Make every spell tier reachable and every common artifact useful

[XxFran10xX]

Summary

A player reported that the mage class can't progress with the server numbers. This ships the values now live on TFMCMain01, so new installs and reference configs match.

• Tier IV was impossible. charges.yml bands were 10 / 40 / 75 / 110, but the same bands gate casts against the caster's resonance, which stops at max_resonance (100). Bands are now 10 / 35 / 65 / 95. A comment explains why the top band has to stay at or below max_resonance.
• Commons often couldn't unlock tier I. The common aura cap was 0-25, so about 40% of commons rolled below the tier I threshold of 10. Meditation can't raise resonance above the circle's stored aura, so those artifacts were dead weight. The common cap is now 10-25 for the rarity fallback and the four planar schools. The death arts, arcanum, spirit and illusion keep their own ranges.

Weapons and charges store raw aura, so existing items re-derive their bands. Existing artifacts keep the caps they rolled. Live copies of both files are never overwritten by the jar; Main and Dev already run these values.

Testing

• Rebased onto main (765f822). CI mvn clean verify passes on Linux with the 100% coverage gate.
• Locally (Windows, Java 21) all config, charge, artifact-generation and resonance-cast tests pass; the only failures are the gear-ownership/profile file-store tests, which fail on Windows only (AccessDeniedException on atomic moves, case-insensitive paths) and pass in CI.
• TFMCDev01, 2026-10-17, PR build magic-DEV-20261017-0004.jar, with the live charges.yml and artifacts/generator.yml moved aside so the jar wrote its bundled defaults:
  • Startup loads 4 charge tiers, 1 band table and all 10 artifact types with no Magic errors.
  • The fresh defaults match the values live on Dev and Main (only the new comment differs).
  • magic weapon give on a bot: aura 9 refused (below band I); 10 and 34 give Mitlan I, 35 and 64 II, 65 and 94 III, 95 and 100 IV.
  • 40 magic artifact roll mitlan common rolls all landed in 10.67–24.71.
• 2026-10-05 Dev cast test (seeded character): tier IV casts at 95 and 100 resonance, refused at 94; tier III at 65/64; tier I at 10/9. Character seeding no longer works on RPCharacters 2.24 bots, so the 10-17 run checked the bands through weapon attunement instead.
• Live on TFMCMain01 as config since 2026-10-05 20:50 UTC through magic reload.

📝 Summary

Summary by CodeRabbit

• Gameplay Changes
  • The common rarity aura range now starts at 10 instead of 0 for global settings and the Cerrith, Seithr, Oseni and Mitlan types. Other rarity and type caps are unchanged.
  • Charge bands now use thresholds of 10, 35, 65 and 95. These bands also gate spell casts based on caster resonance, which is capped at 100 by default; the highest band should not exceed that cap.

The pull request changes the global and selected artifact common aura caps. It also changes the default charge-band thresholds and updates comments about caster resonance.

Changes: Common aura caps

Layer / File(s)	Summary
Update common aura caps src/main/resources/artifacts/generator.yml	The global common aura cap and the caps for cerrith, seithr, oseni and mitlan change from 0-25 to 10-25.

Charge bands

Layer / File(s)	Summary
Update default charge bands src/main/resources/charges.yml	The default thresholds change from 10/40/75/110 to 10/35/65/95. Comments describe how the bands gate spell casts against caster resonance, note the default cap of 100, and state that the top band should not exceed that cap.

Change: Bug fix

Merge Risk: 🔵 Low · up to 12bbc

Installations with custom aura ceilings below 10 may skip the four affected artifact types. The shipped setting avoids this; check custom settings or raise the ceiling before merging.
