You can open the Silver/Locked Chest by using magic key. You get the key’s recipe after clearing Grandshelt Castles. To create the key you need
 Screamroot: Obtained from trophies reward. You can find it from Minituar (from any exploration map) as a drops, but I never found it after playing this games for about a month….. so let’s say that it’s super rare enemies…
 Fine Alcryst: you have a chance to obtain this item every time you craft an ability. Reddit says that it has 20% chance of appearing but I find it that it’s lower than that. And even if it has 100% rate, the problem still lies on screamroot.
Other ways to obtain magic key:
 Exchange your lapis for them (you can find it on the shop); not recommended
 Wait for an extra event that gives you discount on magic key (Example: Summer Special package which run from 11 – 19 August 2016, the package gives you 1 rare tickets, magic key, elixir, and Megacites for only 300 Lapis).
You can find my list of recommendation below.
Worst = avoid this……
Bad = Bad, but still can be tolerated and you may find it useful on very rare occassion/in the beginning of the game
Ok = Nice to have right now, but we may see an upgrade on the future, so you may want to save the key for later.
Nice = This is very nice to have, most of these are passive abilities.

Remember that it’s my thought, you may have different opinion about the treasures. Few questions that might appear on your mind.
Why I thought [Insert element here] Blade, bad?
First they do the hybrid damage, I don’t know the exact calculation of the damage, but they take a little bit from your magic and a little bit from your Atk Parameter. The result is not so high damage even after you attack the enemy that weak against it. You’re better with other skills (Most of good attackers have unmitigated damage skill, barrage, and other skills which are more powerful than these).
Why I say [Insert status recovery spell] Ok?
First spells like vox, paralyna has low lvl White magic compatibility, which mean many characters can equip them. They’re really situational though, however most of the hard bosses can inflict you with some kind of abnormality. Esuna is very hard to get (Maria Trust Master).
