Taliyah has a lot of ganking pressure early. Try to stand behind minions to avoid being hit by her
when she engages since they deal a significant amount of damage in the early game.
Try to constantly punish Taliyah whenever she uses her
since this is her only crowd control. Seek her out and engage onto her when she has used her
on the monster camp.
Taliyah will tend to gank as much as possible to get ahead. Reduce her carry potential and experience gain by stealing away her camps when she shoes on another side of the map.
Try to get some magic resist against Taliyah since she does deal significant damage when she has some items. Always avoid being in an open spot. Standing behind minions is ideal if she tries to gank your lane.
When running away from Taliyah, make sure not to be standing by the wall since her Passive grants her movement speed whenever she is near one.
Look at the circles Taliyah casts on the ground. If she's standing on them she can only launch one rock at a time. Fighting her in her circles reduces her damage output.
Taliyah begins to do some serious damage when she gets Seraph's Embrace since this gives her AP, mana and a unique Passive shield. Avoid fighting her when low since this shield will most likely save her!
Taliyah has a good ganking potential since her
casts a wall that blocks entrances and allows her to slide on it. Constantly have vision on her since she can easily be roaming!
Taliyah becomes an issue when she has Zhonya Hourglass since this gives her armor and the unique ability of becoming invincible. Don't underestimate her since she does some serious damage and can prevent an all in quite easily.
