Before I start binging YouTube videos on LOL guides, I figured I would get community advice first. 
Finally pulled Ægon and had a gem waiting for him. Have the resources to R5 him (just waiting on gold). What sig level does he need minimum? He’s currently 60sig or so which saves over 40%. 
Who else on my roster will make completion and exploration easier?
Anyone else to R5?
Specific counters for easy path?
I haven’t researched LOL at all up to this point so any advice is appreciated before I start watching YouTubes. 
Thanks my guys!
