alright fuck it, let's do something for newcuties
add yours, we can compile it later
>always craft forma, 24/7 - stockpile blueprints by doing fissures
>your early goal is rising mastery level and doing quests
>you rise mastery level by leveling unique shit to 30/40 (40 is for lich/sister/coda shit, you don't have to know what that is for now)
>generally you are free to sell all weapons you get early after you level them up to 30 to get mastery from them - most of them have superior version you can get down the line and even if they don't then they are very easy to get
>focus on getting one of 6 generalist syndicates (Hexis/Suda/Meridian/Loka/Red Veil/Perrin) to max level - your early source of play should be selling augments for ~10 plat - it's not much but it's enough for slots
>don't max lvl 10 mods - not only they usually have better archon/primed/umbra version but also it costs a shitton of credits/endo for very little return - I think lvl 7/10 is a good spot at the beginning
>don't sell frames unless you REALLY need slots - after Heart of Deimos quest you will unlock a way to get rid of unwanted non-prime frames
>there is nothing wrong in investing a single reactor/catalyst and 2-3 forma into an early weapon you like but 99% chance it has a superior version you will get later - so don't overinvest; for example pic related - boltor has better variants so if you really like boltor then know that you will replace it in the future BUT don't be afraid to invest anything - fun comes first, you don't have to suffer before getting superior version
>check this link, don't sell that shit https://wiki.warframe.com/w/Weapons_Required_as_Crafting_Ingredients
>play your fissures, fissures are meat of the game - source of prime parts - either for crafting or for trading
>when in doubt do quests
