General notes:
If you start a story arc, you cannot outlevel it; you're always
allowed to finish it. But beware; some contacts have more than
one story arc, even for bits of plot you might think of as a
single arc.

At levels divisible by 5, you may receive either of the two
appropriate Mayhem missions. These levels are not listed in the range
for these missions because you usually want to be sure which one you
are getting. Mayhems can't be done via Flashback, but if you have the
Hero Slayer badge you can use Lord Schweinzer to select which Mayhem
to run.

"pre-req" indicates a previous contact who you should do missions for
to unlock this contact. TFs and Trials generally only demand the team
leader has done the pre-requisites. I don't list Brokers because they
all work the same way.

In many cases, the available information on whether something finishes at 
levels 4/9/14/29... or 5/10/15/20... is outright contradictory. I'll try
and test these myself, but no promises. I have erred on the side of caution
in the mean time.

The order of things in this file is a bit arbitary. The idea is to
keep things you might be doing at the same time together - a strict
sort by either minimum or maximum level doesn't quite work. It's worth
peeking ahead into the next level tier to see what's coming up.

With changes to the game over the years, some "minimum" levels in this
list are more guidelines than rules. The maximum level for contacts is
usually when they stop talking to you; for other things, it's the
point where you can expect to be exemplared down.

Most Giant Monsters are their own category at the end because of the
way they really can be done any time and often have to wait
indefinitely for a badgehunting expedition. Complicated Accolades have one
entry in this list and many lines below.

The cape and aura missions and Mender Ramiel no longer unlock
anything, but you can still do them if you feel like it.

Essentially all incarnate content is co-op and is detailed in
