Just watch out for protect chains going on with hoffman and his guardian it is a mean combo. Your best bet to combat this is when you do damage to something in the protect chain you have to keep going so two swarms of spiders on something with abit of electrical fire or something like that could help. If you could get hold of a rusty alice she can be handy yes it cost 9 soulstones but she has a spell rust which ignors armour and causes slow with a dg flip of 3/4/5 so it is ok 12 inch range so not bad. She can also use ramos's ca which is better than hers so go for it plus if he has any abilities with it she can take them. You can not use any template things round hoffman within 3 inch of him as he negates it but best option is find the guardian/guardians and destroy the protect chains. Keep summoning either eletrical creation to destroy stuff or better summon spiders to swarm him once he starting to take damage keep going beware of the mobile toolkit hoffman can take it heals something it heals hoffman one wound so take this out priority.
Question.
