In early levels, it is faster if you would find & attack Cybear with near-minimum spirit cost, so that less spirit is forcibly consumed. Then check the ATK Spirit you consumed to know how many minutes you have to wait before you find & confidently defeat the next-level Cybear.
On higher levels, or levels where you make use of all your spirits before you defeat Cybear, you'll most likely make use of the Cybear's "duration before it escapes" for natural spirit regeneration to be able to attack it again. Just don't forget to set an alarm or something so it does not escape. (preferably 8-15 minutes before it escapes)
Holly is obtainable at Lv70, which on previous Solo Conquests w/o LimitBreak the 3rd daemon was obtainable only at Lv80. 'Should be easier to obtain, methinks. They have increased the boss's overall HP for all levels though, so that might pose some difficulty for newcomers & veterans alike. Be mindful of the boss's HP spikes where the reward is the daemon him/herself.

Relatedly, is there any documentation on if transmigratable units keep their limit break during transmigration?
Oh gahd
Spring Breeze <3, I haet you now--! ;w;
She's a really great Phantom DEF team, since you don't worry about the offensive team having daemons of different colors/origins.
Coincidentally, I just run through
a wiki blog entry concerning limit-broken transmigrations.
Short answer:
Yes, they get to keep it. >w<
