DPS monsterling strategy
I think the best strategy is first building 3 universal monsterlings with 2 skills each.
Seeing that we will be using always the correct element after floor 11 in rift we can skip Amon and use Ice Fist dude instead for a permanent 11% crit.
So the best initial universal monsterlings imo would be: Gulgak + Ice Fist Dude/Amon + Scar
Initially I will get the three of them with: Skill cd + Boss damage
The Gulgak is an universal monsterling that will be used until we finished with the other 2 monsterlings with 4 skills and then we will change it for an specialized elemental monsterling like Duoxini for fire, Moon Shadow Lupe or better for each element... The Gulgak can be used later on by the other characters of the team.
Now let's go with the skills:
Imo we need one monsterling with a crit % skill, adding a 5% and getting us closer to the 75%, we would need 3 armor pieces with 11.7 crit and one with 11.4 for a perfect 75% with this skill on one pet that you will always use, so scar or icefist/amon.
Elemental weakness is not needed in the 3 pets, specially when a ton of elemental monsterlings buff this stat and the cap is 200%, so this is my plan:
Gulgak as a link: will stay with skill cd + boss, will not get 4 skills till far far later. Won't even make it gold for a long time as well if ever...
Scar: Boss damage + skill cd + Crit% + ATK%
Ice Fist dude or Amon: Boss damage + skill cd + ATK% + Elemental Weakness. I have an amon but will make a gold atk%+elemental weakness ice fist dude and fuse both and use whatever it becomes. New players if you don't have Amon, you might want to go Ice Fist directly, far easier to get as well.
Some people say that skill cd is not needed in 3 monsterlings, but I don't know if the next dpss will need it or not and I can modify it by changing the skills of the specialized elemental monsterling later on. So for now will go for x3 skill cd.
Once I have this, it is time to start with the elemental ones, again would probably go with the same skill combination than ice fist dude, starting with a boss + skill cd for each element and once that we get more gold upgrade stones we can start finishing them.
Monsterlings for support and destroyer are not that important so you should not be wasting gold nor purple upgrade stones on them, if you want a lupe for your destroyer just get a purple lupe fusing lupe + purple random monsterling, then make a monsterling with neutralization + damage to boss and fuse them together, then pray to get a lupe, if not rinse and repeat.
Once you get the purple lupe with 2 yellow skills just get more plain purple lupes and try to get gold lupe with 2 skills by fusing purple lupes over and over. This require a ton of purple monsterlings but is faster than waiting a year till you get a gold upgrade stone that you can waste in your destroyer. Current best monsterlings for destroyer imo: Hahnul as link, Lupe and golden fist if you plan to get every destroyer, that I will not, so I will probably go with orange cappy instead of golden fist dude. f2ps must focus on dpss or at least is what I will do till I have one event dps for each element, Narae, Flare, Yeonhwa and Francis will have to work overtime till I have free currency for destroyers or supports...
Support monsterlings are not very good rn, I will care about them after Narae is here and I see what new monsterlings are coming... Can foresee that Fiend might be bis for her as link if the totem breaks her bubbles with fire attacks don't know if that works or not yet. I have already a weapon for Narae that buffs shield hp and heals 15% of her hp to team members by using her special skill (granting shield) every 30secs called Celestial Halo of Protection (at max dupes).
What do you think? Are your plans different?
