Best Arum Build, Rune Page & Guide for 2026

Arum is a tanky support hero in Arena of Valor. This hero’s ban rate in ranked matches is extremely high because of her incredibly annoying hard-crowd-control kit.

• Only go full magic on Arum if you’re confident your mechanical skill is clearly better than your opponent’s, otherwise it’s very risky, since this isn’t a mobile hero — full-tank, unkillable Arum is generally the safer choice in ranked.
• Build your support item first depending on the situation of each match.
• Once you have extra gold late game, rotate between Amulet of Longevity , Blade of Eternity , Rock Shield and Death Sickle .
• If facing strong magic damage, build Medallion of Troy instead of Mail of Pain .

At the start of the match, Arum is fairly tanky and has decent damage, so play proactively, attacking and trading skills with your opponent continuously.

Use Skill 1 Lion Tamer to poke the enemy and stack spirits; once you have 3 spirits, use Skill 2 Uncaged to strike your opponent for big damage and an extremely annoying effect.

You can also stack spirits and use them to trigger healing from your passive Ravenous Beasts to hold your lane better.

If there’s an opening, take advantage of Skill 2’s Uncaged long range to harass the enemy jungle.

Arum ‘s job in the mid game is to keep following and protecting the AD, or if the AD is already tanky enough or has another support, you can follow your assassin to coordinate ganks.

Always keep Skill 3 Snare and Flicker ready to suddenly hard-suppress the enemy’s core damage dealer and send them to the kill feed.

Remember that while using Skill 3 Snare to suppress an enemy, any damage Arum takes is transferred to the suppressed target, so plan carefully to turn the enemy’s turret hits or attacks into damage against themselves.

The late game is when Arum is extremely tanky with a full-tank build, so lead the charge for your team when opening fights.

Always stick with your team during this phase and act as a shield to create space for your allies to fight.

Use Skill 2 Uncaged for wide-area damage and crowd control, and Skill 3 Snare to suppress an assassin threatening your AD or to pin down the enemy’s core damage dealer to secure the win in the fight.
