This makes sense to me. Thank you
Everything else mentioned makes sense too. Dmg aura triggering curse. But Conviction + cursed is a mix that doesn't help the lock builds.
Well you understood the combos on most build, but look at the last one here...
echo:
holy freeze + cursed
fire:
conv + whatever
abyss:
no bind demon, use 3x defiler, consume 1
echo for ubers / pure summoner:
fana + cursed
blood boil:
conv + cursed (you deal both fire and phys dmg)
you can eventually replace conv by infinity on merc, simply to have better amp propagation from holy freeze, but this is an expensive commitment for little upgrade while you could use insight on merc instead
