Overview

How to Play Arbiter — TFT Set 17: Space Gods

Arbiter’s of the set are flexible units due to their unique trait of allowing you to pick a Divine Law. This allows players to have unique effects that apply to Arbiters. This trait has 4 units, but only has it as a 3 trait synergy where the Divine Law effects become stronger.

This means that players will have to be on their toes and be able to recognize when they have a strong Divine Law option and are able to play around that synergy.

TFT Arbiter Champions

Leona (1G) - Vanguard

tft set 17 leona

[Link to Champion Page]

Leona is a Vanguard making her the tank option of the quartet. Her ability Shield of Daybreak gives her a (AP) shield for 4 seconds. Leona then bases the current target, dealing (Armor & MR) magic damage and stunning them.

The utility of her stun makes it possible to place her in front of melee carries to stun them and hope that the backline is able to gun down the unit.

Zoe (2G) - Channeler

tft set 17 zoe

[Link to Champion Page]

Zoe is a Channeler which means she gets additional mana from all sources. This makes it easier for her to cast her ability, Paddle Star. Paddle Star fires a star at the current target, dealing (AP) magic damage to the first target hit and secondary (AP) damage to others it passes through.

Once the missile reaches its destination, redirect it to a distant enemy, increasing its speed and repeating the damage. This redirect can occur multiple times. This makes Zoe able to be one the the AP carries of the comp and with the right Divine Law, she might be a rerollable carry!

Diana (3G) - Challenger

tft set 17 diana

[Link to Champion Page]

Diana is a Challenger which gives benefits of team attack speed and bonus attack speed to challengers. On top of this, challenger units are able to dash to their next target. Diana’s Ability Pale Cascade benefits from this in multiple ways.

First, her ability has the passive where attacks deal bonus (AP) magic damage. Her active gives her an (AP) shield and she summons 3 encircling orbs. The orbs deal (AP) magic damage to enemies they pass through, and rotate faster based on her attack speed!

LeBlanc (4G) - Shepherd

tft set 17 leblanc

[Link to Champion Page]

LeBlanc is a 4 gold unit with the ability Fracture Reality. She has a passive where her attacks deal (AP) magic damage rather than (AD) physical damage. For her active, she summons clones that attack alongside LeBlanc for a number of attacks dealing additional damage for her clones.

For their final attack, clones fire a bolt that deals (AP) magic damage. This means that LeBlanc benefits from not only AP, but also attack speed. She is likely to be a Guinsoo’s Rageblade user on top of AP items. The artifact, Statikk Shiv, is probably also one of her best items!

With the right Divine Law, LeBlanc is probably a strong pick! I also would not be surprised if she benefited from a Challenger Spat while being paired with Diana!
