As a trinity player, I will say the perminant invulnerability is possible, but difficult to maintain until higher waves of defense (50+). This is because of exactly what was said. energy vamp is useless until the enemies can survive the hits. Best to just focus on snap heals and use link with an ogris or torid until then. I prefer torid. It's fun to attach some torid spores to my sentinal and run around like a toxic ancient with link up, melting everything.

Once you get to higher waves however, and energy vampire can do it's job effectively, it's not very difficult to maintain the energy pool to keep blessing up indefinately. Blessing being a 2 second cast time though...so you have 2 seconds without invuln. I have seen people drop during those 2 seconds, in waves above 60.
