- When you are killed zyra's passive turns Zyra into her plant form which allows her to fire a projectile skill shot. The thorn deals 99 + (25 × level) true damage to each enemy hit by it. The form lasts 8 seconds and has an estimated range of 1,500. Personally i find this passive to be very useful in securing a kill.

Tips

Be careful of spamming abilities before death. While Zyra is transitioning into her plant form and you're spamming your abilities to try to do damage before dieing her passive tends to go off immediately even when you don't want it to.

- Zyra shoots thorns from the ground, dealing 75 / 115 / 155 / 195 / 235 (+60% per ability power) magic damage to enemies within the area.

Tips

You want to use this in combo with your Grasping Roots and your Rampant Growth for poke and aggressiveness.
When deadly bloom comes into contact with Rampant Growth, a thorn spitter will appear for 10 seconds and deal 26 + (6 × level) + (20% per ability power) magic damage with an attack speed of 0.800.

- (Passive) Grants cooldown reduction: 4 / 8 / 12 / 16 / 20 %

- (Active) Plants a seed that lasts 30 seconds. If an enemy champion steps on a seed, it will be destroyed but you will have vision on them for 2 seconds.

- Zyra periodically stores seeds and she can hold up to 2 seeds at any given time. Zyra cannot plant any more than 4 seeds at a time. Extra plants striking the same target deal 25% less damage.

Tips

When deadly bloom comes into contact with Rampant Growth, a thorn spitter will appear for 10 seconds and deal 26 + (6 × level) + (20% per ability power) magic damage with an attack speed of 0.800.
When Grasping Roots comes into contact with Rampant Growth, a Vine lasher will appear for 10 seconds and deal 26 + (6 × level) + (20% per ability power) magic damage with an attack speed of 0.800.

- Zyra Sends a wave of vines dealing 60 / 95 / 130 / 165 / 200 (+50% per ability power) magic damage and rooting all enemies it comes into contact with for for 0.75 / 1 / 1.25 / 1.5 / 1.75 seconds.

Tips

I use this ability to start an aggressive attack on enemy players if they are successfully rooted.
When Grasping Roots comes into contact with Rampant Growth, a Vine lasher will appear for 10 seconds and deal 26 + (6 × level) + (20% per ability power) magic damage with an attack speed of 0.800.

- Zyra grows a twisted thicket at the targeted location, dealing 180 / 265 / 350 (70% per ability power) and knocking the enemy champions up after 2 seconds. In addition any Vine Lasher or Thorn Spitter in the area of the Stranglethorns effect will be granted an extra 50% attack speed.

Tips

To maximize your damage be sure to have 2-3 active Vine lashers or Thorn spitters.
Any Vine Lasher or Thorn Spitter in the effect will gain 50% attack speed.
Also using this ult in the mist of a team fight could potentially interrupt another champions ultimate causing your team to gain an edge on the other team.

This is an ideal build. If the enemy team goes for early Magic resist to counter my build i change the order of the build or have a teammate build an Abyssal Scepter:

Boots, Health Potionx2, and Mana Potion is my standard opener. i choose boots 3 pots to easily dodge the enemies skill shot and potential early ganks. The 2 health pots also help with the enemy poking you and for any avoided ganks. As for the mana pot this will help keep sustain in your lane without backing while be able to harass.

The Doran's Ringx2 gives you an additional sustain after backing allowing for even more harass with a bit more mana regen and a fairly decent health increase. With the 2 Doran's Ring your looking at a 160hp 30ap 10MP5 at this point you should be able to harass with no mana issue.

Sorcerer's Shoes are Pretty standard AP boots. However i find using Mercury's Treads to be useful against veigar's.

After i have my 3 core early/mid game items i'm looking at how my laning opponent is build or playing. For example in ranked the player's are fairly decent and are about evenly matched i tend to work for my Zhonya's Hourglass first so i can engage in team fights while being safe knowing i have ZHG if the enemy focuses me or i get caught out of position. On the other hand if i'm getting great ganks and i'm well ahead in my lane i tend to work toward a Rabadon's Deathcap then Zhonya's Hourglass after. Personally my positioning is good and i find that ZHG and Rabadon's pointy hat is better than having a Rod of Ages.

That being said after i have ZHG and RDC i work on getting my Rylai's Crystal Scepter starting with the Giant's Belt then coming back later to fully buy it. If your someone who feels Rod of Ages is better to get early then by all means u can get it after ZHG or RDC or even before both. It really depends on your play style.

Here is were things can be very situational. From here you should just about have your boots, ZHG, RDC, 1 ring and (RCS or RoA). Here we look at the enemy team. We should start to see Magic resist being a common thing on the enemies' build so personally i would go void staff but abyssal scepter is also good for now before they nerf the range of it. and the final item of choice i'd go with for bursty opponents is Banshee's Veil. I see alot of other people working with Deathfire Grasp or just having a set that looks like boots,ZHG,RDC,RCS,RoA, and VS, which is also a great and mostly optimal build for sustain, damage, and survivability. But as i said its mostly up to your play style, team composition, and even the opponents' build.

Aggressive - I push my lane using deadly bloom and creating thorn spitters so i can apply pressure to my lane opponent's turret and help my team ganking.

Defensive - This is usually if i had recently been ganked or i am waiting for my jungler to gank mid, I use my thorn spitters to farm for me along with the damage from deadly bloom sometimes if the opposing champion is in there with my creep i throw in some Grasping Roots causing seeds to turn into vine lashers which in turn slow champions by 30% when they attack.
