since you don't have barrier or any decent items. Sure the Sheen is going to make you hit a little harder, but you have no life steal compared to any ADC with a BT.

Secondly, BorK is way more important than BT. AS+AD are your key stats since that gives you stronger, and faster passive procs. Trust me, I've played a lot of AD Thresh.

No huge armor pen means you're going to hit like a limp noodle, even with the crits.

And, if you're going to tell me, "I list it as a situational item." I'm just going to stop you right there since, as an AD Carry, you NEED the armor pen to stay relevant.

Don't write paragraphs in your notes for items. They're supposed to be notes, not the lesson re-written.

Please look at Maw of Malmortius, Guardian Angel and Frozen Mallet in the Situational Item build. If you look at Thresh's Damnation passive, he builds AP as he collects souls, as well as the AP in his Trinity Force. As for the attack speed runes, they are my personal rune page, if you read the guide, there are other suggestions as well. I've yet to read your argument on that.

On another note, I suggest you get out of Bronze V (http://www.lolking.net/summoner/na/41815718) and improve your own guides before you downvote one that you haven't read thoroughly.

No defensive items at all.
Spellsword in masteries on an ADC.
Attack speed runes to help with farming and crit...cant argue with that.... Oh wait.

My bad, I've been saving my edits, but I didn't realize I had to press publish again to apply them. >.> First guide.

There is a lot of math here oh man. I'm not sure how to explain it, but for now I'm just saying it's in situation because if their team doesn't have enough HP,it won't deal efficient damage, and the bonus damage is only added on top of these other sources of damage. So I put both of them in situational items, so you guys could decide, I don't want to be too rigid and say, "THIS is how you should build", but rather give suggestions so you can see what works for ya. Flexibility is essential in game, one build can't win every game :/

After using any skill, your next autoattack will deal damage from four sources, if you include Blade of the Ruined King:
1) Auto Attack Damage (Can Crit)
2) Flay Passive Damage (Cannot Crit)
3) Trinity Force's Spellblade (Cannot Crit)
4) Blade of the Ruined King's passive (Cannot Crit)

For simplicity's sake, we'll say Thresh is Level 18 with no masteries/runes and has 86 Base Attack Damage, along with the 30 Attack Damage from Trinity Force and 25 Attack Damage from Blade of the Ruined King and an Infinity Edge with 70 Attack Damage for a total of 211 Attack Damage. Let's say he has 50 souls.


Scenario #1 (BotRK rather than BT)

So our damage is calculated like so:
1) (Critical Strike) 250% x 211 Attack Damage = 527.5 Physical Attack Damage +
2) (No Critical) 50 Souls + 200% (211 Attack Damage) = 472 Magic Attack Damage +
3) (No Critical) 200% x 211 Attack Damage = 422 Physical Attack Damage +
4) (No Critical) 5% x (Enemy Health : 3000HP) = 150 Physical Attack Damage

For a total of ~1100 Physical Attack Damage and 472 Magic Damage
or 1572 Damage in total. It sounds about right, I've seen some ADC/APC's health bars go from 90% to 15% as a result of that one autoattack.


However if we substitute a Bloodthirster in, instead of a Blade of the Ruined King, we get:
Physical Attack Damage :
Initial 211
-25 (Taking out Blade of the Ruined King)
+100 (Adding Bloodthirster with full stacks)
Final 286


Scenario #2 (BT rather than BotRK)

So we have 286 AD and only three sources of damage on our first autoattack:
1) (Critical Strike) 250% x 286 Attack Damage = 715 Physical Attack Damage +
2) (No Critical) 50 Souls + 200% (286 Attack Damage) = 572 Magic Attack Damage +
3) (No Critical) 200% x 211 Attack Damage = 422 Physical Attack Damage

For a total of ~1137 Physical Damage and 572 Magic Attack Damage, or a total of
1709 Damage.


Of course I didn't include Armor/Magic Penetration or Armor/Magic Resist, but they are both proportional regardless of whether you have the Bloodthirster build or the Blade of the Ruined King build. For example if resistances decreased the damage in Scenario #1 by 25%, it would still reduce the damage Scenario #2 by 25%, and it would still be higher (the damage) in Scenario #2.

In Scenario #1 with the Blade of the Ruined King, I gave the enemy 3000HP for the passive damage to calculate, however, I'm sure most ADCs don't even have this much HP, so it would do even less damage.

I guess that's my reasoning:

- Trinity Force
- Bloodthirster
- Infinity Edge

= 1137 Physical Damage
= 572 Magic Damage
= 1709 Damage


- Trinity Force
- Blade of the Ruined King at 3000 HP
- Infinity Edge

= 1100 Physical Damage
= 472 Magic Damage
= 1572 Damage

So with a 3000HP Opponent Bloodthirster > Blade of the Ruined King
Blade of the Ruined King Scales with HP, so lower HP = lower damage.

Of course this is only in terms of the first hit, the Blade of the Ruined King is better over time as it has it's +40% Attack Speed as well as it's passive, however I'm focusing on trying to kill the enemy as fast as possible, so I made my guide with the intention of a DPS/Burst Hybrid Thresh. This setup usually kills the enemy squishies in 2 hits, if feel if it takes longer than that, then I may as well end up dead as the enemy team reinforces their teammate.

Thanks for reading!

Blade of the Ruined King on AD Thresh is by no means a situational item. It is keynote and should default to being your lifesteal item over Bloodthirster every time.

If you doubt that, consider Flay's passive damage stack as well as BotRK's passive, and calculate the potential on-hit for it if Flay is fully stacked. That becomes nearly all of your damage even if the rest of your build turns out like junk. Change that and your guide becomes substantially more credible.

Hehe my bad, I own him now, at the time I didn't. After playing him free week like everyday, I fell in love with ADC Thresh. :D

You don't own the champ and you're writing a guide about him.
What.
