It is easy to farm with him, I agree. I didn't mean to sound condescending; I like this build! :D

Ghost >>> Teleport. It might be confusing that I have teleport first, I'll fix that. I may also switch Teleport with Flash, since I agree a well-used Flash is awesome.

I'll switch level one ability to Fling. I haven't done this much myself, but I usually don't use a whole lot of poison anyway, mostly just when the minions are about to die to help farm a tad. From what I've seen, Fling is generally preferred by most Singed players anyway.

As for you needing a lot of farm for this build - It's not hard to farm as Singed!

I'll add the note for Tear of the Goddess.

As for Sunfire Cape vs Frozen Heart, I like Sunfire for its passive. The extra damage from Sunfire is actually very good and the mana from Frozen Heart only gives you just over 100 health. Frozen Heart can be good for more flings and some armor though... I guess either way works.

Hi! First of all, welldone and thank you for that guide.

However, I'm sorry but the second Rod of Age is:
1) optional. But of course, double Rod of Age is very viable with Singed (even 3! :D ).
2) WAY too late! (you won't have time to fully enjoy the passive)
Also, I'd add, as Rawrables said, that you should take Fling as the first skill because it prevents you to get in any trouble - you or your potential mate - and because you have no advantage to push very hard by poisoning the lane before having Fling!^^

By the way, I'm very glad you picked Flash as a summoner skill; it's really great when well used on Singed. But why do you prefer teleport more than ghost? You'll have farm anyway, wether you teleport to the lane or not, so isn't it better to have a skill that will be GREAT in teamfights, with your champion?

:D I dig; this build is quite nice but you really do need to farm a lot, but doesn't every good build? I give it a +1. Also, I like the layout, not to many pictures :D

You should make a note that the tear of the goddess should be your third purchase if someone is planning on making it at the end of the game. As for sunfire cape, it's just not as good as frozen heart because it gives you less armor and doesn't sync up with your passive. :3

+1 Just because of the bloodthirster comment. xD

I suggest picking fling at level 1 due to poison trail at level 1 being almost pointless and mana consuming. Also im a bit confused why you would take both teliport and ghost masteries. You can only use 1 at a time (in your main summoners on the build), so mention to change it per game. That 1 skill point can be put elsewhere Ex. 1 mana regen point or something.
if you were to use both, im not exactly sure if the teliport mastery is worth it anyway. Its your choice, but i would still only put 4 points in the mastery tier 1 tree. Ex. i would take one off preserverence if you think the teli mastery is worth it. Otherwise if you want, leave it. 1 mana regen isnt too important anyway

LOL i see what you did there :D
