I played him with bots after seeing this post and I honestly love him. His Q is on a rather long CD but with 40% CDR its a 7.2 CD. and it does nice dmg.
So, lets talk about his his Q. With about 668 AP it does 260(+482) Magic DMG, Rooting them in place for 2 Seconds (Max Rank) Thats pretty damn good already. Now, you can also have an ally click on the enemy you rooted and dash into them? OP OP OP. Ex. you're jungling and you go bot for a gank, your're ADC is farming minions and you run up behind him and Q em, you're carry sees this and as you are damaging them you're ADC dashes and helps you finishing them off. Or your'e support uses it and helps CC them even more. Its a beast spell.
Now, hes W instant bushes that turn you're melee magic DMG attacks into ranged? ( lasts a few seconds after leaving the bush and you can basically walk into a bush every few seconds to constantly stay with ranged) Oh and did I mention you get bonus Magic DMG? How much? with 688 AP thats 60(+206) thats still quite a bit. You can even build a nashers tooth do make it even more juicer? (Can someone help me on that one? How do you feel on that?) Oh and you can throw your bush into another bush if you wanna check it for 3 seconds. Oh and you can hold 3 bushes with a 13 second CD if I remember correctly.
Okay, his E is probs my favorite spell he has. Its a shield, it does DMG, and what?? it also slows the enemy it hits???? with 688 AP it shields you for 240(+551) DMG. Now like I said it also does Magic DMG 180(+482) and slowing them by 70% for 3 seconds with a 4.8 Sec. CD? Now remember the shield last 2 seconds so 2.8 seconds after it explodes you can use it again and slow them again? Can someone say OPOPOPOPOP?????
Now for his R I'm sorry I haven't paid attention to it much other than it being a Tibbers without the stun that I think deals more DMG or has more HP the more AP you have? If someone can explain his ult more I would appreciate that.
Now The items I build on him may not have been the ideal Items they did however did the job. The were in order of purchase Rylai's, Lonian booties ( You could try 6 Scaling CDR runes and grab the Sorc boots. next, I wanted some CDR so I got Morellonomiconm, Lichbane, finishing off with a Rabadons and Void staff. again, what would be your opinion on a Nashers Tooth on Invern? I would love to hear how others built him.
Now. This is probably the most I've wrote about any champion and some of my information or math could be wrong so If someone could correct me on it again, I would appreciate it. Thanks.
