How to fight EA Abysia?

[Il Magno]

I try now to understand the various suggestions, here what I recognised:

comunions: quite clear; thx a lot for the renvigoration detail, it could be I was failing due to that detail missing. FYI I was very interested by your guide, but failed to feel confident when I tested it

bane lords thugs with eyes hields; ok clear; still I supposed to stay at the back firing everything (including WCs ) to the Abyssian guys, is it not more safe and effective? Than what does it mean "100 fr"?

I'll have swarm so do you u suggest to add it to the skelly spam tactic?

Leech: I have not that mastery level in blood, and honestly I don't know how the spell works: (as said before I consider my self a rookie )
