2. You build AP items.
3. You rush Hextech Rocketbelt.

General

1. Playing AP Tryndamere build, your default rush is Hextech Rocketbelt.
2. Adapt to an enemy team. Are they full of tanks, and they rush tons of Magic Resist? You rush Void Staff as #2 or #3 item to counter MR stacking. Their team has champs with lots of healing? Rush Oblivion Orb as #2 item (upgrade to Morellonomicon as 4th or 5th item).
3. Somebody is going after you each fight? Always getting ulted by enemy assassins? Rush Zhonya's Hourglass.

Bloodlust (Q)

1. Keep auto attacking whenever you can to generate Fury. It increases your critical strike chance and can be consumed with Bloodlust (Q) for healing and sustain.
2. Keep Fury high. Avoid spending Q until you really need to heal. It increases your damage/crit and sustain.
3. If you are getting poked hard and you're having trouble safely hitting minions or champions, just use Bloodlust (Q) on cooldown to heal.

Mocking Shout (W)

1. You can use Mocking Shout (W) to detect enemies hiding in the bush or even invisible ones that try to sneak on you, your team or your Nexus!
2. Players tend to instinctively run when you suddenly appear (especially using Spinning Slash (E)) from a bush or fog of war. Use that reaction to your advantage. Use Mocking Shout (W) as they turn away to apply the AoE slow and reduce their attack damage.
3. Maxing Mocking Shout (W) might be very viable strategy against full AD comps!

Spinning Slash (E)

1. Tryndamere auto + E trick: when auto attacking, be very close or even go little further. This way you can AA, then Spinning Slash (E) immediately for auto + E dmg.
2. Spinning Slash (E) + Flash combo. You can use Flash during E animation. To elevate your Tryndamere's game, do it at the very last frame animation. Works in any direction.

Undying Rage (R)

1. Use R as late as possible. This might bait enemies to use cooldowns and makes you stay in fight for longer. Also beware who you are playing against - sometimes you need to anticipate big burst coming your way and you need to use R early or get one shoted.
2. Generally, hold Q during ult. If you need to heal afterwards, make sure to use it after your R ends (unless it is specific situation i.e. you are taking dmg from DoTs or there's flying turret's shot right as your R ends).

Riot

1. Delaying the activation of Undying Rage is a very effective way to make an enemy champion over-commit to trying to kill you.
2. Bloodlust is an excellent way to heal Tryndamere. Try not to let it fade off before you activate it.
3. If the enemy is stacking Armor, try building items like Last Whisper or Youmuu's Ghostblade.
