Ap udyr, so underrated and never played. Here is my build, enjoy
Please practice in normal games before getting him to rankeds. He is actually good for rankeds
I think AP udyr is way better than ad udyr... like for real.
Read chapter 3 to see why

PROS

- Awesome burst
- Better 1v1 than AD udyr (trick2g build)
- Natural tank
- Good CC for TF (and AOE damage)
- Fastest clearing time IN THE GAME
- Late Game GOD
- Rarely Played, people will never ban you.
- Never falls (early, mid, late)
- The splitpush potential is at yi/trynda level
- Godlike Split Pusher
- Best skin in the game

CONS

- Easily Kited
- Not as tanky as AD udyr (you still deal more damage)
- You will get insulted
- Tiger will only be useful after you buy nashor tooth
- Default skin is cancer

Why should you choose ap udyr over ad udyr?
Best way to Show you why is...

Q: Most noobish udyrs play tiger udyr, it falls way too much lategame but has a good early game. Phoenix is better on both versions. So... I will not analyse this
W: The lifesteal is much more useful with AD udyr, but the shield is Weaker since it scales with AP. 0.5 of your ap, it saves you a **** ton of times
E: its the same on both versions.
R: Udyr deals 200 damage every 3rd attack, and has a dot when activated surrounding udyr for 5 seconds. Experienced udyr players know that phoenix is way better than tiger, the damage is bigger, ad and ap versions. This is why AP udyr deals more damage than AD, Phoenix scales with AP, 1.25 baby. You will have 165 ap endgame

Full AP Phoenix Damage
165*1.25= 206 + Base damage from R = 481 every time you press R, almoust doble than AD. That is not so much... until you add the AS

Phoenix AP damage every 3rd Attack
165 45% = 74 + Nashoor Tooth = 100 (actually 99)
100+200=300 Every 3rd Attack; now, how much dmg can you deal in 5 seconds?

Phoenix AP Damage with AA included (at full build)
0.97 + 0.40 + 0.50 + 0.09 = 1,96 (lets count that as 2 for easier math)
1,96 + 4% * 8 = Max AS, 2.5
12 attacks every 5 seconds, 4 times phoenix proc.
4*300 = 1200 damage FROM BASIC ATTACKS EVERY 5 SECONDS.
But, We still forgot the AOE damage surrounding udyr for that 5 seconds
1924 Magical damage every 5 seconds, over 2000 if counting liandry.

2000 Magical Damage vs 825 with trinity and devorer (400 more damage when activating R)

AD udyr is slightly tankier tho, not by a ton of diference but he is still tankier (since you have better turtle stance)


Pick AD udyr if you need a tank, Pick AP udyr if you need... to win

If 1v1
R+4 AA+E+R+4 AA [repeat until you have slain an enemy sounds]

Split Pushing
For minion waves just R
When drinking towers just
Q+R+Q+R ( R helps you kill minions when so your own minions can help you, And Q is faster tower drinking)

Team Fights
E all people you can, then Just Burn APC/ADC with R and escape with W

You have a very good mid/late game, but a decent early so dont play like you are lee sin or xin zhao and tryhard.
Start in frog if in right side (smite), blue, red, Golems (smite if possible). Go back to base, after that focus on ganking and grabing some early kills. Dont waste time and farm a lot, having devorer will make you a demon in late game, so farm... a lot

Just Press R when split pushing and you will clear a whole minion wave in 3 seconds, you will drink towers in matter of seconds.
Remember to buy wards when split pushing, you will rekt all your oponents when 1v1 (exept jax, **** jax)

Another AP udyr strong point.
AP udyr deals a TON of damage in team fights, the trick is to stun the apc/adc before the team CCs you, one R and 3 AA and he will be dead by then. Your team needs to CC the support for you to secure the kill and not die by the time you stun the apc and adc.

As long as you have a hypercarry and a true tank support/top. Some CC for you to kill APC and ADC, you will be fine

My dream Composition would be:
Top: Nasus
Mid: Malzahar, Lissandra, Kennen, Katarina (only if having a leona)
JG: AP udyr (this is you)
Supp: Leona, braum, A good blitz
ADC: Vayne, Lucian, Draven or Tristana

Thanks a lot for reading to this point, it means a lot to me
Send me feedback, I have a lot of spelling mistakes (english is not my native lenguage) so please send me PM if you see them (you will see a lot)
I invented this build so I feel preety proud about my beloved AP udyr

With love,
Demnith
