The Stella system in Raven 2 looks overwhelming at first—stars, nodes, amp points, knives, rerolls, colors—but once you understand what actually matters, it becomes one of the cleanest long-term power systems in the game.
Here’s the key idea up front:
Stellas themselves are not the main power – the real strength comes from your Stella Amp and the stats you roll in Amplification.
This guide will walk you through:
- How Stellas and builds work
- What Amp Points are and how to maximize them
- Which parts you should ignore so you don’t stress over tiny RNG procs
- How Amplification, carving knives, and Teramons really work
- Reroll strategy so you don’t burn your account’s resources for nothing
1. Stella Basics – What This System Actually Is
When you open the Stella screen, you’ll see:
- Multiple slots/nodes where you insert Stella emblems
- A Stella Amp value at the bottom (this is the big one)
- Up to three different build presets you can swap between
Those three builds are perfect for:
- One PvE farming build (XP/mob grind)
- One Boss / Single-target build
- One PvP build
You unlock more Stella slots as you level up, and filling those slots with better Stellas increases your Amp Points, which unlocks more Amplification nodes (the real stats).
2. Amp Points Matter More Than Individual Stella Effects
Each Stella has:
- A rarity (Common / Rare / Heroic / etc.)
- A tiny effect with a low chance to trigger
- A Stella Amp value (points)
The Amp value is what you should care about most.
- Rares might give around 6 Amp
- Heroics around 10 Amp
- Higher rarity = more Amp
You also get Set Amp points when you equip Stellas from the same set. For example, having pieces of a certain group together gives you extra bonus Amp.
So your main priorities when equipping Stellas should be:
- Highest rarity first (more Amp)
- Maintain or improve set bonuses (Set Amp)
- Only then worry about the actual Stella effect text
The truth is:
Most Stella effects are low-proc, low-impact bonuses. They’re nice, but they don’t define your build. Your Amplification stats do.
3. Do Stella Effects Stack?
A common question:
“If I equip two of the same Stella, do the effects stack?”
The community doesn’t even fully agree on this because the effects are so minor and so RNG-based that it barely matters.
My advice:
- Don’t overthink stacking
- Use basic logic with your class:
- Basic-attack-heavy class? Effects that trigger off basic attacks are more valuable
- Skill-based caster? Skill-related effects make more sense
But again: Do not build your entire setup around the tiny effect text. If that’s your focus, you’re wasting the real potential of the system.
4. Amplification – The Real Core of the Stella System
Now we get to where the system actually gets strong.
The Amplification tab gives you:
- Flat and percentage-based stat bonuses
- Custom rolls per slot
- Additional bonus effects when all three rolls reach certain rarities
You can change these stats using:
- Stella Carving Knives
- Teramons (your hard limiter)
Carving Knife Rarities & Usage
Each Amplification slot uses a certain knife rarity:
- First two rolls → Common knives
- Next set of rolls → Uncommon knives
- Then → Rare knives
- Later → Heroic / higher (depending on the slot)
You can craft higher-tier knives from lower ones:
- Example: 3 Common knives → 1 Uncommon knife
So don’t panic if you only have low-tier knives; they convert upward.
5. Teramons – The True Bottleneck
Teramons are used when you reroll Amplification stats, and this is where players destroy their resources without realizing it.
How it works:
- Rolling with no locked stats only costs knives
- The moment you lock a stat (to keep a good roll), rerolling starts to cost Teramons
- Lock more stats → Teramon cost increases dramatically
Example:
- No locks → 0 Teramons per reroll
- Lock 1 stat → maybe 5 Teramons
- Lock 2 stats → maybe 25 Teramons
- Lock 3 stats → expensive, fast
You use Teramons for a lot of systems in the game, so burning them all on one Amplification line is a bad idea.
Golden rule:
Only lock stats that are genuinely strong and future-proof for your build.
6. Roll Colors & Additional Effect Thresholds
Each Amplification slot has up to three lines:
- Stat 1 (top)
- Stat 2 (middle)
- Stat 3 (bottom)
Each stat can roll at different rarities:
- Purple – Heroic
- Yellow – Legendary
- Red – Mythic
Many Amplification nodes have extra text like:
- “Heroic grade or higher”
- “Legendary grade or higher”
- “Mythic grade or higher”
This means:
You only get that extra effect if all three stats reach at least that rarity.
Example:
- You roll 2 Red lines and 1 Purple line
- Since Purple is the lowest rarity, your active extra effect is only “Heroic grade”
- To unlock Legendary grade, the Purple must become at least Yellow
- To unlock Mythic grade, all three must be Red
So even if two stats are godlike, a single low-rarity third stat limits the extra effect tier you actually receive.
7. Reroll Strategy – How Not to Waste Your Resources
Here’s a practical reroll approach:
1. Roll Until You See High-Rarity (Red/Yellow)
- If you get a strong Red on an important stat (Attack, Final Damage Amp, etc.), lock it
- Keep that line safe and reroll others
2. Understand the Rate Table
Each node lets you view the rates:
- Shows which stats can appear
- Shows their percentage chance
- Some good stats (like Attack +x or Final Damage Amp) often have lower rates → more valuable
Use that to decide whether to keep a roll or chase a better one.
3. Don’t Chase One Perfect Line at the Cost of Everything
It’s easy to tunnel-vision for “perfect triple red,” but the Teramon cost and time cost is absurd.
Instead:
- Aim for one or two strong Reds and a decent third line
- Get to at least Heroic or Legendary grade bonus
- Move on and upgrade other Amplification nodes
Your overall account gets stronger faster if you make many solid nodes instead of one perfect node.
8. Practical Setup Flow (Step-by-Step)
If you’re just starting to optimize Stellas and Amplification, do this:
- Equip your highest rarity Stellas in all open slots
- Check the Amp Points in the top-left of each Stella
- Favor higher Amp values and maintain set bonuses
- Hit reasonable Amp thresholds to unlock multiple Amplifications
- More unlocked nodes = more total stats gained
- Go to Amplification and roll each unlocked node
- Use Common knives first on early slots
- Don’t lock anything until you see a genuinely strong roll
- Lock only high-value stats
- Attack, Final Damage Amp, Crit-related stats, class-specific specialties
- Once locked, watch your Teramon usage closely
- Upgrade your worst nodes slowly over time
- When you get more knives and Teramons, revisit low-rarity rolls
- Try to push more nodes into Heroic/Legendary grade effects
- Use different build presets
- PvE preset: damage and speed
- Boss preset: survivability + single-target power
- PvP preset: resistances, CC res, defensive stats, etc.
9. What Really Matters Long-Term
To sum it all up:
- Don’t obsess over Stella effect text – they’re minor and RNG-based
- Stack Amp Points first – rarity and sets matter far more
- Amplification is the true endgame – treat each node like a mini piece of gear
- Teramons are precious – lock with intent, not on impulse
- Aim for strong, efficient red rolls, not perfection
