Upgrading and prioritizing champion skills in RAID: Shadow Legends is one of the most impactful ways to boost your team’s power and complete milestone offers quickly—even as a no-spend or low-spend player. This guide will help you make the most of your rare Skill Tomes and champion upgrade resources, so you can progress efficiently, avoid common traps, and understand exactly which skills are worth your hard-earned investments.
Understanding Skill Upgrading Basics
Before diving into specific strategies, it’s crucial to understand how skill upgrading works in RAID: Shadow Legends. Champions come with 1 to 3 active skills (plus some with a passive and/or aura). Improving these skills requires Skill Tomes that match the champion’s rarity (Rare, Epic, or Legendary). Skill upgrades apply randomly to any non-maxed skills—so you can’t directly select a particular ability to upgrade, which adds a layer of strategy to resource management.
Skill Tomes are extremely limited and valuable, especially for Epic and Legendary champions. You might also come across duplicate lower-rarity champions (“food”) that can be used to upgrade skills for common or rare champions, but this method is less relevant as you progress and shift focus to higher-rarity units.
Keep these upgrade basics in mind:
- Skill Tomes are rare rewards from events, Clan Boss, missions, and some milestones.
- Upgrades are random—use caution, as poorly-timed tomes can be wasted.
- Not all champions are worth booking (using tomes on).
- Prioritize champions that you will use for months, not just for the current offer campaign.
Which Champions and Skills Should You Prioritize?
Choosing where to spend your Skill Tomes is the single most important decision for efficient progression. It’s tempting to use your first few tomes on any strong champion in your roster, but with limited resources, you need to invest where it really counts.
Prioritize Skill Tomes based on the following:
- Your main campaign farmer: Champions like Kael, Athel, or Elhain (starter champions) drastically improve farm speed and consistency with booked AoE (area-of-effect) skills.
- Core progression champions: Supports, revivers, or damage dealers you plan to use in dungeons, Clan Boss, Arena, and Faction Wars for an extended time.
- Game-changing abilities: Certain skills can unlock new content or make difficult content much easier—especially reduce cooldowns for heals, revive, or AoE nukes.
As a practical example, booking Kael’s A2 and A3 can significantly speed up your farming and campaign progress. Clan Boss-focused champions such as Athel (for Poison or Weaken debuffs) can also unlock key milestones and rewards when booked early.
Avoid investing tomes in:
- Early-game “food” or throwaway champions.
- Champions you do not plan to keep using long-term.
- Champions you’ve drawn as part of a short-term fusion event, unless they’re top-tier meta picks.
It’s wise to look up tier lists or guides for champion evaluations if you’re not sure, or check out the in-game ratings and community resources. A little research can save you months of regret over wasted tomes.
Efficient Skill Upgrading and Tomes Management
With skill upgrades being random for each champion, it’s easy to waste tomes if you rush. For maximum efficiency, follow these best practices for upgrading skills:
- Book champions with fewer upgradeable skills first. Fewer available upgrades means a higher chance the tome lands where you want it.
- If a critical skill (like an AoE nuke or revive) is not yet upgraded, consider waiting until you’ve used other basic skill books to increase your odds of hitting the right ability.
- For rare champions, use duplicate champions for skill upgrades whenever possible—save Rare Skill Tomes for truly impactful picks.
- For Epics and Legendaries, resist the urge to spend tomes impulsively. These resources will quickly become a choke point as you build your late-game roster.
Remember that managing resources well brings exponential returns. Champions with their most valuable skills booked perform better in nearly every game mode, helping you complete milestones and offer requirements faster.
A bonus tip: Some upgraded skills reduce ability cooldowns, letting you cycle through healing, buffs, or damage moves more often. The effect is immense, especially in dungeon runs and boss battles where every turn matters.
Progression Milestones and Efficient Strategy
To finish milestones or offer challenges efficiently, focus your efforts on a narrow pool of core champions. Aim to funnel your upgrade resources (including Level, Rank, Ascension, Gear, and Skills) into this group rather than spreading investments thin.
Your strategic priority should look like this:
- Identify your campaign farmer and prioritize maxing their most important skills. This will cut down time spent farming XP, silver, and artifacts.
- Upgrade the key skills on your main boss-killers, healers, and support units to tackle dungeons and Clan Boss. This enables you to hit account progression rewards sooner and increase daily resource income.
- Actively participate in daily events, Clan Boss, and Arena to earn tomes, shards, and other progression loot. Tomes are often part of login and milestone rewards—don’t miss out.
- If your goal is to clear a certain stage for an offer, trace back which champion or specific skill is the true bottleneck and focus your tomes there first.
For players aiming to maximize resource generation (silver, shards, XP) or progress efficiently through early and mid-game, it’s crucial to use energy smartly. For tips on how to do this, you can refer to this guide on maximizing energy use efficiently in RAID: Shadow Legends. Combining efficient energy use with wise skill upgrading creates a synergy for fast, efficient progression.
Common Mistakes and Traps to Avoid
Skill Tomes are precious, so common mistakes can easily set you back and slow milestone progress. Avoid these frequent traps:
- Wasting tomes on early-game champions that you’ll soon replace.
- Booking Epics or Legendaries just because you pulled them, without checking if they’re actually strong.
- Overbooking a champion with many skills, especially when only one or two of their skills are worth improving—the odds are against you.
- Missing out on duplicate champions for Rare skill upgrades, thus losing a free and easy resource.
- Upgrading “fun” skills before “necessary” team-impact abilities—prioritize your campaign farmer, dungeon all-stars, or core Clan Boss picks first.
Be patient with upgrading. Building out a strong roster for endgame can take months, and careless tome use in the opening weeks can create long-term regret.

Advanced Tips for No-Spend and Low-Spend Players
If you’re playing without spending (or spending very little), you need to squeeze even more value from every skill upgrade. Here’s how:
- Hoard your Epic and Legendary Skill Tomes until you’re certain about your core champions. Wait for a champion that fits multiple roles (Arena, Clan Boss, Dungeons) to appear before investing.
- Participate in all major events and daily login bonuses. Many offer Skill Tomes as reward milestones—prioritize these where possible.
- Save your duplicate rares for skill upgrades before sacrificing them for rank fusion.
- Carefully plan fusion events. Sometimes fusion champions require skill upgrades—ensure you don’t waste books on transitional units that get replaced quickly.
- If you need to “stretch” your team, book only the critical skill (such as a main AoE nuke on your campaign farmer) and save the rest for future units.
Staying disciplined ensures you’ll have the right toolkit of upgraded champions exactly when endgame content demands it, without being forced into uncomfortable spending.
Conclusion
Efficiently upgrading and prioritizing skills in RAID: Shadow Legends is one of the most effective ways to power up your roster for milestone completions and offer progression. Focus your tomes where they matter most—on key campaign farmers and enduring meta champions—manage upgrades wisely, and avoid the pitfalls of wasteful booking. With a bit of patience, strategy, and the right information, you’ll collect rewards faster and make every skill upgrade count.
