The choice of Bel'Veth in the support position is highly viable and aggressive, rarely losing skirmishes in the bot lane. Furthermore, her gameplay is relatively straightforward. She enjoys remarkable mobility, with four dashes available in her Q ability, offers a robust crowd control with her W, and brings an effective damage mitigator with her E. Her R ability makes her resilient in teamfights, providing significant survival potential. Bel'Veth can impact the game in various ways, including the ability to secure Heralds and pressure side lanes, facilitating tower takedowns. Thus, she can fulfill the role of a support capable of split-pushing.

Bel Veth's support strategy revolves around aggressive engagement. She uses her Q ability to approach enemies, her W to apply crowd control, and her E to reduce incoming damage. In situations requiring retreat, she can use her Q again.

When Bel Veth chooses the Press the Attack rune, the strategy is to trigger the rune to amplify her allies' damage output. This approach aims to enhance the damage dealt to targets affected by the rune, combining it with the amplification build composed of items such as Even Shroud, Zeke's Convergence, Imperial Mandate, and Abyssal Mask. This combination allows her allies to inflict substantial damage. However, it's important to remember that this build won't make her as resilient, so caution is necessary. The use of her E ability is crucial for mitigating enemy combos, like those from Lux or Zed, serving as an ace up her sleeve for survival.

If you are playing with the Glacial Augment rune, try to land your W for successful trades. If you miss it, you have to retreat and wait until the W is available again. This rune can make a significant difference in teamfights as it inflicts substantial area slow. When combined with the Font of Life rune, it provides additional sustain to your team.

Try to rush level 6 as soon as possible by making efficient recalls to secure the Rift Herald early. If you manage to secure the first Rift Herald, apply pressure to a lane with your passive larvae. Look for opportunities to secure kills to extend their duration, and make the most of your time by pressuring lanes with this ultimate passive.

Bel'Veth's E mitigates 70% of damage, so draw focus onto yourself, making them expend their skills, thus creating an opportunity for your team to fight with a spell advantage.

I hope that players find success when applying this strategy with Bel Veth as a support. Good luck in your matches and make the most of this support champion's potential! If you need more tips or information in the future, don't hesitate to come back. Enjoy your games!
