So everybody who was complaining about tamas, great job. Check PDX to see what y'all have unleashed with your complaining. (I'm looking at you cmd. cool and Matsy)
I dunno why anyone would try to feed Baby Tamas. Srz, their evo mats aren't even hard to get. With the exception of Gold Dragons, which you have to wait for, but they practically drop at every floor.
If you have stones to spend for stamina refills, I'm sure you have stones for monster boxes where you could just farm evo mats and fill your boxes with it.
I'm already overflowing with evo mats for Baby Tamas right now, even my Gold Dragons has filled 70+ spaces already, and a shit-ton of Dragon Fruits from farming at Tower to the Sky x1.5, Thursday Dungeon, and Evo rushes. Why I have a lot? 'Cause I already evo'd all of my monsters that needs to be evo'ing with the Dragon Fruit.
As for me trying to awaken monsters. I don't necessarily awaken all of my monsters with Tamadras. Rather, easy farmable monsters, I awaken them with themselves. Eg. Mystic Knights.
You might think it's time consuming, but it's really not. If you already have max most of your main monsters, you probably have other monsters that aren't even leveled yet. There are days when you don't want to do some Special Dungeon, or can't. Instead, the only thing you can do to optimize your stamina is to farm at a Normal Tier 5 - 6 Dungeon that has x1.5 rate. So, you farm for: evo mats, monster fodder, +eggs*, and Rank Exp. Practically you're hitting four* birds with one stone. Assuming you've already maxed your main monsters, all those fodder monsters has to go somewhere, which is to your latter monsters. It'd be a waste not feeding them. You don't need to consume time on just one monster at a time, when you can just level them up with the corresponding dungeon that has x1.5 that day, and do another one that has a x1.5 the next day, and cycle.
I've saved a lot of Tamadras with this, and I haven't even used a lot of the free Tamadras you get from events. Most of them are sitting in my mailbox, unopened. With the oldest from 104 days ago.

I only use Tamadras on non-farmable monsters, like REM monsters, or high-exp max monsters like the Two Heroes, Cu Chu and Seig, farmable Gods, etc.
I already max awoken all my Ripper Dragons, and Mystic Knights, except Kamui, which is really hard to get, since he has no solo dungeon. 2/3 Awoken.
Ofc this works efficiently for Non-IAPs like me, or IAPs who don't like to spend much money.
If there's people who don't wanna get into this much trouble, then spend away. 50% chance of awakening is still low though.
What I would like is an easier way to get +eggs. Heck, even buy them if I'd want. Can't believe it took me 130+ days to hypermax Lu Bu(180+ days since I started playing, only at 50+ days I started feeding him +eggs).
