The cost not doubles, but incrases by cost of 1st tier. That is because initial cost of upgrade goes up by 1, so lets say we have T0 and hitpoints initial cost is 1, in that case we spend 62.51M points to cap it. When we go up tier its initial cost raises to 2, and final cost is 125.02M points. Well, it doubled, but let's go on. on T2 its initial cost is 3, and final cost is 187.53M points. See? Its just incrasing by cost of 1st tier. To calculate how many points you need to max blueprint, use ((4.85G+0.01G[that one for safety]))*(tier+1)), hope that helps a bit.

So I need a CLEAR answer to this: Can you level up your blueprint tier without negative impact on missions/challenges? Do the BP limits adjust depending on your BP tier or not?

You'll still get damage from lower tiers. And if i'm wrong, Challenge mode completly ignores this rule.

how do you know if its better to go up to tougher Tiers or use new bounds and let the round run longer? Also, if i have a max blueprint. Is the only way to get stronger,by adding Damage/HP techs? If so, how do you handle high tier cubes? Cause a max blueprint onyl gets you so far. What is the formula for tiers and new bound? On insane is it always 3290 Waves to get to the next tier? I am thinking its better to not put any blue cubes into new bounds as you tier. Then as you get to the cube tier that is equal to your blue print tier, buy it up for white cubes in game.

if you tier up your BP do you lose ALL blue pieces or just the ones spent?

only the ones used in that blueprint and only the one blueprint goes up in tier

> Also, the higher tier of enemies you fight, the more special resoursces you get. To be accurate, you gain 75% boost every tier, that is addition, not multiplication. Tier 100 enemies give a base special resource boost of 75% * 100 = 7,500% boost. It is totally incorrect (at least now). I compared BP Tier1 and BP Tier 5 on highest levels (when enemy has about 1e300) stats, and got the same SR per second (about 5e8). If you were right, i should get about `5e8 * ( 1 + 4 * 0.75) = 4x boost`. But It is not so, there is no boost at all, or it is much less 75%, may be 0.75%, i.e. 100 times less, i will check on higher tiers.

Now I have tier11. and wave compression 11. And I can confirm one more time there is no income or waves per minute increase between tier5 and tier 11. But I noticed that each new BPT costs x1.0825 more then previous. And 1.08 ^ 100 (to reach TT) ~= 2800. So at income 1e10 SR per second I need 96 maining hours to get SRs for upgrade from BPT99 to BPT100. Update: I checked the situation on https://www.fs-studios.com/games/perfecttower/ and there the situation is even worse. No SRs or gems for new tier mobs at all. And 1.5x cost for next BPT level.

I already checked it. Some people say that WC 11 is bad. But my "Information and Stats" window (key 8) says that It is better then 10 for me (more SRsPM, Gems PM, WPM). Is this info contains a bug? May be my computer is strong enough to correctly handle WC11, idk. ======== As you said: >Temple upgrades, enemy tier AND waves (as in, waves in an enemy tier, the HP was actually false since 0% newbounds 3,200 is the same as 100% newbounds 3,200 where the enemies are the same tier, but different wave number inside that tier), wave number (total waves in the run itself), WPM, game speed, if the game is in the background or not, utility upgrades, town tier boosts, stats and info page's achievements AND black cubes spent, watching ads, HQ SR factor, factory SR interval thing. > Why is my SR going low all of a sudden? > It's probably due to enemies tiering up, for while you get more SR from enemy tiers, when they are freshly tiered, they have less tier waves, and therefore less SR at that point. Not to mention that when an enemy tiers up they are slow and don't reach the tower as quickly, so that would also be why you get less SR/s randomly. =========== I have maxed temple upgrades. And now I have WC8, and 3.4e9 SRs Per seconds, 440 Waves Per minute. For now I have 14.6 Special Resources Factor in HQ. (next costs 7.55e6 dark-blue cubes). If I understand correctly you think that BPT Tier and Wave number will give some SRs income increase. But I checked it from BPT1 till BPT11 and from wave 53000 till wave 250000, and did not notice any changes. But noticed cost increasing of each my BPT. So I have no idea how to have really huge SRs boost, like on your screenshots. Are you sure that such values are possible without Town Tier up? Could you give me please a recipe what to do to boost SRs. :) Is it just BPTiering up and increase wave numbers, and may be use low NB to have this misterious 75% boost (and not confirmed by my previous game) from mobs BPT?

Update. Now I started the game after reset. And confirm that WC5 is a bit better then WC6. Also, now I have WC 10 and fantastic 1.75k WPM %) Update2: Now I confirm that WC11 have only 200-300 WPM %) So probably the whole browser cleaning affected smth. I hope this also will affect BPTier bounty from mobs. @jeremyx, thank you, without your post I would not start play the game again ) update3: I was wrong about BPTier cost. It is no always x1.0825. I starts from 1.5 and drastically decreased from BPT till BPT, like tier1: 9.7e9 tier2: 1.45e10 .... tier10: 5.33e10 tier11: 5.82e10 update4: For mobs with BPTier 1 and HP about xe290 I still gain 3e10 SR Per Second (1.8k WPM), so for now there is no those 75% ( Also wave number was 111100 against 52000 and this did not help also ( BPT2 and HP about e290 - the same 3.15e10 SR Per Second (1.84k WPM), round 169100 - also did not help. I will check on higher BPTs...but now I have no idea how to achieve those huge incomes from jeremyx's screenshots. Further I will hope that gain from mob BPT is exponential, say 1.01 for BPTier 1 - 2, and 1.05 for BPTier 3, and so one..

How I am BPTier 96 and made an experiment at round number about 3.5e6. I set different NB and get mobs tiers from 63 till 96. And there is no difference in SRs per minute at the same HP. I also made an experiment (using NB) to compare SRs PM from mobs with the same tier and HP but at different rounds. And I can say that round number increases income. So now I am pretty sure that income does not depend on mob's tier. But it depends on mobs HP and current round number. So the key for income, IMHO, is to max NB and max rounds. Words about 75% increasing with mobs tier - are wrong. And there is no sense in NB trick now.

Update: I finally understood why there is no income increase with mob Tiers (not taking into account wave number). Indeed there is income from mob tier like (1 + 0.75 x tier), but for reward for compression there is divisor like: 125 x (1 + tier) which overkills all this reward. So these two formulas become just a constant 0.006. And enemy tier just does not affect income. Only two things do affect income: wave number (as log(waveNumber, 1.6)) and enemy HP (as HP/20). See my conversation with XmmmX99 in his page in the game: https://www.kongregate.com/accounts/XmmmX99

NB trick does not work anymore (at least when compresstion is enabled). Cause it affects divisor also. There is no boost on wive number inside enemy tier, only HP matters. Say if you achive the same HP at the less wave - you will be given the same income. Stop listening to NTW, seems like his data is pretty outdated :) Why on Earth we need to listen somebody, all means for experiments in our hands. If experiment denied someone knowledge, I will believe ~to my eyes~ to experiment.
