With an 84.4% approval rating, over 375,000 visits, and 210-542 concurrent players, the game has built a dedicated community quickly.

This guide covers every working code for May 2026, the full race tier list, the skill mastery system, best spirits, and the optimal prestige strategy.

All Active Tensura Incremental Codes (May 2026)

Tensura Incremental codes give Race Rerolls, Skill Rolls, and Spirit Rolls. Race Rerolls let you reroll your starting race until you land an S-Tier pick. Skill Rolls give chances at powerful abilities. Spirit Rolls determine which elemental companion you can equip. Redeeming every code below before you start playing gives you a massive head start.

Here is the full list of working codes as of May 2026:

That is 39 codes in total. Redeeming all of them gives you enough Race Rerolls to nearly guarantee an S-Tier race and plenty of Skill and Spirit Rolls for a strong opening build. Vaelora releases new codes at visit and Discord member milestones.

How to Redeem Codes in Tensura Incremental

Code redemption requires a prerequisite that trips up many new players. Follow these steps exactly:

1. Join the Vaelora Roblox Group — This is mandatory. Codes will not work if you are not a group member. Search for "Vaelora" in the Roblox Groups tab and click Join.
2. Launch Tensura Incremental — Open the game from the Roblox page (Place ID: 74982282775557).
3. Open Settings — Click the Settings button, which is usually a gear icon in the corner of your screen.
4. Enter Your Code — Type or paste the code exactly as shown. Codes are case-sensitive.
5. Click the Green Redeem Button — If the code is valid and you have not already used it, your rewards will appear immediately.

If a code says "invalid," double-check that you have joined the Vaelora group and that you have not already redeemed that specific code. Each code can only be used once per account.

Getting Started — Your First 30 Minutes

Your first half hour determines how smooth the rest of your progression will be. Knowing what to prioritize saves you from wasting time on suboptimal strategies.

Step 1: Redeem Every Code

Before you fight a single enemy, go to Settings and redeem all 39 codes listed above. The Race Rerolls alone are worth the time investment. Starting with the right race is the single biggest factor in your long-term progression speed.

Step 2: Reroll for an S-Tier Race

Use your Race Rerolls immediately. You want Slime, Vampire, or Daemon. These three have the highest stat ceilings and the best passive abilities. Save leftover rerolls for after prestige. A-Tier races like Ogre or Elf are playable but will fall behind S-Tier in late-game content.

Step 3: Pump Endurance

During your first 30 minutes, put everything into Endurance. Surviving longer means more enemies devoured per run, which means more power stolen and faster evolution. Shift to offensive stats once you can reach the second or third area without dying.

Step 4: Devour Everything

The core loop is straightforward: defeat enemies and devour their abilities. Each devoured enemy can give you new skills or upgrade existing ones. Focus on devouring different enemy types early to build a diverse skill pool, then specialize once you know which skills synergize with your race.

Race Tier List — May 2026

Your race determines your base stats, passive abilities, and how well you scale into late-game content. Here is the current tier list based on community testing and endgame viability:

S-Tier Races

A-Tier Races

If you rolled an S-Tier race, commit to it. A-Tier races can clear all content but require more optimization and better spirit choices to keep up in group content.

Skill Mastery System Explained

Skill mastery gates your evolution. You cannot evolve until every skill reaches 100% mastery. The game hard-locks evolution behind full mastery with no shortcut.

How Mastery Works

Every skill use in combat increases its mastery percentage. Higher-tier skills need more uses to reach 100%. The key insight: mastery is based on skill uses, not damage dealt.

The Boss Farming Trick

Because mastery counts each use regardless of damage, the fastest way to grind mastery is to equip low-damage, high-hit-count skills and use them on bosses. Bosses have large HP pools, so they survive long enough for you to land dozens of skill uses per fight. A skill that hits 5 times per use gains mastery 5 times faster than a single-hit skill, even if the single-hit skill deals more total damage. Target bosses you can comfortably survive against — the mastery gain rate is the same regardless of boss difficulty.

Best Spirits Ranked

Spirits are companion entities that provide passive stat bonuses and can influence your build direction. You obtain spirits through Spirit Rolls, which you get from codes and in-game progression. Not all spirits are created equal — here are the ones worth aiming for:

Spirit choice matters most when paired with the right race. Greater Holy on Vampire is nearly unkillable. Greater Fire on Daemon maximizes burst damage. Greater Dark on Slime accelerates your devour loop. If you roll a matching Greater-tier spirit, lock it in.

Prestige Strategy & Progression

Prestige is where most players make their biggest mistake. Pushing every run to the highest evolution feels productive but is actually the slowest way to progress.

The 2-3 Evolution Rule

The optimal strategy is to evolve 2 to 3 times per run and then prestige. The time to reach each subsequent evolution increases exponentially, but prestige rewards scale linearly. By capping runs at 2-3 evolutions, you accumulate prestige currency faster over the same total play time. After several quick prestiges, your boosted stats will make later evolutions trivially easy.

When to Push Further

The exception: if you are very close to a new evolution and mastery is almost complete, finish it before prestiging. Also, if a content update adds rewards tied to a specific evolution tier, do one long run to unlock it, then return to short cycles.

Avoiding Hybrid Builds

Hybrid builds do not work in this game. The stat scaling heavily rewards specialization. Splitting points between physical and magic damage leaves you mediocre at both. Pick one path and commit for the entirety of each prestige cycle.

Game Passes Breakdown

Tensura Incremental offers three game passes, all structured around the "Tester" tier system. These passes support the developer and give you access to additional features:

The Tester pass at 399 Robux is the best value for supporting Vaelora and getting early access. Higher tiers are for dedicated players who want deep involvement in development. None of these passes are required to progress — all gameplay content is accessible to free players. If you want a game pass without spending real money, Earnaldo lets you earn free Robux through simple tasks.

Boss Farming & Combat Tips

Bosses in Tensura Incremental serve two purposes: they drop valuable loot, and they are the best targets for farming skill mastery. Here is how to approach boss fights efficiently at every stage of the game.

Early Game Bosses

In the starting cave, your first boss appears after devouring enough regular enemies. Equip multi-hit skills and use the fight to grind mastery rather than bursting it down. The first boss telegraphs big swings with a wind-up animation — dodge those and attack during recovery. With enough Endurance, you can master one or two skills in this fight alone.

Mid Game Boss Strategy

After your first evolution or two, match your spirit element to each boss's weakness. Greater Fire deals bonus damage to nature-themed bosses, and Greater Dark is strong against holy enemies. Check the boss's element tag before engaging and swap spirits accordingly.

Raid Bosses

Raids unlock after your first prestige and require coordination with other players. Vampire players with Greater Holy should focus on sustain and consistent damage. Daemon players with Greater Fire should save burst for stun phases. Communication through in-game chat makes raid clears much smoother.

Dungeon Tips

Dungeons are multi-stage encounters where each floor increases in difficulty, ending with a boss that has unique mechanics. Make sure all your skills are mastered and your spirit is equipped before entering. If you are dying in the second dungeon zone, you need more Endurance — go back and farm regular enemies until you can survive at least 3 boss hits without healing.

Advanced Tips for Experienced Players

• Track your mastery per minute — Time how long each skill takes to reach 100%. If one skill is significantly slower, it is bottlenecking your evolution speed.
• Stack devour bonuses — Slime players should prioritize any spirit or equipment that increases devour rate. Even a 5% increase compounds over a full prestige cycle.
• Save ultimates for stun phases — Ultimates have long cooldowns. Use them during boss vulnerability windows to maximize damage output.
• Join the Vaelora Discord — The community posts tier list updates and build guides after every balance patch. The meta shifts regularly.
• Prestige before logging off — Even a short run that only reaches one evolution is better than leaving progress on the table mid-run.
