some numbers on the new zilean passive

Zilean stores 2/3.5/5/6/12 (at 1/6/11/16/18) bonus XP every 5 seconds. If he stores enough to complete an allies level, he can do so, granting him the same amount of XP.

On summoners rift, leveling up requires the following amounts of XP (not cumulative)

1. 0
2. 280
3. 380
4. 480
5. 580
6. 680
7. 780
8. 880
9. 980
10. 1080
11. 1180
12. 1280
13. 1380
14. 1480
15. 1580
16. 1680
17. 1780
18. 1880

Zilean will store enough experience to fully level an ally of equal level (0 xp to levelup) after the following lengths of time: to level 2. 140 seconds to level 3. 190 seconds to level 4. 240 seconds to level 5. 290 seconds to level 6. 340 seconds

to level 7. 222.85 seconds to level 8. 251.42 seconds to level 9. 280 seconds to level 10. 308.57 seconds to level 11. 337.14 seconds

to level 12. 256 seconds to level 13. 276 seconds to level 14. 296 seconds to level 15. 316 seconds to level 16. 336 seconds

to level 17. 296.66 seconds to level 18. 313.33 seconds

Now, say that you have a teammate that is either REALLY behind in levels (or you are really ahead), or a guy just came back from AFKing (pizza op I guess)

A level 18 Zilean can store xp to fully level a teammate in the following time to level 2. 23.33 seconds to level 3. 31.66 seconds to level 4. 40 seconds to level 5. 48 seconds to level 6. 56.66 seconds to level 7. 65 seconds to level 8. 73.33 seconds to level 9. 81.66 seconds to level 10. 90 seconds to level 11. 98.33 seconds to level 12. 106.66 seconds to level 13. 115 seconds to level 14. 123.33 seconds to level 15. 131.66 seconds to level 16. 140 seconds to level 17. 148.33 seconds to level 18. 156.66 seconds

Should Zilean and an ally sit in base for the entire game, using only Zilean passive for levels, it would take 78.16 minutes to hit level 18.

Of course, you will almost never have an ally at 0 XP, as you spend most of it sitting in either a lane or the jungle. Expect these timers to be MUCH shorter in practice. Too lazy to calculate minion XP.

But hey, it seems like a pretty well balanced spell (you know, if you ban morde), nice job rito.
