poseidon as an adc

Hi all! I am going to show you my build of poseidon as an adc. Normally poseidon is a mid player but he is also very usefull as an adc! feel I hope you enjoy it! Feel free to comment, postive or negative.

passive:

changing tides: poseidon's movement speed and power increases after succesfull basic attacks. at max tide he does up to 20% extra damage (only on abilities) and gains 10% movement speed. using an ability decreases the tide.

first ability:

Tidal surge: This does damage in a line. this ability goes quit slow and is hard to place. On the otherside it is a quit powerfull ability wich does 100/140/180/220/260 (+ 70% of your magical power).

Second ability:

Trident this ability is your most important ability next to your ult(if you go adc otherwise whirlpool) this becaus it makes your basic attacks stronger and this is what makes you an adc. it does 30/40/50/60/70 more damage per hit. It also is good for you passive. Every hit ads 20% to his tide.

third ability:

Whirlpool: This ability does damage at a certain point (radius 20) and does 15/25/35/45/55 (every 0.5 second for 3 seconds) and pulls enemies toward the center. this is a good ability for clearing lines but also as slow and you can use it before your ult so you can't escape from it.

fourth ability:

Release the Kraken!: this is your ult and so your most important ability. It is very helpfull in a teamfight and very strong! It does : 170/195/220/245/270 damage (+30% of your magical power) in the center it does : 180/220/260/300/340 (60% of your magical power) and also stuns the enemies. Enemies outside the center aren't stunned and does less damage.

well first of all you always need a starter item. I choose Vampiric Shroud it is very usefull. It has 20 damage, 5mp5 and gives you 100 health it also gives you per minion you kill 10 health and mana. After that you would like to buy ancient blade as it gives you already 10% attackspeed. Buy enough mana potions and health potions throughout the game. When you return to base buy shoes of the magi or shoes of focus. If you prefer the penetration above the cooldown choose shoes of the magi otherwise buy shoes of focus. after your shoes you upgrade your ancient blad to hastened fatalis, it gives you 30% attack speed and its passive removes your strafe penalty if you hit a basic attack succesfull. The next item you would want to buy is polynomicon this item gives you 75 magical power, 10% lifesteal and 300 mana, it's passive gives you after you used an ability 60% of your magical power as additional damage. The next item is demonic grip you buy this for its attackspeed, it gives you 25% attackspeed and 65 magical damage. It's passive is that if you have a succesfull basic attack it reduces the enemies defence by 7%. Then you buy chronos pendant pure for its cooldown, it gives you 75 magical damage, 5mp5 and 25 cooldown reduction. The last item you want to buy is rod of tahuti, this is the most powerfull item in the store. It gives you 125 magical damage and 5 mp5. Its passive contains that you gain 25% of your magical damage.
