Fast way to level a solo guild to 5?

[Airstrike[Zzz]]

So I'm stubborn, maybe a bit stupid. Wanting to stick it out with my solo guild, but I'm locked from using the arcane crystal until my guild is level 5. My character is level 180, I've played this game on and off for a good while, but my guild is still only level 2. Is there a way to speed this process up, or should I just cave and join an actual guild?

Hi Airstrike[Zzz]

There is only one way to increase the guild level, and that is with guild coins, i.e. by upgrading the tree of life. Each upgrade in the guild tree (not the personal tree) gives you a certain amount of XP, which then increases the guild level.
This means that the more actively you play every day, the more guild expeditions you can do = guild expeditions then give you the guild coins and exp. token. But as a solo player it will take a while to reach guild level 5, it mainly depends on the activity times, or how many guild expeditions you do every day
2 of the amulets could help: 1 amulet of exploration and amulet of greed (both increase the chance of getting more guild coins from the expeditions)
Otherwise, the more guild active members you have, the more can be done guild expedition and therefore more guild coins you can get for the guild level or you can buy one of the guild offers
