I wouldn't worry about DPS. There's a lot of things you can do to extend the "enrage" for long enough to kill the boss even with DPS that you shouldn't have if you're up to Animus. If you are putting mini golems into the inactive larges at the start, after 4 siphons your massive will be at 32/36 and your large will be at 4/8, so pull the massive over and have your tank one shot the large to top the massive back off. This essentially means the boss will take an extra 2 siphons to hit 100. We only put golems into one inactive large at the start and the enrage felt reallllly long. If you put them into all 3 you'd have ages, probably longer than you will end up surviving.
