you misinterpreted the ap scale on heal.

read carefully.

glyph of potency is meh.

WRong on AP explanation.

Jake you are wrong on several levels. AP bonus to healing is flat and applied independent of stacks. Therefore at level 1 you heal for 80+15=95 not 200. Same goes for trinity force simply with your runes and trinity it heals for an extra 60 per Q not per stack. So at level 18 you heal 460 not 960 like you propose. Also trinity force, the 150% base attack is applied to only 80 of your damage despite your crit. So simply you are adding 40 damage crit or not period.

Trinity Force

FAIL:
4.Trinity Force- increases movement speed to 502 (very close to max possible move speed) increases critical strike chance, and give tryndamere a slow on hit which helps chase. finally the 150% damage buff after casting a spell is incredible stacked with your crit damage.

I think Trinity Force isnot required for Tryndamere.Item such as Sheen and Phang are not required.Sheen cost 1260 and Phang cost 1315 that is cca 2575.For That money you must buy or begin to make second Infity edge or The Black Cleaver-(+55 Attack Damage
+30% Attack Speed UNIQUE Passive: Physical attacks reduce your target's Armor by 15 for 5 seconds (maximum 3 stacks). This item have good passive "reduce your target's Armor by 15 for 5 seconds".Tryndamere need this for better demage and faster kill.

And for start i use Avarice Blade(+12% Critical Strike Passive: Gain an additional 5 Gold every 10 seconds and Sword of the Occult (+10 Attack Damage UNIQUE Passive: Your champion gains 5 damage per stack, receiving 2 stacks for a kill or 1 stack for an assist. This effect can stack 20 times; you lose a third of your stacks if you die. At 20 stacks, your champion's movement speed is increased 15%.)

Lol, your masteries page. Archaic knowledge has helped me get multiple kills with my spinning slash.. Also, Trinity force on Tryn is another LOL, it's not needed in any aspect of the character's play style. You're better off with another Phantom Dancer. Also Last whisperer is the only counter to a thornmail tank. There's a bug with thornmail as it returns true damage and not reduced damaged. Why would you not want the extra reduction to armor? 10 armor on a squishy is a big difference in damage.. ignite or ghost masteries are just as helpful while ignite is down you get 15 extra healing from each bloodlust stack.

Here's the math. Say you can deal 1,000 damage in crit. But their high armor makes you deal about 300 crit damage and you life steal for about 25% of what you do in damage. The thornmail will in return deal 300 magic damage back to you since you're max capability is 1000 damage even if you can't hit that high on the champ. So you heal for about 60 hp per hit but lose 240 hp per hit if they just sit there and they have 26% more hp than you, you will end up killing yourself if you don't ult or use your bloodlust stack.

The best route is a IE, 2 PD, 2BT and a last whisperer or another BT. with 410 movement speed with just two phantom dancers and no boots, there's no need to get more since your slow does it's job, regardless if you get slowed or stunned what good will 100 more movement speed do for you? When you get trade in the speed for more damage to spin in slow and burst damage them in 2 to 3 hits with a 1.8+ attack speed.

75% life steal, 500 damage, 290% crit damage, 1.8+ attack speed 410 movement speed, can't go wrong there..

Good try with the build, also ignite for Tryn works fine as you can cast it on those who run away or for kill steals it's gotten me a few kills with those who've gotten away past their towers while my ult is down.

Rune page we'll glyphs are interchangeable, imo ap or cooldown works just fine no issues with your rune page at all.

why sacrifice an ability to heal for little spin? If you get into a fight the stacking bloodlusts in return to more damage and if your going to die as Tryn you're going to die, your spin is nothing when snare and stun are your main issues. I main with Tryndamere and have over 300 games with him. I've tested tons of different builds and ideas as well as laning partners.

+1 Forgot to vote :)

This is almost the same build I use. I dont have the runes yet and it works wonders.

Tho your calculations for the crit damage are off a little, you also gain 10% crit damage from your masteries and that is not included in your finishing total(with or without the bloodlust stacks)

You should add some visual pictures to the guide, it will become more popular like someone said before me.

also trinity is very usefull because of the 30 ap. 30 ap heals you for 360 extra health with bloodlust.

isnt a problem with tryn he is one of the best farmers and its not like your weak till late game its still a great build for all game

but very expensive build..2 4k items :S

yes there is a cooldown on Trynity, its the slow i feel is needed, along with the 502 movespeed and additional crit. it just caps out everything
