Zyra is one of the best offensive supports to carry a League of Legends solo queue game. She punishes immobile champions and is a nuisance to deal with, even if she is behind. She scales well with Liandry’s Torment and Rylai’s Crystal Scepter, making her difficult to deal with as a melee champion.
Runes
Sorcery
Arcane Comet: Arcane Comet is the best offensive keystone for Zyra because it is easy to activate and deals a lot of damage early on. Your plants can enable this keystone easily, and the slow from your kit will ensure that the Arcane Comets will land even if enemies try to dodge it.
Manaflow Band: This rune will solve all your mana problem since you won’t be purchasing any mana or mana regeneration items. It is very easy to stack, ensuring you get out of the laning phase with an additional 250 mana.
Transcendence: Transcendence is an overall great rune to have to spam abilities more often.
Scorch: Scorch is an early-game rune to enhance your poking potential.
Domination
Taste of Blood: Taste of Blood is a simple sustain rune. It gives you some health back from short trades during the laning phase. You want all the sustain you can get to survive the early game.
Relentless Hunter: Relentless Hunter’s movement speed bonus is great for Zyra since you need to have equal movement speed to the opposing champions who will rush mobility boots.
Bonuses: +9 adaptive force, +9 adaptive force, +6 armor
Starting items
Spellthief’s Edge
This is an offensive ability power-oriented support item. You will be able to farm early gold with it while also increasing your poke potential. It is upgraded for free as the game goes on and is a great investment for any ability power champion.
Health Potion
During the farming phase, you are most likely going to take damage from enemy champions. Health potions heal back 150 health over 15 seconds and will give you extra time before having to base.
Core items
Sorcerer’s Shoes
Sorcerer’s Shoes is a straightforward choice for boots with magic penetration to increase your damage potential.
Liandry’s Torment
The anti-tank item, Liandry’s is a must-have on Zyra in most games. It grants you ability power, health, a passive to increase your overall damage while in combat, and a great damage-over-time effect that is increased against champions affected by movement impairing effects. While its effect is not ideal against squishy champions, it’s a requirement against tanks if you want a shot at killing them.
Control Ward
Always buy two of these bad boys when you can. While the Oracle Lens has a cooldown and can be countered by the enemy team with wards after it expires, the Control Ward remains in place and ensures that no vision is being allowed in the area you’re using it. As a support, you want to make sure that you have one on the map at all times and one in your inventory for backup, especially if you intend to do objectives.
