_Zilean stores time as Experience at a rate of [2/3.5/5/6/12 at levels 1/6/11/16/18 based on level] per 5 seconds. _
**You start gaining experience 120 seconds into the game.
**
8-9 minutes is when Bot lane hit's lvl 6
You need, 2400 total to be lvl6
You get 6-7 minutes of passive exp before the enemy and you both reach lvl 6.
24 exp per minute
24 x 6-7 = 144 - 168 exp
Before we calculate how much sooner this get us lvl6
Two champions each gain 65.2% (one champions net's 100%) - I will discuss Mord below
One Wave Solo EXP Duo EXP
Melee Minion = 59 Exp x3 38 Exp
Caster Minion = 29 Exp x3 19 Exp
Siege Minion = 92 Exp x3 60 Exp
Total exp gained = 231
[You have roughly 90-98 exp to give to mord by the time you can use the Passive on him, this is equal to 1 siege minion/ 3 casters/ 1.8 melee. Still feel like a massive gain? ]
Siege spawns every 1:30minutes before 20minutes and starts it's first spawn at 3minutes
You get 4 canon minions by 9min
at 9:00 (which will be the 15th wave, with the 9:00 canon spawning at base)
You have a total of 2,061 Exp and 156 Zilean Passive Exp
So on the final Wave (When the 9:00 min wave reaches Lane) Zilean has to get the entire wave to have just enough to boots him and his adc into lvl6 So they get lvl6 1 wave early. The other Side hitting lvl 6 in 3 minion kills.
Now we factor laning lvl1-6 for Zilean and an ADC. To begin with, it's not in zilean's favor granted his high mana costs to spam bombs and his stun is near impossible to pull on on Gold+ players who are willing to trade a Flash to dodge the cc in exchange for a kill.
Against say a Leona or thresh, Zilean is massively outplayed in terms of his ability to support well during laning phase. So you are trading off % chance to win a lane in exchange to get lvl6 only 30 seconds faster than the enemy lamers. Which won't matter because they will lose maybe 2-7 cs at most during this time backing off, then they hit lvl 6. Suddenly they've got a more useful Support Ult.
Now considering how Zileans ult is most Powerful/successful in team fights and under towers. If your adc dies from a gank, they are not getting out because by the time the stasis ends and they revive with 600hp. It will just as quickly vanish.
The true strength of Zileans passive is in Midgame not Early, as the effects are literally a 3 minion advantage in lane before the enemy hit's lvl 6.
Oh and I thought I should mention, when a Zilean lane hit's lvl 6, he does not have the capability to suddenly turn on their enemies in comparison to other Supports who insta-cc lock you down. - Season 1-4 Zilean player
Zilean gave more Exp with his current 8% exp shared than this new one before you hit lvl6, so shut all this Bullshit "Their lvl 6 when we're lvl 4" crap.
New Zilean Passive 156 Exp (by lvl 6)
Old Zilean Passive 164 Exp (by lvl 6)
