So, I've seen the exp guide written here, without the person really knowing how exp, leveling and etc works. I guess I'll just do a full fledge guide on how to feed effectively and efficiently. *** Dividing line *** Firstly, the exp leveling chart. Resource: http://zh.pad.wikia.com/wiki/宠物升级经验表 You'll see that the exp curve increases exponentially for all the monsters. There are basically 6 types of exp curves. 1.) 1mil 2.) 1.5mil 3.) 2mil 4.) 2.5mil 5.) 3mil 6.) 4mil It gets increasingly harder to level up as the levels reach higher. Monsters images are there, so if you cannot read Chinese, use the images to look through the tables and see what category your monsters belongs to. From there on, with some subtracting, you'll be able to calculate how much EXP is needed to level up your monster without overfeeding. I hope I do not need to teach you guys now to use the chart. Just in case, here are the translations. 等级: Level 总共经验: Cumulative experience 升到下级: Experience required to level up *** Dividing line*** Next, the exp which the monsters provide. Resource: http://zh.pad.wikia.com/wiki/宠物一览表 Each monster will provide a fixed amount of exp per level, and the amount gain is linear. From the wiki link given, you'll be shown all the monsters in the game. Just click on the ones you are interested in and...... You should see this. See the boxed up part? That shows the amount of EXP it will feed per level. Or in another words, exp per level ratio. Now, we are looking at 600exp/lvl for Penguin dragons, which works out to 6000exp of feeding material at level 10. Now that matches with what we know in game. Use that to check out the exp/lvl ratio of the different monsters to decide on which monsters you'll want to use to feed. *** Dividing Line *** How to Efficient feeding: Technical Dungeons, Tier one stages Lets take a look at what drops there. Penguins: 600exp/lvl, 1mil exp curve. Only requires exp of 2600 to lvl up from lvl 2 to lvl 10. Can be evolved for even higher exp gains, but good enough at lvl 10. Stage 2 Orges: 412.5exp/lvl, 1.5mil exp curve. Offers about 1250 exp at it's lvl 3 drop. Great as secondary sacrifices outside of penguins. Stage 2 Devils: Exactly the same as the Orges. Since there are no light and dark orges, they will be your main food. Chimeras: 400exp/lvl. 2mil exp curve. Has no read purpose other than to feed 1 of that with another devil/orge to max up your Penguins. Tier 2 Crystal Monsters: 262.5exp/lvl, 1mil exp curve. Offers about 1310 exp at the lvl 5 drop. Too costly to feed compared to Chimeras with a lousier ratio, so use it to feed Devils or Penguins instead. Scale it up accordingly for the light and dark technical dungeons. For the 3 colored elements, you'll want to focus on Penguins and Devils/Orges. For light and dark, you'll be focusing mainly on Devils. For penguins, it's pretty straightforward. Make sure you feed more than 2.6k worth of exp each time to save your gold usage. Not knowing what to do with those low leveled metal dragons? Use three of those for the Penguins. Devils, you'll want to feed 3 ~ 5 monsters together at once, and after that it's not wise to feed anymore. Dump your Orges, other Devils and Crystal Monsters on them, and they should hit somewhere around level 11 ~ 13. One thing worth taking note, if you're doing hell dungeons which drops high leveled stage 2 Devils, you might want to use them straight away as food for your main monsters, since they offer a decent amount of exp. *** Dividing Line *** That's all. It's not too hard.
