DragonSky Lab Upgrades:

(# / #) indicates the max level for obsidian and gem research

  1. Increase the Max number of dragons on-screen (Normal) (2/1): Basically, buy it, you can also use normal dragons as meatshields when you are pushing stages.
  2. Reduce Hatching Time (5/5): At max level, you will have a 5.5s hatch time. Can be further upgraded to 4.5secs when you hit lvl288
  3. Double Evolution Fusion (5/10): Your fusions have a chance to have +2 tier, useful till Tier-5, e.g. T5 + T5 = T7
  4. Hatch Tier 2 Dragon (10/10): Gives you a chance of having T2 dragon from hatching, gives you free hatches at the end of the line.
  5. Increase Max Egg capacity (5/5): Useful for F2P but not really that useful for Autoplay users, if you are an autoplay user skip this.
  6. Increase Number of Dragons on-screen (Elite) (2/2): By this time, you can focus on getting other elites, buy this to expand your elite to 6slots.
  7. Skip Start Stage 1 (40/40): Can be taken before you take “Additional number of the elite on-screen” when you are still focusing on 3 mains.
  8. Increase [Rush] Max Count (3/3): Use your rush counts on later stages of your push, as it is much harder than early and will save you time.
  9. Increase the number of [Rush] stages (50/35): Increases the # of stage you can rush
  10. Additional [Rush] Stages (55/40): Increases the # of stage you can rush
  11. Reduce [Rush[ Cooldown (55/55): Reduces cooldown for rush, P.S. extremely expensive to level this up
  12. Skip Start Stage 2 (250/200): Can be taken at any time of your upgrades as the early levels are cheap but later levels are extremely expensive

  • Take other upgrades at your own discretion
  • You can take Increase [Rush] Max Count earlier depending on your game activity if you check it every 3-4hours no need to upgrade earlier, but if busy with work or stuffs, definitely take it earlier for more rush opportunities
  • It is advisable to skip some part if it costs too much, to balance out the cost/upgrade on all upgrades
