Gwen can deal a lot of damage very quickly with a fully stacked Q. Look for trades when you have max stacks.
Her Ultimate R can be recast multiple times. It also offers her a heal which helps her in 1v1 fights.
Your W is a great tool that can stop incoming abilities such as Thresh Q or Blitzcrank Q. Although it doesn’t protect your allies, you can put yourself in between you and the enemy so your ally doesn’t get CC’d.
Gwen is difficult to play into ranged champions. They can constantly harass and bully her which will make it difficult for her to survive the early game.
Your Q will only be as impactful as you make it. If you use your Q without multiple stacks, the damage will be futile.
Her W doesn’t block tower shots, but it does increase her defensive stats. With this in mind, always think twice before committing to tower dives.

In the first few levels, play safe and avoid committing to any trades. Your very early game is rather weak, so you’ll probably lose trades versus an aggressive laner.
Once your Passive is stacked, you can look for fights with the enemy. Looking for skirmishes when your Passive is stacked will increase your damage output and increase your chances of killing the enemy.
Focus on good wave management and going for favourable trades. If you are constantly pushing, you will not be able to get kills as your W doesn’t protect you against tower shots.

When no team fights are occurring, go in a side lane and look to split push. This way you will continue to earn gold and XP which will help you get to your next major power spike.
Gwen is a strong 1v1 champion- especially if she was able to get an early lead. Look to apply pressure and fight whoever on the enemy team tries to stop you.
Continue to play around your Passive and your Q in mid-game fights: especially in 1v1 skirmishes. You will miss out on a lot of damage if you don’t play around it.
In the late game, stay with your team. Avoid moving too far away from them as the enemy may force a fight while you’re gone.
Focus the nearest enemy champion in team fights. Even with your W, you are still squishy and vulnerable to the enemy backline. Focus the same champion as the one your allies are focusing.
You can dish out a ton of damage in late game team fights with your empowered Q damage. Ensure you’re auto-attacking as much as you can to increase your Q damage.
Gwen isn't powerful early on, so she must use her Q to its full potential in the lane. It will give her a lot of sustain and damage, but she will need to invest some time stacking it.
Gwen's level 6 is a significant powerspike for her. She can quickly run down enemies now as the amount of healing she gets from the damage output of the ability is quite potent. She should be winning a duel with ease from now on.
Getting the first component will surely help Gwen's laning phase a lot. Her damage output will increase, which will let her go for short burst trades on her enemy with her E and Q. She can later use her W to escape.
Gwen is perfect during this stage as team fights frequently occur, which gives her multiple targets to land her abilities on. As a result, she will dish out tons of damage while healing up during a major fight.
Gwen will get a massive boost to her fighting power at level 11 due to her Ultimate R now having two points. It is highly beneficial for her team as that ability does a lot of damage and can completely change the tide of a fight.
At level nine, Gwen will be able to max out her Q. That ability is her paramount damage ability, and it will start dishing out a lot of damage from now. As a result, her enemies will have a hard time dealing with her now.
Her kill pressure increases during this phase of the game due to her maxed out Ultimate R. As a result, she will easily win any duel, provided she didn't fall drastically behind during the early or mid-game.
Gwen excels during team fights as she can dish out a lot of damage, especially when fighting around clumped areas. Her W allows her to mitigate a lot of damage, and her E lets her reposition quite quickly.
Gwen does deceptively high amounts of damage during this phase of the game due to her items. She will also have maxed out most of her abilities. She can spam her abilities, which directly translates into more damage and healing for her.
