Tablets (石板) are the most important strategic element in Sephiria's inventory system. A well-placed tablet can double your build's effectiveness; a poorly placed one can waste your best artifacts. This guide covers everything: how tablets work, placement strategies, rune imprinting, and build-specific recommendations.
How Tablets Work
- Tablets occupy grid space just like artifacts — they have physical shapes and take up cells.
- Tablets upgrade artifacts — when placed correctly, they raise the level of adjacent or connected artifacts.
- Tablets have positional effects — some affect the row they're in, some affect columns, some affect a radius around them.
- Tablets can be rotated — use Q/E keys to preview and rotate before committing.
- Tablets can unlock permanent effects — via the Rune Imprint system (Survival talent 20).
Tablet Types by Effect Area
| Type | Effect Pattern | Best For |
|---|---|---|
| Row Tablets | Upgrades every artifact in the same row | Linear builds with artifacts in a straight line |
| Column Tablets | Upgrades every artifact in the same column | Vertical artifact stacks |
| Radius Tablets | Upgrades artifacts within a surrounding area | Clustered artifact groupings |
| Adjacent Tablets | Only upgrades artifacts directly touching the tablet | Precision upgrades for key items |
| Conditional Tablets | Upgrades based on artifact type or combo | Synergy-specific builds |
Rune Imprint System
When you unlock Rune Imprint:
- You sacrifice 12 bag slots (permanent cost)
- In exchange, tablet effects are permanently embedded in your bag
- These embedded effects work on every run, without needing to find and place the tablet
- This completely bypasses the Plunder modifier (which fixes boss tablet drops to Rare/Common) — your rune effects are permanent
Placement Strategy: The 3-Step Method
Step 1: Identify Your Core Artifacts
Before placing anything, identify which 3-4 artifacts are the heart of your build. For the Plasma build, that's Magma Orb, Thundercloud Compass, and Oink Shaman's Necklace. These are the artifacts you want to upgrade with tablets.
Step 2: Cluster Core Artifacts
Place your core artifacts adjacent to each other, in a shape that a single tablet can cover. For example, if you have a row tablet, place all three core artifacts in the same row. If you have a radius tablet, cluster them in a tight group.
Step 3: Layer Tablets for Maximum Coverage
Place your first tablet to cover all three core artifacts. Then place a second tablet overlapping the same area. Each tablet's upgrade stacks — two tablets covering the same row can triple an artifact's effective level.
Build-Specific Tablet Recommendations
Plasma Judgment Staff Build
- Use Row tablets — place Magma Orb, Thundercloud Compass, and Oink Shaman's Necklace in a single row
- Prioritize elemental amplification tablets
- Save Fretted Clay Tablet for covering the Magma Orb (the ignition source)
Poison Build
- Use Radius tablets — Black Tea Leaf Pouch, Red Cloth Piece, and Neutralizer Black should be clustered
- Prioritize debuff amplification tablets
- Conditional tablets that boost poison-type artifacts are ideal
Sacred Jar Companion Build
- Use Adjacent tablets — companion artifacts (Mysterious Weight, Wings, Mining Overseer Armband) benefit from direct contact
- Prioritize summon enhancement tablets
Common Tablet Mistakes to Avoid
- Placing tablets before artifacts — always place artifacts first, then fit tablets around them. Tablets are flexible; your core artifacts aren't.
- Wasting tablet space on non-core artifacts — if a tablet covers a core artifact AND a non-core one, that's fine. But don't move your tablet just to cover a non-core item.
- Forgetting to preview — always use Q/E to preview. A tablet placed without previewing can cover nothing useful.
- Ignoring the side bag — unusual-shaped tablets that don't fit your grid can go in the side bag. Don't force them into bad positions.
- Not using Rune Imprint — if you have Survival 20, always imprint your best tablet. It's a permanent buff that never goes away.
Tablet Priority for Early Runs
If you're early in the run and have limited tablet options:
- Row tablets that cover 3+ artifacts — highest value
- Radius tablets covering your core cluster
- Conditional tablets matching your build type
- Adjacent tablets for single high-value artifacts
- Save unusual tablets — they may become powerful once your build is complete
