1 AP Item I build on Urgot Just for the .8 AP ratio Is..

As Long as I have Damage increase based on Mana Soo I build times to times Mana/Health/AP for the shield? Sooo if I calculate the whole stat that this item give with Muramana. Max Stack Rod of Ages: 500Health 800Mana=16 Attack damage/64 Addtional Shield 120AP= 96 Additional Shield Its Actually good on Urgot Because of the Passive Sustain that it gives to him during laning Phase. No Stack Rod of Ages: 300Health 400Mana=8 Attack Damage/ 32 Additional Shield 80Ap=64 Addidtional Shield

Max Stack RoA= Rank 5 W= 220+64+96= A Shield Value of 380 No Stack RoA = Rank 5 W= 220+32+64= A Shield Value of 316

Now if you Take in consideration a Lv 18 Urgot with the following build:

A Urgot Shield: Urgot Mana: 1247+1000+800=3047 Mana Now Lets calculate his Shield: 8% of 3047= ~ 244 Shield Based on Mana 120AP= 96 Additional Mana Base Shield Value= 220 220+96+244= 560 Total Shield Value Now with The boots which give 10% CDR and Black Cleaver which gives 20% 30% CDR build Unless you get the additional 5% and go 9/21/0 in the masteries But we will take 30% since it is the standard build The shield is on a cooldown of 12 Sec.

8.4 Sec cooldown Shield of a Value of 560 in which is up for 7 SEC SOO URGOT HAS A 1.4 SEC cooldown on a Shield that Value of 560.

EDIT : You can change Duskblade for With an additional 250Mana. Shield Value Based on mana would be +20 10% too 580Shield on a 7sec duration and 1sec cooldown.

For Me This Soo called Urgot Buff hurts more Urgot than it actually help him. Passive Change is actually not that good. Unless Urgot hits his E soo the Damage reduction stack up faster. But against instant burst combo champion like Zed or Talon Hitting them with one auto attack is not enough. 5% damage reduction on 1 hit?
