Where are your boots? O_o

Instead of the Frozen Heart or the Locket, I'd get a Void Staff for added MagicPen; which will give your spells more boom.

Just know that unique passives dont stack so you wont have that much mana with 5 archangels, still the 400 mana bonus is good, but meh..

Also spell flux can hit someone 3 times, doing more than your AP in damage + 390 on level 5, and spell flux is especially good because you could hit someone with 40% of the other two bounces if you have your ulti activated, also Zhonyas ring makes the ulti even better

but nevertheless, Overload with a load of mana is also good, but picking innervating locket? meh
The cooldown on the passive is 4 seconds and as ryze youll be nuking, spamming your skills in less than two seconds, so its kindof useless
If you looked for a mana bonus thing you might aswel build another rod of ages or a banshees veil, wich have alot better passives

I can not agree more with Squall. You would be even better of if you would buy boot and five archangels staffs. Also I dont really get the attack speed rune.

uhh i forgot^^
Overload damages more with 700 Ap than with 4500 Mana :D

Spell Flux is still his best skill!
its deadly when you activate his ultimate.

4572 Mana => Overload deals 210 + 457,2 Damage + 45% of 185AP... 83,25 bonusdmg
=> 750,45 damage... hmm... not that much, cause Spell Flux and Rune Prison aren't very strong with 185 AP... Furthermore Overload is useless in Teamfights.

when having e.g. 700 AP after activating ulti ( yes, you can have more than 700... just an example )

Spell Flux deals 396 damage per "jump"
Teamfight, 5v5:
1 direct jump + 4 65%aoe-ulti-jumps => 1426 damage, to the whole team...


The only PRO is that you have 3000 hp...

anyways , -1 from me.
This Build is just not good

My only COmment Is your mastery Tree, Have you notice that its better to go a melle Dps built with a caster instead of the traditional CAster built of 9/0/21.

Just curious other than That seems PRetty good Using The fact the more mana he has the more powerful he can be. Very Interesting indeed plus 1 from me
