Lowest IV you evolve/power up dratini/dragonite

86% +

And tbh I think I would atleast consider powering any dragonite I just spent 125 candy on, regardless of moveset

It depends on what level it starts at. For a hatched dratini, L20, 86+% to evolve and power up is about the lowest. If I was lucky enough to find a dratini at a higher level, I would accept a bit worse (maybe 66% @ L30).

82.2%. Got DB/HB. Pumped it around 2.4k CP. Got a new 95.6% Dratini now so I'll try my luck for a DT/O or DT/H.

I powered up a dragonite DT/O 64%iv as well as a Tyranitar B/SE 40%iv from L23 to L30. They are attackers for my immediate enjoyment.

I did an 84% recently, because it was level 29 and had 15 attack.

When it comes to Egg Hatches (20) I am more picky and wouldn't do anything under 89%

If I caught one wild, though I would power up on top movesets at much lower percentages. Especially if I was planning on only going to Level 30 for an attacker.

Even a Low IV, 31-32 = Level 30 with High IV

So for the right moves, 20ish candy and 20k dust is a LOT LOT cheaper than 125 candy for evolve for a chance for the moves

Any wonder Dratini should be worth evolving (and powering up if it gets a good moveset).

In my area, Dratini is easy to farm. I have three wonder Dragonites (SW/DP, SW/Hurr, SW/HB) and four wonder Dratinis, so I can afford to keep trying for a good moveset. Most players cannot afford to repeatedly spend 125 Dratini candies for a 1/3 chance and should thus power up whatever Dragonite they have.

Been lucky with mine. Caught Dragonair 100% and a Dratini 95% as well as hatched a 91% which are my only nites right now. Keeping with this trend I'll be very picky about Dratini IVs and wait for 88.9 min to invest into my 4th nite. Sitting around 180 candies now.

As far as a wild nite, never seen one. If I ever caught one with good moves I might power up if level was in 15-20 range or higher and IVs above 60

Completely depends on IV to level ratio. I would evolve a level 30 Dratini or Larvitar higher than 70% because I can get a usable mon immediately with minimal dust investment. This is especially if you’re going for an attacker. Attacking is a joke in this game and moveset completely trumps IV. If you need a defender, I would bump up my original IV statement to around 80% just so that I could get better gym placement. Hopefully this changes with the gym rework so people actually think about diversifying gyms and not just focus on CP regardless of how crappy it is (Gary).

My evolves are as follows...95, 95, 95, 91, 93, 95. With the time it takes to get Dratini candies they have to be over 90 for me.

That being said, all my 95s got sw/hb and my 91 got db/hb, so when I finally caught a 60% db/dc I took it to 3000 cp. Finally got some luck after that...

Dratini to evolve must be at least 91.1%.... Doesn't matter if caught or hatched. Not going to waste 125 candy on anything lower.

Dragonite to power up is slightly different. It depends on moveset and initial level. I recently caught a 27 level, 2489 CP, 20 IV (2,3,4), with DT/O moveset. Immediately powered up to level 30 so I can use it as an attacker.
But on the other side of that, a 17 level DB/DT moveset with 64.4 IV got sent to the professor.

87 but depends on D and S is 15, overall would be 91, I've dragonite catch at wild with 76 iv with db & dc at 3++ cp, gonna power him up since he have the best ms, but once I've the candy T-T

I have an 89 and 95 nite right now. Was lucky enough to roll DT/O. Probably won't power up the 89 anymore. He's already 2700+. I have an 84 IV Drateeny(XXS) that I am considering evolving however I'm sitting on 0 candies right now.
