Legendary familiar make easy - I hope it helps
Legendary familiar is an aberrant familiar with at least one passive legendary skill, at least one attribute equal or higher than 170 and at least one advance trait ( active or inactive ). By the way, legendary passive skills come hand in hand with advance trait. Correct me if not.
There is 3 way to get it.
- Buy from market place or shop ( if you are lucky enough )
- You have an aberrant familiar with at least one passive legendary skill and you have another familiar of same species ( ordinary or aberrant ) with at least one attribute 170 or above. You then exchange skill with 3000 platinum.
- Aberrant conversion. Make sure you use conversion stone. The one with the most passive legendary/ rare skills familiar will determine the rarity - as it will improve/ keep the number of the passive legendary / rare skill. There is 1/3 chance of that converted familiar stay the same species ( 2 of the same is 66% and 3 of the same is 100%). Passive skills are all reroll - random with so call probability. Trait are also reroll during conversion.
How to make a Savior Cat. There is a no easy way if you are not buying it straight away from the market.
Starting with a legendary familiar ( any species ), convert them with 2 aberrant kittens (2000 platinum one from NPC) , 2000 platinum and conversion stone. Do it again and again when you get your cat and savior.
Starting with a non legendary aberrant cat and convert with 2 aberrant kitten as above. When you are lucky enough - you get the savior skill. Then you buy a cat in the market with any attribute 170 or higher and do the attribute exchange.
Happy farming.
