The trouble is the game has competitive elements

That means without energy you would be competing against people who literally have their pc's going 24/7

That still happens but it would be even worse

I don't know about others, but the further in, the less energy seems to impact me.  Right now I have about 40K energy, though I tend to only do my daily quests most days, and then burn through a couple of thousand energy for key events or tournaments.

There are so many sources of free energy in the game right now.  Significantly more than 12 odd months ago.

Ok, so, since i'm a relatively newer player, can you tell me how to get about 40K energy mostly doing dailies? (not being sarcastic, but I don't see how)

Thanks.

For the Tournaments and other competitive events I agree. But, for just regular play for dailies and to level up , wether it be postions or scrolls, or other, I don't .

Only doing dailies.

7 campaign missions, 7 x 8 = 54 energy. 

Getting 3 artifacts from dungeopns, 3 lv 20 dungeons, 3 x 18 energy = 54. 

Total of 108 energy used per day. Rewards from doing all missions is 310 energy*, surplus enregy 202 per day. 

* When your account level is high enough to have the maximum of 130 base energy. You get 50 flat energy and 2 potions from doing all missions.

Thank you Skadi. I'm only at 128 base energy right now, which is why I obviously don't see that. I look forward to leveling uo to that.

Legit I thought you were talking about the amount of physical energy required to play this game :/

I don't think the difference between 128 and 130 base energy is relevant for this. 

Anyway, there is a downside in accumulating more than the base energy, you don't benefit from the natural regenartion anymore.

To add to what Skadi has already mentioned, there is a natural energy regeneration per day that people who keep their energy at 0 are able to benefit from.

But in addition to that, there are other areas such as:

• Classic arena tournament rewards (150 energy per tournament, every second week)
• Tag team tournament rewards (300 energy per tournament, every second week)
• Clan shop (1000 energy every second week.  There's a 50/50 chance of energy or chickens in the clan shop each week, so you might get 4 weeks in a row of 1000 energy, or you might get chickens, but it averages out)
• Artifact enhancement events also provide energy at low spend.  You can just take a few artifacts to level 12 for minimal silver cost and get the energy rewards.  I think you can get about 150 or so, every 2 weeks
• Daily logins - At the 270 day repeating you can get 1000 energy a month.  Prior to the 270 day though it is a bit more random, but every month has energy in it.  For example, in the 60 day bracket there is 2000 energy.  In the 90 day bracket there is 2500 energy
• The playtime rewards that reset each day has a full energy at 60 minutes
• The free gift from the shop also provides a full energy refill.  This usually cycles out every second day or so. Note that for these will go into your inbox and have a 99 expiration timer on them.  It is usually better to keep these for emergencies
• Once you start progressing in doom tower, you will start to get consistent energy rewards every 10 floors
• Fusion Warmup event which happens once a month also has a batch of free energy for cheap, even if you don't plan on doing the fusion event.

There are other non-reoccuring energy sources as well, including promo codes that usually have energy and are released sometimes once a month, plus free gifts for holidays or anniverseries.  Early game, you will get a lot of energy from missions, challenges, Campaign rewards and Faction Wars rewards.  

I feel like I am missing some sources, and while each individual source isn't much they do add up.  I am usually busy with work during the week so I do the bare minimum, and by the end of the week I have usually accumulated a decent 3K energy from passive playing.

I also don't use gems much anymore, so I have about 12K gems sitting there doing nothing, which I could use to buy full energy refills if I really need to.

Thanks all for the feed back. It is most helpful.

Happy Raiding!
