- Merges the mana of Ars Nouveau, Mana and Artifice, and Iron's Spellbooks into one Peril meter; casting, spending mana, and being drained all raise it.
- At 60% the screen edges turn blue, at 70% the heartbeat rises, at 80% a warning sounds, and at 100% a seven-second overload begins.
- Use
Shift + Rto spend health and cool Peril. - During overload, casting and interactions are locked, movement slows, and holding
Rvents; reach 95% within seven seconds or explode. - Heartstop only delays the overload; it does not remove the danger.
- The HUD percentage hides when Peril is zero.
- Default weights are Ars 30%, MNA 10%, and Iron 50%, giving a Peril cap of about 90% of total mana with all three installed and the same ~90% normalization for a single mod.
- Mana restoration cools at half that rate, and natural decay is ×0.7 from 40–70% and ×1.5 above 70%.
- Normal venting is 3× natural decay and costs 0.4 health every 0.5 seconds; overload venting costs 5× that health.
- With unified casting on, all three mods stop checking or consuming native mana: Ars adds Peril, blocks reactive casting at 100%, and hides its bar; MNA refunds direct drains into Peril, blocks Eldrin restoration at 100%, and replaces its HUD with the affinity/level HUD; Iron opens spell, channel, and client mana checks, lets Heartstop delay the overload and explosion damage, and hides its bar; turning unified casting off restores the original costs and HUDs.
- Thresholds, effects, and HUD settings are configurable.
