---------OUTSIDE ARENA------------
Not fixed yet,
At first five seconds out of arena, it gives 36% of mana

Then at 18 seconds you are full mana.
According to my calculations, following this logic you should be full mana in 13,8 seconds =~= 14 sec
Mana regeneration speed decreases after 5 seconds
Out of arena should regenerate the 300k mana in 20 seconds (atm: In first 5 seconds its normal, 10 seconds it goes slow, 15 seconds its really fast and ends on 18 seconds.)
Out of arena should be constant regeneration.

-------------INSIDE ARENAS------------
Mage food:
First 5 seconds goes slowly
After 5 seconds goes insane regeneration (fixed)
After 10 seconds goes insanely slow (not fixed)
Cobo cola:
First 5 seconds goes slow
AFter 5 seconds goes insane regeneration (fixed)
After 10 seconds goes insanely slow (not fixed)
After 13 seconds regenerates 1% mana per 2 sec (wrong)
