Tips/Strategies:

1. Hoard your citrus teas

2. If you're at least 39,100cp, I recommend farming Rockskin Boars and Erekhantus monsters which gives you access to not only Voidsent eyes but also an Eternal Ring.

3. Ensure that Northeast Kamasylvia main quests are complete to get access to future Everfrost events.

4. Aim for primal imprints with high burns, this will make the farming faster.

6. Look out for fish icons on the map. Fishing in Everfrost gives you crystal smelt which is needed to cook fried crystal smelt. This food will give you 1 void eye per week. You can get the quest from Baturnil in Snowstorm Guard Post. 

7. Life Plus buff can increase the stored citrus tea time by 5 hours. 

8. Mercenary board gives 1 hour citrus tea every week when you complete it's 3 quests.

9. Search youtube to find easily all Knowledge locations which provides cp and other important stats for your characters

That's all I know so far! Hope this is helpful. =)
