Raid Shadow Legends: Delver Champion Guide

Delver is an epic spirit affinity champion from the dark elves faction in Raid Shadow Legends. She was buffed back in 2022, making her slightly more useful, with improved damage. However, she still remains as a mid-tier epic, good across the board but not amazing. She can be best used in Arena as a nuker or Clan Boss and Spider teams. Additionally, Delver has a good kit, with a range of useful debuffs her low defense makes it challenging to keep her alive for prolonged periods of time.

Delver Late Game Build Guide

This guide will feature Delver, who is not a very commonly used hero, referred by some as the Vault Guardian. This guide will cover two areas: UNM clan boss and spider 20 runs that can be completed in under 1 minute.


This is a late game guide and Delver will need some specific setups to bring out her true potential as well as booking. Delver have tricky skill but essential debuff on this game: single target weaken 25% and aoe decrease defend 60%. The tricky part is (1) her A2 requires the enemy to a have heal reduction debuff to land weaken debuff but this debuff cannot be resisted (2) her A3 places 50% increase atk 2 turns before attacking and PLACES a 60% decrease def debuff but if there is weaken debuff on enemy. A lot of conditions need to met right?


First thing we need to consider are the masteries. This Delver is built for UNM clan boss. Hence, Warmaster is out priority with a defense mastery retribution as the second choice. For spider runs her AOE skill is also helpful, because warmaster damage proc can do 123k-ish damage to the big spider.

Gear & Stats Build

Artifact sets depend on the team composition you are using Delver in. For example, if you are using her in an unkillable composition for UNM or Arena you might want to choose cruel + speed set or savage+speed. Or if you would like to focus on dungeons you might need accuracy set to get enough accuracy to land that two essential debuff. Lifesteal set for survivability could also be the answer.

Since this build is geared towards UNM clan boss and using unkillable team, 1 speed set and 1 accuracy set is sufficient. The right speed has to be reached maximum dps is a priority along with sufficient accuracy. It will be beneficial to get high atk stat since her base damage is atk, crit rate 100% and as high crit damage as possible.

Recommended Main Stats

  • Glove: Crit Damage % (Preferably) or Crit Rate % (If you cannot achieve 100%)
  • Chest: Atk
  • Boots: Speed
  • Ring: Atk
  • Amulet: Crit Damage
  • Banner: Accuracy

Spider 20

Delver can help with spider 20. The featured team is: Royal Guard (lead and affinity tank), Seer, Delver, Coldheart, and Renegade. Since our champion can place Decrease Defense as long as there is a weaken debuff, Seer can help enable Delver on auto. The Speed tunes for those runs are, 210 CH, 205 Seer, 203 Delver, 165 RG, and 95 Renegade. The turn order is CH A2, Seer A2, Delver A3, RG A2, CH A3, Seer A3, Renegade reduce cooldown.

Why not stag knight or tayrel for Decrease Def? What is good about this composition is that all spiderlings are cleared so they dont get a chance to get a turn. This speeds up the runs. If stag knight or tayrel are used, they cant kill spiderlings with their skills because does not hit as hard as delver does.

UNM clan boss

For Clan Boss Delver can truly shine in a specific unkillable setup. This tune is called Mansalad: 2 Maneaters, Painkeeper, Ma’Shalled, and Delver. Note that without two Maneaters it would be difficult to replicate this success. They are the key element to this composition.

Delver’s skills are tricky but Ma’shalled A3 can place a heal reduction debuff on the clan boss. This comp has a 2:1 ratio of turns starting from turn 7. This means she can can consistently keep weaken and Decrease Def on CB, unless it’s magic affinity. What if you dont have Ma’shalled? Theoritically you can make her work. If you use the Batman comp, Delver may be enough because her A1 can hit heal reduction debuff. However, if you want more consistency, consider using the cursed artifact set that has a 50% chance to land heal reduction debuff on one of the champions.
