Survival Mode (Player)

Survival Mode Is an option when you create a character. You will get debuffs, like Hunger if you haven't eaten in 45 minutes (Realtime), and Starving if you haven't eaten in 2 Hours.

Buffs:
Hunger (Stats are lowered slightly)

Starving (Stats are lowered more, and you take 1 damage every few seconds)

Full (Stats are slightly Raised)

Thirsty (Stats are lowered)

Very Thirsty (Stats are drastically lowered)

Refreshed (Stats are slightly raised)

Dark (When you are in the dark, you take 10% more damage, but move 10% Faster)

Scared (If you are in the dark to long, or fighting something you shouldn't be at the moment, your movement speed and regeneration will slow down)

The buffs from the Campfire and Honey negate some debuffs.

New stats:
Hunger (Goes down by 1 every Minute, 200 Max) You will get hungry if you haven't eaten anything in 45 minutes, and starving if you haven't eaten anything in 2 hours.

Thirst (Goes down by 1 every Second, 1,000 Max) You get thirsty if you haven't drank anything in 250 seconds, and very thirsty if you haven't drank anything in 750 seconds.

Warmth (Goes down by 1 bar underground, 2 in Snow Biome, 3 if you are frozen, and 1 during the frost moon. Goes up by 1 if you are in the desert, 2 In the lowest part of the Caverns, 2-3 next to a campfire, 4 in the Underworld, and 3 if you are on fire. Affects regeneration, movement speed, and damage taken. Max of -10 Cold, and 10 Heat.) Try to keep your heat around 0, for minimum negative effects.

Other things:
Torches burn out in 1-10 minutes.

Enemies are better at tracking/hunting you.

You have a chance to not craft things. Example: Things lower than tier 2 have a 95% chance to be crafted, Tier 3-4 have a 90% chance, 5-6 have an 85% chance, 7-9 have an 80% chance, Luminite things are always crafted, and 10-11 have a 75% chance.

Arrows have a chance break without hurting the enemy, unless they are tier 5+.

Reforging has a low chance to break things after 10 reforges.

NPCs are more helpful, and will give you free items like wood, torches, arrows, bars, or even armor pieces and weapons.

The Travelling Merchant will stay for a Terraria week to a month if you pay him 50+ Gold. If you pay him more than 1 Platinum, he will be the Asian Merchant, and will permanently stay.

Almost all weapons except for Magic and Summon have a chance to inflict Bleeding.
