One thing not mentioned yet, is that once you defeat one of the Golems, the Anima that the Golem had, will transfer to the closest Golem that has "space" to support that amount of Anima. So if you have a Large Golem with full 8 Anima, and you kill it next to an inactive Large Golem that has 4 Anima on it, that 8 Anima will go to the closest Large Golem that has room to absorb all 8 of the Anima, or it will go to either the Massive Golem or Dark Animus.  Initially what you want to do, is take the active golems to any of the Large Golems that are "damaged", that way once they receive their max Anima of 8, they will just sit there and not engage in the fight because they are damaged, etc.  Then progressively move on to the Large Golems that CAN be activated. Then move onward to the Massive Golems and then the boss.  Reminder that you WILL want to have a few adds up while you are fighting/killing the boss himself.  Otherwise he will receive 100 Anima and wipe the raid.  **NOTE - even though his ability of "Siphon Anima" says it will not absorb the last 1 Anima of an active Golem, this does NOT apply to the ones that are damaged... he WILL siphon all Anima from those ones.  That part of the ability only applies to golems that are active in the fight.

1. The main disadvantage the 25-man has, is that ALL of the Golems are active, they dont have the luxury of having "damaged" adds.  The only thing I can suggest, is modified strats from strat 1 and 2 10-man.
   • Strat 1 - Similar to 10-man, but this would leave a large number of adds up at a time.  You could dump 2 small Golems immediately into a Large Golem, activating it.  Then kill the Large Golem next to another large Golem, which SHOULD cause it to dump all 8 of its Anima into it and activate.  And just go around the room like this, activating each Large Golem by killing one. (1 to 1 ratio essentially), then once you have the last Large Golem active, kill it and a bunch of little adds next to the Massive Golem and have it max its stacks out at 36, or at least close to 36.  Then kill that one next to the other Massive golem, so with luck, it will activate and have most, if not all, its stacks.  Then finish maxing its stacks and then activate the boss so it will hopefully start with 4 stacks.  This method will allow you to keep quite a few small adds up, 1 Massive Golem with a bunch of Anima, and also the boss with very minimal Anima so the # of abilities he can use at the start is minimal until the fight progresses.
   • It may take a bit of practice, but dump 1 small Golem into each of the 8 Large Golems.  This will bring your number of smaller adds from 25- down to 17.  At this point, you can dump 2 more small Golems into the Massive Golems and wipe them out.  Remember once you have the Massive golems up, and hopefully with only the initial 4 stacks of Anima from the transfer, you can kill them next to the Large Golems, causing a few of them to go from 4 stacks to 8 and becoming active.  Then you can work on eliminating the small Golems, causing the Large to go active, and then the Boss.  This way you also eliminate the Massive Golem threat, and should have the Boss up with a reasonable amount of Anima, but should only have to deal with red "Crimson Wake" clouds, similar to the 10-man.   But due to the amount of adds up total, this means that one tank will have the boss while the other tank could/should have anywhere from 2-5 Large Golems beating on him. And once the boss increases their damage by 100% each, could be wipe-tastic.

Again... overall goal is to try to figure out what combo of adds you leave up is best in order to defeat the encounter without wiping to increased Golem damage from "Empower Golem" or accidentally killing all the Golems and allowing the boss to get 100 Anima and wiping the raid.
