So Leo, how do you personally gain a bunch of Training to get the tp? Do you merge3 pets into 1, then 3 more done like that into your pet you wish to level? or what? It costs a lot to get 2500 Training (What's required for 500 tp) in eggs

.
50 training from normal egg, 100 training from rune egg. I chain merge at least 50 pets a day into my pet to level up 1 passive every day.
It's "only" 50 golden eggs though, +10 for the 5 potions, or 60.
'Course, in retrospect, 200 golden eggs fed directly into his pet would probably have leveled it more than once, so you're probably right about chain combining pets. That's still an awefully expensive prospect, but certainly explains why so many runics are all being bought by the same person of so many different levels. (may not be you, but it's probably somebody doing that same idea.. somebody whose also buying Golden Eggs.. careful there whomever)
Not feeding any golden eggs. Chain merge FTW. Its actually not that hard to do, just filter AH using AdvAH and you can find all the pets necessary. Also, if you only use pets that are your pet's level-1, you can't ever lose your pet. Since merging must go into the higher level pet, you can safely guarantee you will never accidentally feed your pet into a trash pet.
But I am buying golden eggs to turn training into TP.
By training I assume you mean merging (without leveling).
No, I still mean training. You use merging to get training, but use training to get TP. You could use food to get training as well. Either way, training is best resource for TP.
But 2000 TP is 10000 training points, even multi training thats seems like a lot with just 3 slots. Unless youre feeding them golden eggs on top of it. Or there is some other trick to gaiing training points that I dont see.
10k training so far seems about right since I've done it 4 times now over past 4 days.
edit, ahh never mind you can flip flop the eggs around and not necessarily have to merge your first 3 with the main pet. So you merge 3 level 3 into a level 4, then introduce a level 5 and then merge that level 4 into the 5. Then merge 2 more low levels into the 5 and the go back the other way. Could have a perpetual ladder as long as that pet doesnt get higher than the main.
That is the trick.
Hmm might be loyalty based. I havent bought the potions to raise loyalty above the base level on most of my stuff. But we have 61, 74, and 86 as possible TP gains per level. So looks like the typical round up on one and round down on the other scenario. Will check today and see it if makes a difference.
It isn't loyalty based. View following SS of my pet leveling. (Taken a few days ago)
If I knew then what I did now about leveling, I would have raised my pet's aptitude first before rushing to level it. Oh well... I'm prepared now, current 88.77 aptitude.
