[Gameplay] Muramana Transform restores mana
When manamune transforms into muramana it restores at least 700 mana to your champion.
Reproduction 2/2 (that I have noticed)
Played urgot in bots, noticed I got about half of my mana bar suddenly when muramana transformed. (This would suggest it restores 1k)
Tested in a custom game with urgot and it restored a little over 700 mana (I was only missing about 700, and its highly likely it just restored me 1k with the 40 mana cost of my acid hunter taken out after).
Seems unlikely it is just a bug with urgot, but I'll leave that up to your team to ascertain!
If this is intended, then it would be nice to have it in the tool tip! 1000 mana is no joke!
