==Due to real life circumstances, this guide will be on hold for the time being. I apologise for the delay.
This guide is a work in progress. The information in the guide as of right now is accurate, but some sections are incomplete. There is also no actual format or flow at the moment==
Here are a few important points to keep in mind (they'll be repeated later on, but this list is here as a sort of "quick answer" to common questions)
- pets can be purchased at home shop starting at level 5
- there is only 1 pet available currently
- pet academy unlocks at level 5
- pets cannot be removed from an active action (ie. if it's currently on Prism Bridge, currently harvesting/creating resources, if there are Eidolons training/studying in training grounds/pet academy respectively for pets being used as principle/principal)
- you can ignore the "(Must upgrade to middle school/university/college)" text, as that is done automatically when you have a pet study a skill slot multiple times
- having a pet study will replace the selected skill with a random skill that is 1 level higher, stopping at college level -- if you have a new Pine Nut pet and have it study it once, then it will learn a random skill at the elementary school level. Training that slot a second time will cause it to learn a random skill from the middle school pool of skills
Once your house reaches level 5, you'll be able to purchase pets from the Pet Shop. Currently, there is only 1 pet available: Pine nut. They cost 1000 Town Coins each and you can purchase up to 2 a day.
Pets have 4 stages of evolution: grey (1), green (2), blue (3), and purple (4). Evolving a pet increases the effectiveness of its base skill and the number of skills that it can learn.
Evolving pets is done from the Home Pets interface. To evolve a pet, it costs 20 town coins and you need to sacrifice "spare" pets that are the same kind and level as the pet that you're trying to evolve. i.e. if you want to evolve a stage 2 Pine Nut, then you'll need to have 5 other stage 2 Pine Nuts that aren't currently assigned to an activity. In case the bolded and underlined text wasn't enough, you WILL be losing the pets that are being sacrificed, which leads me to my next point.
In terms of which spare pets are sacrificed, it's hit and miss. Your safest bet is to assign any spare-status pets that you don't want to lose to a random building. There have been cases where even the selected pet is used as a sacrifice.
Pets can be assigned to various buildings/structures to assist with the building's actions so long as the assigned pet has a corresponding skill. This means that assigning a pet with prism bridge skills as a principle to training grounds is pointless.
- for the factory, blacksmith, sawmill, and weapons factory buildings, a pet can be assigned to each open slot in them
- a pet can be assigned to the training ground as principle and its skills will affect the training of all Eidolons there
- a pet can be assigned to the pet academy as a principal and its skills will affect the studying of all pets there
- for prism bridge, up to 5 pets can be sent out (the number of pets increases with your house level)
Unlocks automatically once your house reaches level 5, you'll be able to train your pets to learn skills. When you click the Pet Academy icon, a new window will open with 2 tabs: the Further Studies tab (this is where you'll select which pet and which skill slot you'll train) and the Course tab (where you select the principal and view previously unlocked skills).
You will see a list of all of the pets that you currently have. From here, you can select which skill slot on a pet that you want to level up. You can have up to 2 pets study and each study attempt costs 10 town coins regardless of how many times the pet has studied before. There is also the option to lock a skill for 10 diamonds if the skill is not college level. This means that if you get a skill that you want early on, you can lock the skill so that it won't change when you level up the skill slot. Note: the skill will unlock once you train it again (i.e. if you have Gold Rush lvl 1, lock it, and then train it to Gold Rush lvl 2, then you'll have to lock it again before training it or you will get a random skill.)
You can select a pet to be Principal for the Pet Academy. The skill(s) that the principal has will affect all pets that are currently studying, so you'll ideally want to select a pet that has skills that reduce study time or cost as principal. Note that while a pet is a principal, it can't be selected for any other activity in your home except for studying within Pet Academy and you cannot remove a pet as principal if there are pets currently studying in the Pet Academy.
Levels of Training
You'll see 4 additional sections below the Principal: Elementary school, Middle school, University, and College. If you've never had a pet learn a skill before at that level, then it will appear greyed out under that level. The transition from elementary school to the higher levels is done automatically when you train a pet's skill slot multiple-- training a pet's skill slot for the first time gives it a skill in the elementary school skill pool, training it again afterwards will give it a random skill in the middle school skill pool, and this extends to university and college. tl;dr: you only need to have a pet study 4 times (per skill slot) to reach college rank.
