An official overview of game mechanics.
Characters
Scaling all the things
There is plenty of opportunity to create absolutely crazy builds, so if minmaxing is your jam, this should scratch that itch.
Skills are your primary damage and utility. There are projectile and area of effect skills, which can be scaled through a variety of means.
Skills are autocast, so you just need to focus on looting and dodging.
Items are your primary source of stat increases. They directly affect the effectiveness of your skills, so make sure you pick ones that synergize!
Every item in the game can be equipped with an Implant. Implants are item and skill customizations, each having a unique set of powerful effects. Implants are found in chests and by killing enemies.
Implants which affect skills will only affect that particular skill, and will modify the base stats of the skill.
Implants which affect items will affect all skills, and will increase with each tier of the item. Implant effects stack multiplicatively with all other stats on the item.
For example, if you have an T1 Amplifier with an implant that gives +5% skill damage, the effective damage of that item is 1.2 * 1.05 = 1.26, NOT 1.2 + 0.05 = 1.25.
Mutagen & Mutations
is the main currency/collectible in Mutagenic. It’s primary purpose is to buy mutations for your characters, providing them powerful upgrades for each run. Mutagen can be found by killing enemies, or disassembling unwanted Implants.
Mutagen Capacity
Mutagen capacity determines how many mutations you can apply onto your character. You can increase this by spending Mutagen to purchase more capacity.
Each tier of mutation costs more than the one before it, so make sure to prioritize upgrading this!
Important
Mutations only apply to your next character playthrough, so spend it wisely!
Levels, Mutagen Scaling, and Loot Rolls
There are currently 4 base levels in Early Access, and they have the following loot settings:
- Damp Cave
Maximum tier of implant mods: T1
Mutagen Drop Multiplier: 1.0 - Wild Forest
Maximum tier of implant mods: T1
Mutagen Drop Multiplier: 2.0 - Burning Underground
Maximum tier of implant mods: T2
Mutagen Drop Multiplier: 3.0 - Endless Oasis
Maximum tier of implant mods: T3
Mutagen Drop Multiplier: 5.0
Normal enemies can drop body parts (base +5 mutagen), or a single mutagen (base +1 mutagen). These base numbers are multiplier by the level Mutagen Drop Multiplier, as noted above.
Elite enemies can also drop strong mutagen (base +5 mutagen), which are further scaled by Game Difficulty, but will stop scaling past 20 minutes.
Overview
Implants currently have 3 rarity levels, which allow the implant to roll either 1, 2, or 3 mods.
Furthermore, every mod has 3 quality tiers (T1, T2, T3) which it can roll from, higher tiers noting stronger effects. The availability of mod tiers is dependent on the level, as noted in the Levels section above.
Implant Rarity
Game Difficulty will affect the chance of dropping Implants with higher rarity. Higher difficulty means greater chance of rarer drops.
Implant Tiers
Implant tiers are all equally likely to roll, but only tiers enabled by the level settings can roll.
