ive always like the idea of passive talents in a game and while playing grounded and grounded 2, i thought they would be nice to have in here as well. passive mutations would always be in effect and require greater steps to unlock. its a way to reward the little things in game we do, by rewarding continued effort. for instance:
harvester mutation:
unlock:
Bust, or chop down X(for instance 100, 500, 1000, 2500, 5000) number of pebbles/grass/weeds/shells/acorns etc.
result:
10% increased tool swing speed for harvesting per level, 2% chance to instantly chop down/bust item per level. 5 levels
Leg day mutation:
unlock:
travel X meters(1000, 5000, 10000, 25000, 50000)
result:
stamina exhaustion recovery effect gained from sprinting reduced by 10% per level(only from sprinting so this doesnt effect combat stamina exertion). 5% movement speed gain per level. 5 levels
insomniac mutation:
unlock:
spend x(2, 5, 10, 15, 25) number of days consecutively without dying or sleeping, denying yourself that refreshed feeling.
result:
vision at night grows easier. can see in a radius arround you as if you were holding a torch. 2m radius per level. 5 levels
Hardened warrior:
unlock:
receive X(1000, 5000, 10000, 25000, 50000) ammount of hp damage from direct damage sources(non-player)
result:
innate damage reduction, applied before armor defense reduction, 2% per level. 5 levels.
Smithy mutation:
unlock:
repair x(20, 50, 100, 250, 500) number of items(gear) with at least half durability missing.
result:
repairing takes 1 less random item per level, minimum required repair:1 item. 5% chance per level to get free repair. 5 levels
obviously numbers can be tweaked based on what the devs think is too high or too low, but i believe passives should require work to obtain. also these were just the ones i came up with and im sure theres other good ones.
