Well, This mod has come a long way since it's inception. Be sure to read the How it Works portion to understand the difficulty adjuster. Or, you can just download it, set it to INSANE!, die, THEN come back and read it... either way. Ideally, I am trying to make Terraria more fun without adding a whole bunch of "new content." Originally, the plan was to make it so the game increased in difficulty whenever someone joined your server. That has changed, as people requested increased difficulty because the 1000000 mods out there made the game too easy. Long story short, I give you Dynamic Difficulty Please keep in mind, if you are not using a mod which increases your health, defense, or damage. I would recommend starting on Normal and moving to Hard. If you ARE using a mod which makes you overpowered... start on Hard and go from there. Hellish and INSANE! are very very very hard you WILL die. Important! Please read the How it Works section to avoid confusion! Important! How it Works Difficulty Setting When selecting one of the starting difficulties in tAPI Mod Options. NPCs are increased in strength globally, meaning they all get equally harder based on the difficulty selected Dynamic Difficulty When adjusting the difficulty dynamically the game gets harder in a way it would become harder for more players. NPCs get increased health, damage, spawn rate, spawn amount, defense, and knockback resist. Bosses get a larger increase to health, damage, and defense. They also get a boost to speed. Lastly, bosses also get some new interesting attacks and tricks to make the fights harder and more entertaining. This difficulty adjusts on a scale based on two factors: Multiplayer and the Difficulty Adjuster and can be incrementally increased for the PERFECT challenge to your play style and mod combinations. Multiplayer For every player that joins your server, the difficulty increases by 1 Difficulty Adjuster The Difficulty Adjuster simulates extra players being on the server. It can also be used in single player to increase the difficulty dynamically Difficulty Setting vs. Dynamic Difficulty The Difficulty Setting is a static increase (This can be changed in mod options after the mod has been enabled in the Mods menu) Normal: Vanilla Terraria with the Difficulty Adjuster. Allows for adjustment of the difficulty to make the game harder for extra players Hard: For those of you who like things a bit more difficult. All enemies in the game start with double health and damage: This can be further increased using the Difficulty Adjuster in game Hellish: This is where things get tricky! INSANE!: Go ahead... I dare you! Dynamic Difficulty can be used to further tweak how things act in the current difficulty setting. No longer will Terraria be too easy! Version 1.0: Released WIP Built for tAPI r13a Updated: 10/31/2014 @ 10:02pm CT (GMT -6) Current Version: 1.0 -Download- Current Features: Increased difficulty based on the number of players currently on your server. Difficulty Adjuster, a placable tile which will increase the difficulty on top of the number of players (Also works in SP, so you can increase the difficulty there) NPC critical hit chance, NPCs have a chance to critically hit you, just like you can to them: Their chance to crit also scales with difficulty Increased boss movement speed - Also scaled with difficulty, the bosses move faster as things get harder Eye of Cthulhu has a few new tricks up his sleeve! Up the difficulty and give it a shot! Eater of Worlds has a few new tricks up his sleeve as well! Starting Difficulty! Normal, Hard, Hellish, INSANE! (See Changelog for details) Skeletron has a couple new buddies to help him during battle. Careful, don't get hit! Changelog (This section is separated in to tAPI and tConfig versions. This mod has existed for a long time and the progression needed to be separated) tAPI Version 1.0 Updated for tAPI r13 Fixed Difficulty Adjuster not working in multiplayer Fixed Special NPCs not receiving updates Fixed Tile Sync Issues Fixed an issue where NPCs would receive boosts 2 - 3 times in some cases. Updated Difficulty Adjuster Tile Sprite and Frames (Thanks to @Grox The Great!) tAPI Version 0.7.5 Updated for tAPI r11 should now include different NPC variations. tAPI Version Beta 0.5.2 fixed issue which caused the Difficulty Adjuster to stop working tAPI Version Beta 0.5.1 fixed error building mod for r9 tAPI Version Beta 0.5 ported mod to tAPI and made some minor improvements small bug fix to mod options tConfig Version 2.0 Final Fixed last known bug: Difficulty adjuster now properly syncs in MP tConfig Version 1.8: Fixed a bug which would incorrectly multiply NPC stats at higher difficulties. tConfig Version 1.7: Difficulty Adjuster now properly shows the scale including the players on the server Added Mini Guardian NPC to increase the difficulty of the Skeletron fight. tConfig Version 1.6a: Fixed the Damage Multiplier for higher difficulties. Be careful though, Hellish & INSANE! still pack quite a punch. I wouldn't attempt them without friends and some serious gear. Eater of Worlds fixed, no longer obscenely difficult tConfig Version 1.6: Enhanced the Eater of Worlds, every time a part of him dies several different smaller worms come out. Careful, higher difficulties can really increase the amount of damage this boss can deal. tConfig Version 1.5: Further difficulty enhancements! Normal: Vanilla Terraria with the Difficulty Adjuster. Allows for adjustment of the difficulty to make the game harder for extra players Hard: For those of you who like things a bit more difficult. All enemies in the game start with double health and damage: This can be further increased using the Difficulty Adjuster in game Hellish: This is where things get tricky! INSANE!: Go ahead... I dare you! tConfig Version 1.4: Eye of Cthulhu has a couple new tricks up his sleeve! Randomly, he will spawn a Wandering Eye to attack you on top of the normal Servant of Cthulhu! Higher difficulty, higher chance of summoning one. Careful, at higher difficulties this can get very intense! tConfig Version 1.3: Fixed the way I handle npc.type variables Added increased speed for bosses based on difficulty tConfig Version 1.2: Fixed a bug where bosses were regarded as npcs as well, increasing their damage and defense too high Added critical hit chance for NPCs: Now the higher the difficulty, the higher chance an NPC or boss will hit you critically. Try not to get hit too often! tConfig Version 1.1: Fixed support for Multiplayer Fixed duplication of the Difficulty Adjuster Added Synchronization to the Difficulty Adjuster tile, now when one is updated they all are tConfig Version 1.0: Increased Difficulty up to 10 players Difficulty Adjuster - Allows you to simulate additional players (Useful in Single Player or when you want a greater challenge in MP) Warning: Some bosses are impossible to beat alone at higher difficulties. The challenge of tackling them with a few friends can be extremely fun to do. Also, Hellish & INSANE! difficulties will most likely require fully equipped characters to get started. Planned: Balancing for 1.2+ content Further boss enhancements Please take the time to test it out and tell me what you think! Also, keep in mind the difficulty adjustment scale may still need some tweaking - I am not sure how well the scale will ... scale especially with the new 1.2 and up content.
