RAID: Shadow Legends: How to Reach 400+ Speed with Impulse Gear

To reach 400+ Speed (such as the 407 Speed benchmark) using Impulse gear in RAID: Shadow Legends, you must equip at least eight pieces across your six artifact and three accessory slots. This activates two full Impulse set bonuses, granting +24% Speed alongside two independent 30% chances to reduce skill cooldowns. Achieving this velocity requires a champion with a high base Speed (110 or higher), 6-star Speed boots with Sand Devil ascension, triple or quad Speed substat rolls on almost every piece, and high-tier Speed Glyphs.

Impulse Set vs. Traditional Speed Sets

A four-piece Impulse set provides +12% base Speed and a 30% chance to reduce a random skill cooldown by one turn at the start of the champion's turn. Equipping eight or nine pieces activates the bonus twice.

While three standard Speed sets offer 12% more base Speed scaling, Impulse trades that extra percentage for skill resets. On turn-meter boosters like Arbiter, Siphi the Lost Bride, or Shu-Zhen the Valorous, cycling active skills quickly prevents enemy teams from stabilizing if your initial assault does not wipe them out.

Stat Requirements for a 407 Speed Build

Reaching 407 Speed requires multiplying innate champion base Speed and layering maximum flat substats:

Total Speed = [Base Speed × (1 + % Set Bonuses + % Lore of Steel)] + Flat Gear Speed + Flat Glyphs

On a champion with 115 base Speed (such as Shu-Zhen the Valorous), the stat targets break down as follows:

• Percentage Scaling: Two Impulse set bonuses (+24%) add 27.6 Speed. The Lore of Steel mastery (+5% of total set bonuses) adds roughly 5.75 Speed, bringing the champion to approximately 148 Speed before flat additions.
• Boots: 6-star rank boots provide +45 flat Speed. Ascending those boots to rank 6 with Sand Devil oils adds up to +12 bonus flat Speed.
• Top-Row Artifacts (Weapon, Helmet, Shield): Each piece requires at least a triple roll into the Speed substat, providing 20 to 24 flat Speed per item.
• Bottom-Row Artifacts and Accessories: Gloves, Chest, Ring, and Amulet require native double or triple Speed substat rolls. The Banner requires either a primary Speed stat (+35 Speed at 6-star rank 16) or a high-rolled Speed substat.
• Speed Glyphs: Applying 5-star and 6-star Speed Glyphs across all eligible gear contributes an additional +40 to +64 flat Speed.

Forge Crafting Strategy for Impulse Gear

Impulse materials are limited by Forge Pass milestones and event rewards. Use crafting charms on every attempt to maximize high-speed yields:

1. Rank Charm: Guarantees a 70% chance to craft 6-star gear. Five-star pieces cannot roll high enough substat values to hit the 400+ threshold.
2. Rarity Charm: Increases the drop rate of Legendary and Mythical pieces, ensuring the item begins with three or four unlocked substats.
3. Speed Substat Charm: Forces Speed into the substat pool, maximizing the chance of getting upgradeable rolls.

Target top-row artifacts (Weapons, Helmets, and Shields) first. Their primary stats are fixed (Flat ATK, Flat HP, and Flat DEF), eliminating primary-stat variance and allowing you to focus entirely on rolling Speed substats.

Substat Upgrading and Gear Tuning

Upgrade your crafted pieces systematically to conserve silver and enhancement materials:

• The Level 8 Check: Upgrade any Epic, Legendary, or Mythical piece containing a Speed substat to Level 4. If the first roll misses Speed, take it to Level 8. If an Epic piece misses Speed twice, sell it immediately, as it can no longer hit the necessary triple roll.
• Mythical Red Substats: Mythical pieces with an innate red Speed substat can upgrade five times (penta-roll), reaching over 30 flat Speed on a single item before glyphs. Prioritize these items for upgrading.
• Chaos Ore Usage: Save 6-star Chaos Ore exclusively for 6-star Legendary or Mythical pieces that rolled multiple times into undesirable flat stats. Chaos Ore rerolls all substats while preserving rank and rarity, offering a second chance at Speed rolls.
• Glyph Application: Apply 6-star Speed Glyphs only to items that have secured at least a triple roll in Speed. If a 6-star glyph rolls low (+3 or +4), overwrite it during Clan vs. Clan events until it reaches +7 or +8.
• Team Speed Tuning: A 407 Speed lead widens the gap between your booster and the rest of your team. Ensure your secondary crowd controller or debuffer is tuned to at least 70% to 75% of your booster's total Speed to prevent enemy cut-in passives or Reaction accessories from interrupting your turn rotation.
