Hello everyone! Sorry I'm so late to this post, I would've loved to get to it earlier.
This is my post from about 2 years ago, I'd say 99% of it still applies. There's much more to learn too!
Breeding tips:
1. In the first few generations, if you are short pet skill points you can save some points by making the combined parent resistances/health odd. Example. Male - 75 physical, Female 74 Physical, baby will have 74.5, rounded up to 75!
2. Some stats can train pretty high just by fighting. I got my CuSide to str-630 dex-128 int-162 just by afk fighting training elementals. The babies will come out with higher stats as well, and less points you'll have to spend in the future.
3. Save your points for armor and resists (level 10 unlock and level 20 unlock)! Your pets will take a lot less damage, allowing you to fight harder monsters.
4. According to patch notes, chance to breed depends on animal lore, taming, and luck, augmented by pet generation. So wear your full taming suit when breeding.
5. With some higher level pets, you will fail, a LOT. Just keep at it.
6. Remember, a greater dragon with high health and worse DNA is better for breeding than a low hp GD with good DNA, as you don't have to dump 200-300 points into HP.
7. If the pet isn't too rare, save your +1 pet level deeds.
8. At the same time, if a rare 4 breed pet has good DNA, it might be worth getting it up to higher levels with level deeds to breed them!
Taming tips:
1. Use Spellweaving spell, Ethereal Voyage on monsters that fight back. Walk off screen, invis, cast EthV, run back and spam tame pet with your taming gear equipped, with a 6 strength Spellweaving focus, you'll have plenty of time to tame it.
2. You can tame CuSide's fairly easy by putting a 1 slot animal between yourself and the cu in a tight corridor. The cu won't be able to go through you, and you can tame through the docile pet.
3. If something is too hard, you can always ask a friend to come with you and heal you nonstop while peacemaking the pet.
Pet Leveling tips:
1. High hp mobs that are easy to kill give a ton of xp. eg. rotting corpses, gauntlet bosses, etc.
2. Once you hit 10, raise your resists!
3. Once you hit 30, max out your armor!
4. If you are training an AFS or a regular fire steed, you can cast corpse skin on monsters to lower their fire resist, increasing pet damage both from melee attack and their FIRE BREATH (yes it exists)!
5. Discordance lowers resist as well.
6. If you have a weak pet, you can just have the pet hit any monster once, and kill it yourself and your pet will get the xp.
7. Wrong dungeon trammel has the best spawns to kill for leveling pets. There are two locations, one east and one west side of the first level. The juka jailers and red troll give about 10-25k xp per kill. They die pretty fast but what makes it the best pet leveling area is they re-spawn almost instantly. Contributed by Blackmamba and verified! Great xp, mobs don't hit too hard but they run, so prepare to chase them.
