New player. Should I drop all "trash" items from inventory?

[Potato]

Hello, I'm new to this game. My imperssion so far is very good, graphics and combat is great but one thing bother me is that unlike other RPG I played, after complete a quest you are reward with item or armor, weapons which you can equip or sell/ drop. This game give me a lots of Coin, Seal, Box...etc which I don't know what usage for and they can't be sell. I keep getting full inventory message all the time. Should I just drop them all?

Another question is I'm getting a lots of black crystal. Should I save them to use on better armor later game or just use right away?

if u have enough contribution points you can get more storage space in a city.
go to the world map klick the symbol of the city u are in or the one u use most close the inventory window that pops up^^ and u should see some blue and grey colored lillte buildings.
u can klick a blue one and look if they offer storage space. and buy it to icrease it.

i would sell the trash u have with u pumpking beethingy thooth the kobold thing honey all the stuff the mobs drop some of them can be exchanged. right klick and npc points u to the locaion.
hope that helps a little^^

Learn to right-click.
Then right-click again, also reading comes in handy.

Kidding aside, but actually not.
Trash loot announces itself very clearly by telling you to sell it to vendors, almost everything else is usefull to very important.
Open your map and do the tutorial that should pop up there to find out how to invest your contribution points.

A quick tip, get the farm cart at the stable manager in Heidel and park it in the stable, free inventory slots.

Thank you. What tutorial are you talking about cause I don't see any.
And what about these event coin and seal? Is it worth collecting or should I just drop it all to free inventory slot. I already purchase a house storage but have to constantly travel to city after done a fews quest just to storage items is too much of a hassle.

You probably ran away from your introductory Black spirit quests in Olvia and it´s stuck there.
Go back and finish that, BS quests lead to bosses and you get free inventory slots and gear that way.
Also open your pearl inventory and use the 7 day value pack to get more inventory for 7 days.

The shaktu seal coin is the most valuable thing in your inventory. Put it safely in storage, like the gold.

Drop the house storage, it´s useless and just steals your meager CP, buy houses with it that give bonus storage space instead.
REALLY just look up a guide on youtube, tons of those out there.

....buy houses with it that give bonus storage space instead.
Isn't that the same thing? I bough a house that give bonus inventory slot to storage keeper in town. Do you mean the residence house with storage chest in it?.

you'll be wishin u had em later. A couple months of shakatu coins = boss weapon, and 20 troupe coins = the ability to repair said boss weapons.
