If you are super new, make sure you get get your links done + level up your main character that you farm MP with so you can 1HKO mobs in MP maps. As others have said, in our server, MP farming is the fast way to progress. For example, if you choose to donate around 1.5k-2k DP (3.75 bil to 4.8 bil) will get you enough mesos to funds MP farming.
I. 1k DP to get 2.5b mesos (more or less depend on market) and use those funds to invest into MP farming.
1. Use that to buy drop rate familiars (cheapest one is pigs (30mil -90mil for 3), spiders (120m-210m for 3). Having both sets will allow you to farm at MP or whatever for 2.5 hour straight. If you farm at MP, as other said, you can earn 1b+ mesos per hour.
2. To prepare for MP farming, you will need %drop rate. Our server has 600% drop rate cap. So with 2x drop card (get from Vote Points) and familiars card bonus (mentioned in 1.), you will need total
8 lines of % drop rate. You can buy those items then use
red cube to scrolled or
buy prescrolled with % drop rate main potential. You can take your time acquiring these items in Auction House. I have included some estimate prices below.
a. 2 rings (tempest, silver blossom) for around 200mil -300mil each,
b. face accessory (onyx gum-150mil),
c. eye accessory (aquatic -150mil or less),
d. 2 pendants (like stupid chaos horntain 150mil or less),
e. belt, shoulder etc at similar price
II. Save 500dp to buy your own pvac (150dp for 24h one), sell them when you done using.
There are also other methods that can help you get started without DP donation need: you can farm at elite aliens to get time coin (sell bpot for 360m per stack) until you acquired enough funds to do MP as stated above. I have included a guide with different farming methods for your reviews.
