Status effects

Status effects can modify attributes, control actions, carry a combat stack or run their own update. Their removal rules matter as much as their bonuses: milk, harmful-effect cleansing and ordinary expiry do not all use the same contract.

Reading the catalogue

The tables show the registered effects at level I, which corresponds to amplifier 0. “Base” and “total” distinguish the operation used by a proportional attribute modifier; flat numbers are additive. Spirit Mantle explicitly keeps the same modifiers at every amplifier. An effect’s duration usually comes from the weapon, potion, power or command applying it.

“Milk-clearable” describes this mod’s milk hook. An effect marked “No” can still end naturally or be removed by its owning gameplay system. Energy Inefficiency additionally survives the general clear-all path because it is persistent. Harmful-effect cleanses exclude beneficial, unclearable and persistent effects.

Periodic damage

For these formulas, a = max(0, amplifier). Ordinary periodic ticks have no attacker attribution and mark their damage as periodic with no ordinary hurt cooldown.

The shift halves the base interval once per step before the minimum applies. Updates depend on remaining duration being divisible by the interval. Poisoned uses ordinary magic damage calls and does not implement a “leave 1 health” rule.

Magic vulnerabilities and exhaustion

These additional registered effects use Spell Power’s vulnerability implementation. The dependency behaviour below was checked in the local official-source snapshot 9cdd503, whose build declares 1.6.0 for Minecraft 1.20.1, corresponding to the configured 1.6.0+1.20.1 dependency. This is source verification, not a binary-equivalence check.

Each current definition calls the vulnerability setter twice. In that source, the setter stores a single school and replaces the earlier call. Therefore only the last school survives:

The surviving tuple is (1.15, 0, 0.10): added base-power multiplier, added critical chance and added critical damage. Spell Power multiplies it by amplifier + 1, adds contributions from applicable effects, and uses base × (1 + added multiplier). At amplifier 0, an isolated matching effect therefore yields 2.15 × base, not 1.15 × base; it adds 0 critical chance and 0.10 critical damage. The replaced (1.30, 5, 0.20) tuple is not a second active school bonus. Iced also carries movement speed -10% total at level I.

Energy Inefficiency · isekaiexpansion:energy_inefficiency applies movement speed -15% total and Aether Power -25% total at level I. It also blocks normal energy checks and sprint starts, and multiplies incoming damage by 1.3 in the registered damage pipeline. It is unclearable and persistent.

Potion duration and stacking

The health and energy fatigue effects cap at 5 stacks. Their potion-use checks block another drink at the cap; fatigue is not a progressively smaller restoration multiplier.

Grade G potions apply Phantom Veil for 900 ticks (45 seconds), Aegis Ward for 1800 ticks (90 seconds), Battle Frenzy for 1200 ticks (60 seconds), and Fleetfoot for 1800 ticks (90 seconds). A repeated drink while the matching effect is active raises its amplifier up to 1. Battle Frenzy’s potion additionally requests potion-sickness damage equal to 15% of maximum health, bounded by current health minus 1 before the damage pipeline. The effect grants no life-steal modifier.
