Because it literally does everything in two ranks and it has two lv100 attributes for both Chortasmata and Carnivory.
100%(or close to) up time for the AOE heal as well as the double tick (Chortasmata+Carnivory) damage. AOE Invincibility with super short cooldown, the possibility to transform into something that gives you huge HP/SP boost if you bother to do that, or you could opt into Thorn which is another great DOT skill to add on the your kit.
For two ranks this is so strong it feels like a Rank 8/9 class.
Everyone’s end game is Velcoffer … And no there isn’t “straight up bertter classes than exo2” for these end game content. Velcoffer is a dark mob, no class in this game does holy property damage better than an Exo2.
In a Velcoffer team you typically have a linker 3 variant and spirit shock is gonna boost your damage by 25%, and Lethargy by 35%. I haven’t really looked into it yet but I am sure you can run 5 Exorcist or 4 Exorcist + 1 Linker to clear the dunegon faster than any other combos.
Btw, ALL worldboss are demons. Guess what Rubric does? It ticks TWICE, and guess what - most of them are ALSO DARK PROPERTY. In a recent patch worldboss all have different types of defense so Exorcist can’t fit into the one that can only be dealt with physical damage. But the one weak to magic defense such as Zaura/Marnox, Exorcist is definitely the top 3 class, if not the strongest class.
You essentially use 6 ranks to keep up Transmit Prana for some additional damage on your other non-Sadhu skills. I used to play a Sadhu3 PD, Sadhu needs more than 1 useful skill (possessing is ok but please don’t compare that with Druid’s Chortasmata + Carnivory, it’s laughable) for me to put 3 ranks in it.
With heals being so important now, I would not drop Cleric 2 as well. Fade is so handy in Velcoffer.
Bokor 3 gives you 2 skills in 3 ranks and your zombies get blown by Gregorate. Hexing is great really so this part is really up to personal preference, it fits perfectly with Druid anyway.
Sadhu 3 HAS to stick with Krivis 3 for it to work so you are actually comparing Sadhu 3 + Krivis 3 against Druid 2. Like I said, 6 ranks just to keep up a damage buff? I will gladly stick with my Chortasmata+Carnivory+Sterea Trofh.
