Balancing and Reskinning
Keeping fights on the ladder
Root and Stem balances itself through two simple ideas, and your job as a builder is mostly to not fight them. First, every meaningful action resolves on the graduated Action Roll: your bonus stack becomes a Skill-to-Challenge Ratio (SRC), the SRC picks a die (d4 up to d100), and the result is graded into five tiers. Second, difficulty is a required tier, not a flat number — Trivial asks for Tier 2+, Easy and Standard for Tier 3, Hard and Very Hard for Tier 4, and Heroic and Nearly Impossible for Tier 5.
When you weigh an encounter, compare those tiers directly. The Universal DC does the same work for contests against the world: it is precalculated before the event from the raw level-to-level and stat-to-stat comparison, so a high-Tier, high-stat actor facing a low-stat pebble earns a low DC. Build your monsters and obstacles so their challenge lands in a band your party's SRC can actually reach, and you never have to invent a number mid-scene.
Scale by Tier and Material Tier
Creatures and objects alike grow along one shared ladder: Tier runs 0 (a pebble) to 10+ (cosmic). A creature's size, durability, and raw stats are sized to its Tier, and its resistance is its Material Tier — MT = CON + Tier + density/armor. The Pebble Principle keeps this honest: an impact is an Effective Strike (Force × force-mult + Precision × precision-mult) against the target's MT, and small-but-precise beats big-but-dumb.
| What grows with Tier | Why it matters |
|---|---|
| HP = 20 + (CON × 5) + (level × 5) | survivability is already tied to CON and level |
| Mana = (INT + WIS) × 3 | casting budget scales with the mind stats |
| MT = CON + Tier + armor | what you can dent, break, or crater |
The trap to avoid is anything that inflates survivability or damage past its Tier — free healing, cost-refunding gear, bonus damage that ignores MT. Those are invisible to the tier math and will quietly make fights easier (or brutal) the longer your campaign runs. Aim such content at story utility, not combat throughput.
Reskinning to a setting
Moving the system into a new genre is mostly a matter of emphasis:
- Pick your elements. Magicules is everywhere, but you choose what's loud — a fire-and-earth fantasy leans on those Primal Elements, while a light-and-shadow game foregrounds the Creation–Entropy Higher Elements.
- Set your Classes and Tiers. Decide whether Characters, Creatures, Nature, or Objects dominate, and at what Tier the stories live.
- Build to the six-Stat model. Species, locations, and world content all describe things with STR, DEX, CON, INT, WIS, and CHA — and the graduated Action Roll stays the spine no matter the skin.
Lean on the Universal DC for every contest and the Creation–Entropy reclassification rule for the world's physical honesty: a living tree is Nature, and when it dies it is reclassified as an Object. That single rule keeps your setting consistent from a living seedling to a fallen log.
The test
Before you ship, build one character and one encounter entirely from your content, resolving both through the Action Roll and the Universal DC. Where you had to improvise a number, the tier and stat math above has the answer; where you had to invent a rule, reconsider — the engine almost certainly already has a lever.
