Log-in Bonus
They go into your account wallet so you don’t actually lose them until you spend them. You can not open any of those daily chests and you will not lose them. I think after five they will automically go to your character’s inventory.
You should open all the login bonus packages as you get them
Yes, they are huge boosts for new players & there’s sometimes decent benefit in opening them sooner rather than later. You won’t miss anything by taking advantage of them.
Eventually, you’ll find specific uses for specific items and might (or might not) want to save particular containers. Wait until you find those special uses before worrying about it.
The sole except is that you have to choose the reward from Day 28. That’s a while from now, so you have time to ask about it later. As a rule of thumb, for new players, I strongly recommend the laurel reward — login bonuses are the only way to build up this currency. so for the first month or six, it’s the most useful option in my opinion.
Welcome to Tyria.
You don’t really have to choose the Day 28 reward; you can just put the Chest in storage. I have something like 15 or 20 in the bank, as I haven’t decided which reward I want.
