Ability Power Tryndamere relies on his Q and E abilities for this build to work.

- Hextech Gunblade gives Tryndamere some AD and AP so he can push a lane with a a stronger E than from just extra AD. The life-steal and spell vamp provide Tryndamere with means to maintain health as well as the bonus healing the Q does from ability power. The Gunblade's Active does good amounts of damage with the other items in the build.

- Ionian Boots of Lucidity is just used to make Tryndamere's abilities more readily available because most of his damage in an AP build comes from his E and he survives with his Q.

- Lich Bane gives a lot of damage to Tryndamere's first basic attack after as spell, which is useful considering how his W and E can be used to get the an enemy champion. When the full build is made, this extra damage is very substantial.

- Malady makes building Ability Power useful to basic attacks through the extra magic damage, based off of AP, that it applies. The attack speed is helpful in using the passive.

- Nashor's Tooth adds AP, give a faster attack speed, and the important Cooldown Reduction.

- Rabadon's Cap gives the final AP that sets the effectiveness of AP for Tryndamere on a high level.
*Can be substituted for Deathfire Grasp for its Active that deal 15% damage.

Masteries:
-The most important masteries are Weapon Expertise, Sunder, and Spellsword. The armor penetration is for the E, because, even though most of its damage is coming from AP, it deals physical damage. Spellsword increases the effectiveness of AP on basic attacks, and with Malady, Tryndameres basic attacks do 15% AP.
