Survival skills

Athletics, Swimming, Heat Resistance, Cold Resistance, and Endurance — damage reduction formulas and GM immunity effects.

Five survival skills reduce damage from environmental hazards. All five share the same damage reduction formula, and all five grant full immunity at skill 100 (GM).

Shared damage reduction formula

The plugin uses an internal HP system where all damage is scaled by 10×. The survival skills apply compensation so that the final damage felt matches vanilla expectations at skill 0, and approaches immunity at skill 100.

base_reduction  = 0.1             // normalizes 10× internal scale to vanilla-equivalent
skill_reduction = skill × 0.9 %  // max 90 % at skill 100

final_damage = internal_damage × base_reduction × (1 − skill_reduction / 100)

Skill	Effective damage taken
0	10 % of internal (≈ vanilla)
50	5.5 % of internal
100	~1 % of internal (near-immune)

GM immunity (skill 100)

When a survival skill reaches exactly 100, the damage event is cancelled entirely:

• No damage dealt
• No screen shake
• Special effects apply (see each skill below)

Athletics

Reduces: Fall damage

Raises when: You take fall damage

Difficulty: Based on fall height (10 – 80)

Feature	Detail
Damage reduction	90 % base + skill × 0.9 %
Skill 90+	Small falls (≤ 6 blocks) have a chance to be completely negated
Skill 100 (GM)	Full immunity — no damage, no screen shake

To train Athletics you need to take fall damage. Repeatedly falling from moderate heights (3–6 blocks) gives appropriate difficulty for early gains. Taller drops are more efficient but riskier.

Swimming

Reduces: Drowning damage

Raises when: You take drowning damage

Difficulty: Based on water depth (20 – 50)

Feature	Detail
Damage reduction	90 % base + skill × 0.9 %
Air reduction	Skill / 2 % chance per tick to cancel air bubble loss
Skill 80+	Random chance to gain Water Breathing effect
Skill 100 (GM)	Full immunity — no drowning damage, no screen shake

Swimming raises only from drowning damage, not from simply being underwater or losing air bubbles. You need to actually start taking damage to earn skill gains.

Heat Resistance

Reduces: Fire and lava damage

Raises when: You take fire or lava damage

Difficulty by source:

Source	Difficulty
On fire	20
Magma block	25
Fire block	30
Lava	60

Feature	Detail
Damage reduction	90 % base + skill × 0.9 %
Fire duration	Reduced by skill
Skill 95+	Chance to extinguish yourself while on fire
Skill 100 (GM)	Full immunity — damage cancelled and any active fire is immediately extinguished

Lava in the Nether provides the highest training difficulty (60) but is extremely dangerous. Carry a Fire Resistance potion and build Heat Resistance through safer fire sources first.

Cold Resistance

Reduces: Freeze damage (from powder snow)

Raises when: You take freeze damage

Difficulty: 40 (fixed)

Feature	Detail
Damage reduction	90 % base + skill × 0.9 %
Freeze buildup	Reduced by skill
Skill 95+	Chance to break free from a frozen state
Skill 100 (GM)	Full immunity — damage cancelled and frozen state is immediately cleared

Endurance

Reduces: Suffocation damage and contact damage (cactus, berry bushes, etc.)

Raises when: You take suffocation or contact damage

Difficulty by source:

Source	Difficulty
Contact (cactus, berries)	15
Suffocation	50

Feature	Detail
Damage reduction	90 % base + skill × 0.9 %
Skill 90+	Chance to completely ignore a suffocation damage tick
Skill 100 (GM)	Full immunity — no suffocation or contact damage, no screen shake

Training summary

Skill	Best training method	Notes
Athletics	Controlled falls from moderate heights	3 – 6 blocks for early gains; higher for later
Swimming	Stay underwater until you start drowning	Depth affects difficulty
Heat Resistance	Stand in fire; approach lava carefully	Fire (difficulty 30) is safer than lava (60)
Cold Resistance	Stand in powder snow	Fixed difficulty 40 — straightforward
Endurance	Walk through cactus farms or berry bushes	Suffocation (difficulty 50) trains faster but is harder to set up safely
