I've read people mainly suggesting Elemental Burn for Summoner, so I'm curious about how it compares to Ancient Library. I know summons only take into account your Intelligence (or other stats) at the time of summoning, and that Elemental Burn can give more Intelligence if you get all four elements up at once, but Ancient Library requires no added busywork beyond the initial cast and gives a big recovery to your mana, on top of lasting twice as long as Elemental Burn. Do any Summoners run Ancient Library, or is everyone all over Elemental Burn despite the tedium of getting the most bang for your buck that it presents? At the moment, I run Ancient Library since it's much easier to manage, and maintains its buff even for summons that I have to drop quickly. I've had no issues progressing up through Antwer Canyon so far, beyond occasionally getting gibbed by the hypermobile or mega-burst enemies (hi Outskirt's Arsonists and East's Shred, you're both butts and I want you to go away).
