League of Legends (LoL) Item: Muramana

Although it is able to solve the mana problem effectively for GP, the passive is not a favour for him since he only can proc the passive with his aa or q only. So if you build tear (muramana), you just sacrifice your early power spike (trinity force) but gain huge mana sustainability to farm into late game

Ryze's single target spells and autos both proc the Muramana damage, and he still gains AP from the mana. Seraph's embrace is the defensive option, and Muramana is the offensive option. Some people like to get both actually, and that still works. The Awe passives get a little wonky but it doesn't change the 2000 bonus mana getting converted into all that AP, the Shock Procs, and the Seraph's active. Also if you get Lichbane and Muramana on Ryze the burst becomes unreal as hell even without your spells.
Some Syndra builds involve getting Muramana as well because it lets her ult basically one shoc from the Shock procs. Also she can clean up a kill with her auto MUCH easier if the enemy manages to survive the burst with a little bit of health, and for many mages that's a sadly common occurrence where they just barely lack the dps on an auto to clean up the kill.
