Oberon is a kind of hybrid Warframe that relies on both offensive and supportive capabilities. Unlike Excalibur for example, Oberon has healing capabilities in trade of fight-flight abilities such as Slash Dash for Renewal, more so making Oberon an even more versatile frame.
Oberon has slightly more health than the average frame, which allows him to take more damage, and also allows him to cast Renewal on himself, allowing the extra health to give him time to cast the power.
Oberon can be played in unique ways, depending on the mods applied. Some users might want to try maxing out the health and using Oberon's healing abilities, or increasing the range and efficiency to make Reckoning more of a crowd-controlling ability.
